E. arantholdes looks to rae much like E* ¥i slizeni ; if , however, no st)e- 



cimen exists and no spine-bundles have been preserved, the name nust 



probably be elininated , as authority exists» Höh . Wi slizeri is also 



ba'll-shaned in early stages. I go through your letter in detail and. 



ans wer sequentially»- Ojd. cylindrica and vesti ta have the sane seed 



f ormation, and if the one has s^ort and the other long cylindrical sec- 



tions,can not be sep.^rated ary more than Bchinocereus tuberosus and 



phoe^io%3.s can be dlvided, but the name ovatus may be not fittlng, 



but I stuck to the old name. I do not know yet, if these Bolivian 



aoracanthae etc. etc. belong l^ere« I wo^ld be ve^y nuch obliged to you 



for flogen and fruit of Op. Clas/O f \ci d&$ « It was o^tainly a jrreat 



rai stake of S In to put C. Ilmer sls to Echinocereus « When flowers will 

 have to 



be known one will probably I put it to n ulyohniq/' ( = Cer ,lana tus Hunb) 

 I rayseif know few Cereus flowers (except Echinocereus ) ,an^ am 

 therefore not able to classify them; only, I must put Phyllocactus , 

 Echlropsls , Pf elf ferl with Gebens .1 did exanf^e Rhlpsalls carefully 

 and know the anatomical st^ucture, which is desoribed evervwhere wrong- 

 ly. The Paris speclmen of Op. nyriacantha and GallanafSjLa is mislea - 

 ding, It is a Plato^untia like the other, probably disf igured through 

 shrlnkage. 



Kam . Agassi zii is also unf o^turately re"oresented by a weak sne- 

 cinen, which ca^ be exnected to die too; thus I can not send it. The 

 new Echinocereus fron San Domingo has two fruit , which, however, a^e 

 not yet ripe» I do not send seed of Agave vlrrelrica to you (though 

 I may, I want to look if fresher ones are on hand) ,but a sraall plant, 

 w^ich' is really better. 



I send you seed of Cereus nhoe^iceus ( Sangre de Christo Gap) in 

 southern Colorado. I collected ralself seeds of Phoeniceus and gonaran - 

 thus in 187^ at the Upper Arkansas River in Colorado, but, unfortunate- 

 ly, can not find then just now. I enclose seeds of Cer . Eno^yi from
