New to me

Post by fanaticactus »

We had a miserable Winter in Vermont. No, it wasn't too cold...it was actually too mild. Most of my cacti in the greenhouse never went dormant. And I didn't want to water them because that would just encourage them to continue to grow, I thought. I lost over two dozen cacti. I won't try to replace them all, but I'm building back with a few interesting ones I've found locally. I can make semi-educated guesses on what these are, but not all. I've looked in all my usual sources for ID's but can't find anything close enough to make a determination. The numbers on the closeups are for easy reference. #1 I think is a Rebutia; #2 I thought might be a Mammillaria but there's no typical fuzz where it should be. #3, a Lobivia/Echinopsis of some kind? #4, definitely a Mamm, but which species? I believe I found #5 in Cacti, The Illustrated Dictionary and seems to be Lobivia maximiliana v caespitosa. Could that be right? #6 is not dried up and dead; it is solid, but wrinkled, and a brownish color, and looks to me like a Gymnocalycium. Any help would be much appreciated.

#2 doesn't look like a Mammillaria - maybe Thelocactus hexaedrophorus?

Yes, I think so. I had one several years ago but it was bigger and because of that looked different. But now that I think back, I can see the resemblance. I hardly expected to find a Thelocactus at my local nursery. Thanks, greenknight!

#2 looks like Thelocactus rinconensis based on tubercle shape. T. hexaedropborus has simpler tubercles.

Agree with TimN - #2 Thelocacactus rinconensis. #1 Rebutia sp., #3 Matucana polzii, #4 Mammillaria (hahniana)?, #6 Gymnocalycium schickendantzii (?), #5 Lobivia maximiliana caespitosa seems correct.
