Lophophora williamsii v. caespitosa graft

I’ve been pretty busy lately and completely forgot to post on the 3rd anniversary (June 7) of my Lophophora williamsii v. caespitosa graft. The main head is 5.5 cm (~2.2'') wide and the total width of the scion has increased to approximately 13 cm (~5.1'').

The Lophophora williamsii v. caespitosa scion is grafted on a Trichocereus bridgesii stock and was repotted early this spring (hence the supporting props).

I’m fascinated by the explosive growth induced by the Trichocereus stock (for comparison you can check the posts on the same plant one and two years ago) but the appearance of the plant tends to become increasingly freakish.

The plant doesn’t bloom with the same vigor as it grows – until now it’s only flowered once.

Flowering Lophophora jourdaniana, take two.

One of my Lophophora williamsii v. jourdaniana plants is flowering again – this time with the full cooperation of the sun, resulting in a much more well-developed flower compared to the previous one.

My two Lophophora williamsii v. jourdaniana plants are almost in full compliance with Habermann’s description (rose-violet perianth, pistil, and filaments; persistent spines on young areoles) but the open flower clearly contradicts Habermann’s claim of cleistogamic flowers (i.e. flowers that do not open and are self pollinated). Apparently Habermann misunderstood or used this term incorrectly as the photo accompanying the type description also shows a plant with an open flower ;-)

Like many other species of cacti (including the other Lophophora species/varieties) L. jourdaniana has thigmotropic stamens, i.e. stamens that when touched fold in around the style (as is evident for the front stamens in the rightmost picture).

The following stop motion video provides a better illustration of the thigmotropic mechanism - I'll try to make a higher quality movie the next time the plant flowers.

It seems like the movie couldn't be embedded - you can watch it at http://youtube.com/watch?v=NcID667nZX8

Flowering Lophophora jourdaniana

One of my Lophophora williamsii v. jourdaniana plants flowered last week. I’m hoping the early flower can be seen as a promise for more flowers this season – last year and the year before last the plant only displayed one flower.

The sun was obscured by clouds most of last week and consequently the flower never unfolded completely before it withered. The picture above shows the flower at its peak – it’s still beautiful in all its rose-violet charm, but for comparison you can check the fully unfolded flower from last year in all its splendor.

The power of grafting – 3rd anniversary

Today one of my Lophophora williamsii (SB 854; Starr Co, Tx) plants is celebrating its 3rd anniversary as a scion grafted onto a Trichocereus pachanoi stock. The plant has set 4 offshoots and grown to a width of 7.3 cm (~2.9''), 3 of the offshoots are wider than 4 cm (~1.6'') while the smallest just exceeds 2.5 cm (~1'').

The plant set 9 flowers last year and has already displayed two flowers this year. The dried fruits resulting from last season’s flowers are clearly visible in the above photo along with the withered remains of the two “fresh” flowers from this week. The photo below was taken a couple of days ago while the flowers were still at their peak.

Usually I assist the plant with its self-pollination but this season I will not interfere. I’m doing this to test to which degree the plant will be able to set seed without any help – of course I can’t do anything about the thigmotropic reactions of the stamens or insects taking liberties with the flowers ;-)

A couple of days ago a flower bud also appeared on the largest of the offshoots and it will probably bloom within a week; unfortunately I will not be home to witness it. If all the offshoots begin to flower and the main shoot continues to flower in its usual pace, I’ll soon grow more seeds than I’ll ever need.

Since last summer the Trichocereus pachanoi stock has also been allowed to grow an offshoot. Usually I remove these from stock plants in order not to starve the scion, but this one appeared almost at soil level and I decided to let it grow and later graft one of last years Lophophora williamsii (SB 854; Starr Co, Tx) seedlings onto it (these seedlings are the result of self-pollinating the above plant, i.e. technically they are clones of the mother plant). I had planned to do the graft today, but I’ll leave for the Netherlands tomorrow and decided to postpone doing the graft till I’m back.

I was in doubt whether or not to include the last photo but decided to do it anyway. I’m fascinated by the dreamy image of the flowers backlit by the soft light of the setting sun, filtered through the foliage of a sprawling Bowiea volubilis. My girlfriend finds the picture boring and “too green” – but who is she to trust, she’s not into cacti ;-)

Update - April 28, 2007
Fortunately I made it home from the Netherlands in time to experience the pup unfold its first flower. The flower is not as sturdy as those of the main shoot, but what’s to expect from a novice ;-)

Today I also removed the dried fruits of last season’s flowers and freed the seeds.

A day at the New York Botanical Garden

During a recent vacation in New York City my girlfriend and I decided to leave the turmoil of the city behind for a day and head for the more tranquil environment of the New York Botanical Garden. I had great expectations for the visit, partly because the garden was established by Nathaniel Lord Britton (of Britton and Rose fame) and partly because of the NYBG Virtual Herbarium, a great information source on the Cactaceae family. As it turned out, the garden’s collection of live cacti is rather sparse; fortunately a handful of flowering Mammillarias saved the day ;-)

Even though the number of cacti plants is limited, the Enid A. Haupt Conservatory is a spectacular place and we spent hours exploring it – also, the orchid show was on during our visit, making it a lot easier to convince “She Who Must Be Obeyed” that we should examine the different plants in detail ;-)

Lophophora and Epithelantha - experiments in cold hardiness II

Since 2004 I’ve experimented with growing Lophophora, Epithelantha, and Acharagma in an unheated greenhouse in Denmark. The winter this year has been damp but not very cold - the coldest temperature registered in the coldhouse was -5C (23F) – so even the L. diffusa plants are doing great.

Lophophora williamsii (SB 854; Starr Co, Texas)
Lophophora williamsii (SB 854; Starr Co, Texas)

The L. williamsii plants (sown May 2004) are thriving in the coldhouse. The epidermis is glaucous bluish-green, much truer to the type than plants grown in my windowsill. All my cold grown Lophs are wrapped in horticultural fleece during winter – not so much because of the temperature, but to avoid attacks from various critters. This kind of damage is not a problem with the spine covered species.

In 2005 I sowed L. diffusa and L. decipiens to grow in the coldhouse. Especially the L. diffusa plants had a hard time last winter and only 2 survived. Both are now doing fine and are developing the typical yellowish-green epidermis.

Lophophora decipiens

L. decipiens is not a “good” species; it’s probably just a cultivar form of Lophophora fricii (I couldn’t obtain any collection data for these seeds either when I bought them). Anyway, the plants are doing well and are getting ready to go 8-ribbed at an age of two.

I’m growing both “regular” Epithelantha micromeres and Epithelantha micromeris v. gregii. The gregii variety seems to be a faster grower than the regular micromeres; it also has a very beautiful coverage of spines, as illustrated below.

Seed starting Lophophora, Ariocarpus, and Epithelantha

The last couple of days I’ve been busy starting the next generation of plants from seed. One of the more interesting lophs this year is a variety of Lophophora williamsii originating from El Oso, Coahuila, Mexico. According to The genus Lophophora – Kaktusy Special 2, 2005 this variety forms massive clusters with individual heads measuring up to 15 cm (5.9'') in diameter! Unfortunately it seems the El Oso site is severely threatened by agricultural activities.

I’ve sown the following Lophophora seeds this year:

  • Lophophora diffusa v. koehresii (RS 1182; El Sabino, San Luis Potosí)
  • Lophophora diffusa ssp. kubesai (JJH 0010892; Puente Mezquitio, Querétaro)
  • Lophophora fricii (RS 404B; Viesca, Coahuila)
  • Lophophora williamsii (MMR 89; El Oso, Coahuila)
  • Lophophora williamsii (RS 428A; Cuatro Ciénegas, Coahuila)
I have great expectations for the Lophophora diffusa ssp. kubesai. According to the retailer’s seed catalog this variety is prone to offsetting (in contrast to the typical single stemmed L. diffusa specimens), eventually forming multi-headed clumps as pictured below. Lophophora diffusa ssp. kubesai Lophophora diffusa ssp. kubesai In addition to the Lophophora seeds I also started a handful of Ariocarpus from seed:
  • Ariocarpus fissuratus (JDL 26; Hot Springs, Big Bend, Texas)
  • Ariocarpus fissuratus (VVZ 204; Terlingua, Texas)
  • Ariocarpus fissuratus (VVZ 205; North of Alpine Texas)
  • Ariocarpus kotschoubeyanus v. macdowellii (RS 134; Hipolito, Coahuila)
I’ve specifically selected extreme northerly types of A. fissuratus as most of the Ariocarpus seedlings will be moved to a coldhouse later in spring (along with half of the L. williamsii and L. fricii seedlings) to experiment with the cold hardiness of these species. The move is also a necessity because my windowsills are getting crammed ;-) Finally, the following Epithelantha seeds (also for the coldhouse) were sown:
  • Epithelantha micromeris (JM 101; Sitting Bull Canyon, New Mexico)
  • Epithelantha micromeris v. gregii (MMR 179; El Oso, Coahuila)
The seeds were bought from Jan Martin Jecminek and Jaromír Dohnalík – details for both are listed in the seed and plant retailers section. All seeds are sown in a mix of limestone gravel, regular soil, and loamy sand (mixed in a 2:2:1 ratio). The pots are placed in closed bags where they will stay until the seedlings are well established - check out the post on growing cactus from seeds for more information on seed starting.

Curtis’s Botanical Magazine – plate 4296 (vol. 73, 1847), Lophophora williamsii

Curtis’s Botanical Magazine – plate 4296, Lophophora williamsiiSince my early days as a “Lophophora aficionado” I’ve heard and read that the first illustration of Lophophora williamsii appeared in Curtis’s Botanical Magazine in 1847 (plate 4296). This fact seems to be very well known – probably because of Anderson’s book Peyote, The Divine Cactus – nevertheless it’s been next to impossible to find a good reproduction of the illustration.

These days are over. The Botanicus Digital Library has scanned the material and made it available online. Below you’ll find copies of the scanned illustration as well as the accompanying description; the description is also reproduced in textual form.

_____________________________

A neatly-formed species, which has a very pretty appearance when its starry blossoms are expanded. We received several plants of it at the Royal Gardens of Kew, through the favour of the Real del Monte Company, from the rocky hills of their district of mines in Mexico, with many other treasures. It flowers in the summer months.

DESCR. Our largest plants do not much exceed the size represented. They grow in a tufted manner and are often proliferous, as in the instance here shown: the parent plant being, as it were, stifled or subdued by its offspring. Each individual is turbinate: from the base to the crown, or summit, terete, of an ashy brown colour, and scarred with close transverse lines, occasioned, it would appear, by the progressive withering and contraction of the tubercles: the summit is broadly convex, but with a deep depression in the centre, glaucous, traversed from the centre outwards by 6-8 furrows, and thus divided into as many convex ridges, and these again, transversely, but more or less deeply, into rather large, rounded, more or less confluent unarmed tubercles, each of which has a dense tuft or short pencil of compact erect hairs:--no aculei. Flowers proceed from a young tubercle, near the centre of the crown. The base of the calyx is downy. The petals lanceolate, rather numerous, white, externally tipped with pale green, and having a rose-coloured line down the centre. Stamens yellow. Stigma of four spreading rays.

In Deep South Texas, peyote harvest dwindling

I’m aware that this Seattle Times article has been available on the net for some time; but I think it fits well with the theme intoned by the posts on proper peyote harvesting techniques and the Huichol peyote pilgrimage, so here goes...




In Deep South Texas, peyote harvest dwindling

By Sylvia Moreno (2005)

Salvador Johnson, licensed peyote distributor
Salvador Johnson is one of four licensed peyote distributors left in the United States. He has harvested the plant for 47 years.

MIRANDO CITY, Texas — In the heart of Rio Grande brush country, Salvador Johnson works a patch of land just east of the Mexican border that is sacred to Native Americans.

Spade in hand, eyes scanning the earth as he pushes through the spiny brush, Johnson searches the ground carefully. “This is good terrain for peyote,” he says. “There’s a low hill — the rain starts on top and goes down to water this — and there’s a lot of brown ground.”

He stops, points the tip of his shovel at a 3-inch spot of green that barely crests the soil under a clump of blackbrush and announces: “This is what you look for. You look for something that is not ordinary on the terrain. I saw that green.”

One of the last remaining “peyoteros,” Johnson, 58, has been harvesting the small round plant in and around this tiny community for 47 years — long before the hallucinogenic Lophophora williamsii cactus was classified as a narcotic and outlawed by federal and state governments. Then as now, it is for use by Native Americans as the main sacrament in their religious ceremonies.

Johnson is part of a nearly extinct trade of licensed peyote harvesters and distributors, at a time when the supply of the cactus and access to it is dwindling. The plant grows wild only in portions of four southern Texas counties and in the northern Mexico desert just across the Rio Grande.

But some Texas ranch owners have stopped leasing land to peyoteros and now offer their property to deer hunters or oil and gas companies for considerably higher profits. Others have plowed under peyote, and still others have never opened their land.

On the ranchland that is worked by peyoteros, conservationists are concerned about the overharvesting of immature plants as the Native American population and demand for the cactus grows.

“Will there be peyote for my children and my children’s children?” asked Adam Nez, 35, a Navajo who had driven 26 hours with his father-in-law from their reservation in Page, Ariz., to stock up on peyote at Johnson’s home.

That question and possible solutions to the problem — such as trying to legalize the importation of peyote from Mexico, and creating legal cultivation centers in the United States — are being studied by members of the Native American Church, Indian rights advocates and conservationists.

There are an estimated 200,000 to 500,000 members of the church in the United States. Although 90 percent of the peyote in North America grows in Mexico, the number of ceremonial users there — mostly Huichol Indians — is a small fraction of the number in the United States and Canada.

“In effect, you have a whole continent grazing on little pieces of south Texas,” said Martin Terry, a botany professor at Sul Ross State University in Alpine, Texas, who specializes in the study of peyote.

The church was incorporated in 1918 in Oklahoma to protect the religious use of peyote by indigenous Americans. Its charter was eventually expanded to other states, and in 1965, a federal regulation was approved to protect the ceremonial use of peyote by Indians. In 1978, Congress passed the American Indian Religious Freedom Act.

But subsequent conflicts between federal policy and state drug laws precipitated the passage of a federal law in 1994 to guarantee the legal use, possession and transportation of peyote “by an Indian for bona fide traditional ceremonial purposes in connection with the practice of a traditional Indian religion.”

The law extends protection against prosecution for the possession and use of peyote only to members of federally recognized tribes.

“Over the last 40 years, there have been lots of equal-protection defenses to criminal prosecution thrown up, with people saying ‘my use of this controlled substance is religiously derived,’ ” said Steve Moore, a senior staff attorney with the Native American Rights Fund.

Though not considered addictive, peyote is included in the Drug Enforcement Agency’s list of Schedule I controlled substances along with heroin, lysergic acid diethylamide (LSD), marijuana and methaqualone.

Although the DEA acknowledges the importance of the hallucinogenic cactus to the religious rites of Native American peyote users, the agency says the drug has a high potential for abuse and has no accepted medicinal purpose in the United States.

The Texas Department of Public Safety has licensed peyote distributors since the mid-1970s, when the number in the state peaked at 27. It dwindled to four last year. State records show that only three distributors have harvested and sold peyote so far this year.

For the past five years, an average of almost 1.9 million peyote buttons have been sold annually, according to state records.

Huichol peyote pilgrimage

Once a year groups of Huichols (an indigenous people with a population of about 20,000) embark on a pilgrimage to collect peyote, a trip taking them approximately 300 miles (~480 km) from their home in the Sierra Madre Occidental in western Mexico to the peyote fields in San Luis Potosí (a sacred area known as Wirikuta). The rituals surrounding the pilgrimage have been described in detail by e.g. Carl Lumholtz and Ted Anderson, but Nicola Frioli’s photos are the best pictorial documentation of the journey I’ve seen yet.

It’s interesting to compare the above plants with the peyote harvesting technique recommended by modern research.
