Hello The problem is that there are no data or photo of the suposed fossil. and if it exist, it will be the first discovery of a cacti fossilized. or they mean little pieces of a cactus? Anyway the tissue of peyote is very soft... I think that is impossible or very improbable that the tissue of that specie remains for so long. Here is a scanned part of a book of chilean cacti (but the author is from Australia). He works with cacti and made an interesting study with C14 cheers!!

very interesting but I dont have more information about it. Just this scanned page from New Cactus Lexicon (David Hunt, 2006) and here you can download the same image but bigger size: http://rapidshare.com/files/128158409/neoraimondia_NCL.rar good luck

hello MORG thanks for your comments! I love to see cacti in the wild... "sadly" chilean species aren't "medicinal" But anyway the make you feel so small and fragile that in some way, they change your mind... This is a list of some chilean species according to the last text of Backeberg Trichocereus chiloensis (Colla) Britton & Rose from San José de Maipo, Santiago. (near my house) Trichocereus coquimbanus (Molina) Britton & Rose, from Totoralillo, Coquimbo Trichocereus deserticolus (Werdermann) Looser, from coastal hills in Huasco Trichocereus litoralis (Johow) Looser, from Puerto Oscuro, Coquimbo Trichocereus skottsbergii Backeberg, from Fray Jorge, Coquimbo Helianthocereus atacamensis (Philippi) Backeberg, from Baños de Puritama, San Pedro de Atacama placed into Trichocereus atacamensis by Marshall & Bock Soehrensia uebelmanniana Backeberg (invalid), from Baños de Puritama, San Pedro de Atacama placed into Trichocereus uebelmannianus by Ritter (also invalid name). Now accepted as Echinopsis formosa (Pfeiffer) Jacobi (syn: Soehrensia formosa (Pfeiffer) Backeberg) Trichocereus glaucus var. pendens (Ritter) Backeberg, this year I hope to go to the extreme north of Arica (2.000 km far away from my house) and find them in Habitat... I hope to find one alive at last!! Trichocereus nigripilis (Philippi) Backeberg, mmmm... not clear description, it fix in eulychnia and trichocereus ( I dont use it, so I dont "look for" that plant) I hope that this help you to your study of this lovely plants best regards from Andes Mountains, Chile Juan "Spiniflores"

Hello I know that this is an old post, but I think that all of you will love to read the Kaktusy Special http://rapidshare.com/files/128012732/kaktusy_peyote.rar Copied from page 3: "The following arguments support the recognition of two sections: 1. The sections Lophophora and Diffusae differ chemically in the composition of their alkaloids. The Diffusae are a lot closer to each other in this respect and stand out clearly from sect. Lophophora. Sect. Lophophora contains the alkaloid mescaline. The mescaline content of the total alkaloids is 15-30% in sect. Lophophora, compared with a maximum of only 1.3% in the sect. Diffusae. Sect Lophophora contains 14-17% of the toxic alkaloid pellotine in its total alkaloid content, but is as high as 65-88% in the Diffusae! 2. Species of the Diffusae inhabit smaller, isolated habitats (ecological niches); L. williamsii, on the other hand, occurs over a vast geographical area 3. L. koehresii had been observed occuring together with L. williamsii. Equally, the habitat of L. fricci is enclosed within the habitat of L. williamsii. Despite of this, not a single instance of hybridisation or transitional forms has been observed wherever they are sympatric. This fact shows that they are incompatible and supports the present proposed classification. 4. L. williamsii retain the drier flower remains for much longer, while the perianth remnants are much more easily separated from the species of Diffusae. Diffusae plants shed their areolar wool more easily and earlier than in L. williamsii 5. Diffusae species have more numerous ribs (up to 21) of mostly undulating (sinusoidal) form. L. williamsii produces a maximum of 13 ribs, which are generally straight. 6. The soft tissues of the Diffusae plants with their delicate and thin epidermis in shades of green to yellow-green contrast visibly with the hard and tough, greyish green epidermis of L. williamsii. L. fricci mave a greyish green epidermis similar to that of L. williamsii. 7. The plans behave differently in cultivation. Most of the forms of L. williamsii are relatively resistant and will tolerate growers occasional cultivation errors. The Diffusae species, on the other hand, are much more sensitive to trauma. The above are some of the differences between the two groups. Further observations are still needed. We do, however, assert that the species L. diffusa, L. fricci and L. koehresii have features in common and, as a whole, are distinct from L. williamsii." ----------------------------- And actually, according to The New Cactus Lexicon (edited in 2006 by David Hunt) the genera Lophophora only have 3 species: L. diffusa (Croizat) Bravo 1967 L. fricci Habermann 1974 L. williamsii (Salm-Dyck) Coulter 1894 I hope that this data help to your study on this beautifull species cheers! from Chile, Spiniflores

Hello Here is THE CACTACEAE of Curt Backeberg http://rapidshare.com/files/100278445/Backeberg1.pdf http://rapidshare.com/files/100361685/Backeberg2.pdf http://rapidshare.com/files/100507754/Backeberg4.pdf http://rapidshare.com/files/100651677/Backeberg5.pdf If you have the complete file translated to english, please can you put a link for download it? sorry about my bad english, I'm from Chile, near Los Andes Mountains and near Trichocereus chiloensis saludos!
