Pictographs record peyote use of earliest Texans

There is well-documented archaeological evidence indicating prehistoric peyote use, including pictographs and ancient peyote specimens found in caves and rock shelters in the lower Pecos River region of Texas. Anthropologist and archaeologist Dr. Carolyn E. Boyd has argued that the Lower Pecos pictographs provide the earliest record of peyotism.

Peyote pictograph at the White Shaman site

The above picture is Carolyn Boyd's rendering of the murals at the White Shaman site. The original rock art panel is high on a bluff overlooking the Pecos River. According to Boyd it depicts the hunt for sacred peyote, a powerful medicinal and sacramental plant. She also interprets it as a ritual re-enactment of the first pilgrimage that led to the birth of gods, the establishment of the seasons and the creation of the cosmos.

The following snippet of text is taken from a recent article on the pictographs at the Mystic Shelter site.


Boyd thinks these murals were inspired by visions the people experienced during trances brought on by the hallucinogen peyote. Some depict a warrior's journey to the "Otherworld." Some describe the hunt for the sacred peyote cactus and how the cosmos was put into place.

"The rock art panels are pictorial narratives of mytho-historical events - like putting the Old Testament creation story or Passover rituals into a visual format rather than textual," Boyd says.

The artists were hunter-gatherers, and lived in an extremely arid environment where deer were prized. Yet they used valuable fat from deer bones to make paint, illustrating the importance of the artwork in their culture, Boyd says. The murals - explosions of orange, red, yellow and black - would have jumped out from the daily landscape of brown, green and gray.

"It must have been spectacular," she says. "Can you imagine the impact that would have?

The record is still in the rock.

Surviving murals are found in rock shelters throughout the Lower Pecos region, where they were protected from rain, sun and wind. According to radiocarbon dating, most, including the ones at Mystic Shelter, were made 2,950 to 4,200 years ago. More sites are still being discovered.

If you (like me;-) dream of having a closer look at the pictographs the Shumla School arranges rock art field trips allowing you to examine the incredible imagery at first hand.

Back in August this year my grafted Lophophora diffusa var. koehresii (RS 1182; El Sabino, San Luis Potosí) flowered for the first time.

Despite the difference in size of the two Lophophora diffusa var. koehresii scions in the above photo they were both started as part of the same batch of seeds March 3, 2007. The largest of the scions was grafted June 7, 2007 and when the Trichocereus pachanoi stock grew an offset I grafted another seedling on it May 5, 2008.

Lophophora diffusa var. koehresii is described as being of smaller size than the other Lophophora species (possibly with the exception of the newly described Lophophora alberto-vojtechii), and having a dark green epidermis and pinkish-white flowers with a light brownish mid stripe. The flower and epidermis of my plant fit the description while it might be difficult to say anything useful about size as the plant is grafted. As mentioned above the plant is still very young but I'll watch it closely as it matures.

Flowering Gymnocalycium calochlorum

One more flowering cactus of the summer past. I don't have many Gymnocalycium plants in my collection but find the ones I have quite interesting – especially the large flowers and the naked calyx are fascinating (the genus name Gymnocalycium comes from the Greek for "naked calyx").

I bought this Gymnocalycium calochlorum (Mina Clavero, Córdoba, Argentina) a couple of years ago and it has been growing in my coldhouse since. It is coping well in this environment and is showing off a wealth of flowers each summer.

The pale pink flowers with the burgundy throat are quite beautiful and almost hide the plant.

Flowering Matucana madisoniorum

I was sorting out my photos and found a few pictures of plants that flowered this summer.

This Matucana madisoniorum plant was bought earlier in the summer from Kakteen-Haage to experiment with growing it in my coldhouse. The species is said to be pretty cold-tender so the chances for survival are probably not the best - it would be sad, though, not to see it display its beautiful orange-red flower again.

The species was originally described as Borzicactus madisoniorum by Hutchison in the journal of the Cactus and Succulent Society of America (vol 35 (6), pp. 167-172) and later transferred to the genus Matucana. The description was accompanied by the plate below.

Matucana madisoniorum has its natural habitat in Amazonas, Peru with a very limited distribution, it has been heavily collected and faces an unknown future in the wild.

Lophophora alberto-vojtechii at a glance

I recently received the 2008 (2) issue of the Cactus & Co journal describing a new Lophophora species, Lophophora alberto-vojtechii. The mature plants of the lilliputian species are less than 2 cm (0.8'') wide and the flowers are said often to be larger than the diameter of the plant.

Christmas cacti

The subject line is sordidly misleading as this post has nothing to do with Schlumbergera, Zygocactus or the likes ;-) On the contrary it describes a handful of extreme xerophytes that I treated myself to as an early yuletide present.

I'm just home from Charlotte, North Caroline where I had made a last minute arrangement with Mesa Garden to deliver some plants and seeds to the hotel I stayed at. As usual Steven's plants are hard grown and exquisite.

Ariocarpus fissuratus (SB 403; Crockett Co, Texas)

The A. fissuratus plants are nice and plump – the diameter at the root neck slightly exceeds 2.5 cm (1'').

I hope the A. retusus plants will survive in the coldhouse. As far as I can tell the plants from Cuesta la Muralla are some of the most cold tolerant of this species.

I only have a few Leuchtenbergia plants but I have grown increasingly fond of this interesting species. This particular variant is alleged to have a branching habit and grow to a height of 1 m.

There is always room for one more Epithelantha in your collection so I don't think the E. bokei plants need further explanation ;-)

The plants are now home with me and have been potted up. We are all eagerly awaiting the happy, sunny days of spring when the plants can be moved to the coldhouse.

Apart from the above mentioned plants I also bought a selection of seeds including Lophophora decipiens. I'm interested to see what the resulting plants look like – the description in the seed catalog is limited to an intriguing “powdery grey”.

Mumbai musings

I was supposed to have been in Mumbai this week. When visiting I stay, work, and spend my time off in the exact part of town where most of the terrorist attacks happened.

Fortunately my travel plans were changed but still I'm left with a bewildering array of feelings including sorrow, sadness, relief, anger, and fear – combined with a nagging disbelief of how scaringly few “ifs” it would have taken to place me at the scene.

I hope the city and people of Mumbai rise from this attack without giving in to the code of fear and violence imposed on them by the terrorists.

How soon after your Lophophora flowers can you expect a fruit?

I was asked this question in a comment a while ago. I could not give an answer that was more precise than flowers pollinated early in the growing season would set fruit later the same year so I decided to investigate the question further.

Friday July 18 I marked 5 freshly pollinated flowers on my grafted Lophophora williamsii (SB 854; Starr Co, Texas) with yellow pieces of cotton - the cotton was attached to the spent flowers using nail polish. The flowers were all pollinated 1 and 2 days prior to being marked.

All I had to do now was lean back, relax, and wait for the fruits to pop out.

*

Wednesday September 10 – less than 8 weeks after pollinating the flowers – all 5 fruits had appeared.

The first fruit (in the right hand side of the photo below) appeared more than a week earlier than the others and consequently looks a bit withered.

So a more precise answer to the question above is that you can expect your Lophophora williamsii plant to set fruits within 7-8 weeks after pollination. At least that is the case for a grafted plant in good growth.

Fruiting Epithelantha micromeris, take two

A few weeks ago I posted on my fruit bearing Epithelantha micromeris (SB1327; near Belen, New Mexico) plants. The color of the fresh fruit is a bright pinkish red that changes to a deep, warm, saturated blood red color as the fruit dries.

In close-up the Epithelantha micromeris fruits are strangely reminiscent of small (weirdly colored ;-) cacao pods.

When the last rays of the setting autumn sun shine on the fruits they assume an out of this world, glowing warm red color. I tried to capture it in the photo below but it doesn't quite do justice to the shimmering, radiant quality of the color (as should be evident by now I'm a sucker for the amazing palette of red nuances displayed by these little fruits ;-)

Copenhagen Botanical Garden revisited

The first weekend of September I visited Copenhagen Botanical Garden again. As described earlier the garden has a cactus house open to the general public as well as a propagation house that you can't enter. Flowering and otherwise interesting plants are put on display close to the entrance of the propagation house so even though you can't enter you still have a chance to enjoy some of the gems hidden away inside this house. An example is the beautiful flowering Ariocarpus fissuratus pictured below.

Lots of interesting plants are on display inside the publicly accessible cactus house. I especially fell for the lone Ariocarpus retusus tucked away among some larger plants.

Another beauty growing among much larger plants is a (slightly dehydrated) Astrophytum asterias.

The cactus house holds a large collection of Mammillaria as for example this Mammillaria prolifera var. texana that certainly lives up to its name.

Back in the propagation house a group of Strombocactus disciformis was also on display. The plants are growing in rocks mimicking their natural habitat.

My previous post on the Copenhagen Botanical Garden & Museum featured several pictures of the greenhouses so I won't bring any here except for a photo showing the top of the main greenhouse reflected in the water lilly pool in front of it.
