Well, in fact my planst on the pictures are AG11, my SB 236 were all orange and at the time being I keep only two. Amog AG11 2 seedlings flowered yellow with perfect=hermaphrodite flowers which is unusual for E. coccineus and I suspect that the Ecer. dasyacanthus genes manifest this way.

Glad to meet you again, Brian. The Northern Area Weekend 2009 was absolutely marvelous. Superb place, superb organization and really nice people. Give my thanks to all with whom you are in touch.

SB 236 is E. coccineus ssp. rosei and originates from Jarilla Mts. in New Mexico. This place is famous for the Echinocereus hybrids of E. dasyacanthus and E. coccineus ssp. rosei. The intermediates are known as E. roetterii. All three, roetterii, dasyacanthus and coccineus ssp. rosei are quite frost...

I suggest to keep the whole crew together. Other Copiapoas seem not to synchronize their flowering, C. solaris might behave the same. I am amazaed how fast are your plants growing, mine is more than 10 years old and 4 cm diameter only. I hope that within several decades your seedlings shall become a...

'lizard skin' forms of hypogaea can be found in habitat, I've seen them approximately 10km North of Chanaral.

Certainly you are right, they are in habitat but they are the type variety Cop. hypogaea var hypogaea found and described by Ritter.

Yes, it is our KK Plzen show. Usually about 30 members show their plants and sell spare seedlings. The show is held in mid June, this year from 14. till 18. I think the poly tunnel was the esential think for the show because it provides the exposed plants with enough light and thus the members are n...

Well the pests in collections we can manage but more serious are pests in wild. The picture was taken above Amaicha del Valle in Tucuman, where the rural donkeys recently invented that their hoofs are harder than the strongest spines of Leucostelle (Tr. pasacana). They learned how to kick off the sp...

TJ 84 is clearly C. hypogaea, the ecotype with smooth epidermis often called C. hypogaea var. barquitensis. If the place of collection and plant shape corresponds with the description, identification is much more easy rather than if place or plant shape or either do no correspond. :smile: I still wo...

Anyway, thanks for reassuring me that leaving them until the end of March will be fine, and for pointing out that they are tough! The majority of Pteros that I have are still fairly small. I take it that your advice to remove the top growth refers only to Pt. tuberosus, valentinii and megliolii. Wo...
