Fürthen you ar.r 5 many of ny correspondents err in believing ne 

 to be a cactus fancier. I am this neither nore nor less than that I 

 am a friend of all plant f amilies and or kinds, which in one way or 

 another attracted my attention, as e*g« the Isoetes; the Isoetes, the 

 Juncus species, etc. etc. Also, I have no oportunity to cultivate 

 them and the poor tMngs nust stand much nistreatment» I cultivate 

 thera only to the point where they can serve ne for Observation and 

 study. But I have various friend s here, who much want the plant s to 

 be removed , and who do take care of them ( without understanding any- 

 thing ahout them otherwise). I received a f ine collection of Qpuntias 

 from prince Solen, which was taken in for care by a garden enthusiast. 

 They na de narveleous progress (planted outside during Summer) , and many, 

 which never set fruit in Europe, do so excellently (thus the three spe- 

 cies of Nopalea) • 0. g ran dl s flowers profusely but did not set fruit; 

 it is probably identical to my 0p . stenopetaia ; my new nexican 0«ar bo- 

 re scens etc. etc. - the most of the Boundary etc. Cactus I have never 

 had in culture, or, they have died long ago; to the first belong 

 A^halonium f i ssu ra tum, Ce^, Oer. cteyo \ d<L5 etc.; to the latter M» mlcro- 

 meri sl •>> las! acantha , e t c . Lasiacantha I saw once in f lo^er, micromeri s 

 never. By the way, you may believe ne, that I exanine a live and bloo- 

 ming cactus today much nn^e exactly than 20 years back, because one 

 does progress, going deeper and deeper. Much of wha.t I published. 2o or 

 15 years ago, would be much improved today; that is the reason that I 

 am sad, that much or scii almost all of the living material is lost and 

 may not be obtained again so soon. though, once in a while something 

 comes again into my ha^ds, thus, during these days, a Sedum from 

 Arizona ( Sonoran) , however in. bad shape; Some things, specially seeds 

 you shall gladly have.
