Ace, thanks for the info.

Kada, beautiful pictures, thanks! Amazing how similar they look even when they are that young:)

I found this study which contains some information regarding chemotypes of Lophophora Williamsi and Diffusa species. It's quite an interesting read, as it tries to link the morphological differences to chemical composition.

That's pretty interesting.
I have to wonder if those nonmescaline greyer Lophos were fricii rather than williamsii? It was not that long ago fricii was still getting lumped into williamsii.
It would be easy enough to figure out as fricii and williamsii have decent microsatellite differentiability established.

The molecular work on the recognized species and var. echinata will possibly be completed and published this year. Much of the raw data part is already done.
It will either appear on the CCI website or else a link to where it is available will appear there. I try to post a note here whenever I do any significant update there.

jourdaniana really should be referred to as cv. jourdaniana until someone can locate a wild population.
I like the proposed notion it might be a natural hybrid of williamsii and something else.
Kada's photo set is awesome.
There are some interesting images of Habermann's proposed holotype that are worth checking out at the CCI website along with some flower pictures he gave permission to include there.

What intrigues me most is that there appears to be *at least* a handful of distinct clone lineages present in Europe of jourdaniana. I'm looking forward to a day when someone stumbles on some someplace in Mexico. Its really sort of weird that no one has - considering how many populations Koehres and other serious cactus people are familiar with.
There are a number of things in horticulture that would be nice to sort out. Too bad the illegality of peyote can make it so tricky to deal with getting accurate information without risking safety for people and/or plants.

What are your thoughts on Lophophora alberto-vojtechii?

[trucha]

My very first thought was wondering what the nearest Turbinicarpus or other miniature population was.

That one either recently had or will soon have microsatellite work done so it can be compared to the other known populations. As soon as I hear something I'll post details or a link or someone else please do the same if its is before me.

Ya jourds are a very fun wrench int eh works. I love them. Are they also getting treated in the genetics work?

[analoge]

so beautiful

You can see how far behind I am in visiting this space or reading posts.
Yes, they are. There are several known distinct clone lines maintained in Europe and some of these provided samples. I'm not clear how many were run but four existed as options.
It seems probable all of that work will get published by next year?
