One of the best things about late winter/early spring are Echinomastus blooms. Submitted for your approval:

Nice! Don't usually think about the flowers on these.

Ditto to the previous comments... The flowers seem to overwhelm what appears to be a small cactus. True?

Echinomastus johnsonii and erectocentrus are pretty heavy on spination. E. intertextus, at least those in cultivation, seem to have much less pronunced spines. The habitat shots from the search by genera section of the cactiguide homepage show much shaggier spines.

I don't think so. Here-check out another perspective.

My cactus is one of three pictured from Andy Cook's collection on the E intertextus page. I bought these from Ondy when he was going out of business. The one pictured above is the only one I've managed to keep alive.

Interesting, I don't think I knew that. I kept in touch with him for some time after. He moved to Montana and was managing a storage place and writing poetry. I'll have to see if his e-mail is still the same.

Beautiful! Love the color of the stigma lobes on intertextus. Well grown!

Really really nice!




At first blush the flowers rather resemble Notocactus roseoluteus (except petal color of course).

I see what you mean.

I'm really looking forward to vars. erectocentrus and acunensis blooming in tandem later this week. Hopefully I can get some hybrid seeds. I'm still not sure what the differences are between the two :-k.

The differences between erectocentrus and acunensis are dramatically visible in older plants, after adult characters have developed. They are also adapted to completely different microhabitats. acunensis will only grow in finely decomposed granite, on gentle slopes with an angle of about 15 degrees or so. erectocentrus grows mostly in limestone and is more widely adapted to different soil and orientations, and grows in less xeric habitat. They are also florally different in some respects.

Yes, the differences between older plants of the two varieties (species?) is readily apparent. I'm still learning.
