with a brown-yellow cap.. I would have liked to put it with Cereus }, 

 This wem Id. have disturbed the transitiorr though which the hybrid s of 

 C. sneciosissimus with the Phyllocacti pernit quite beautif ullyi . 



In relation to the genus Cereus I would have beert very much in- 



clined to organize an E^hinocacti : Iwould o^ly like to know, how 



far this would lead ne ?" Bv whioh I nean, what species you put there?- 

 r ^ lne Pectlnati I know; it seeras however, that you. draw the kin of C. 

 cinaruscens Deppel the^e. in that you consider the C. Roener! as an 

 Echirocereus » This kin has becone quite nunerous with ne; even a por- 

 tion of the Nu 1 1 i c o s t a t i na v belong he^e, and these uncertainties 

 bother ne. The small kin of the Gennati (Forest p.397)# which uni - 

 formly is characterized by seeds prolif erating at the base and coh- 

 pressed spine-bundles, I would like also to put at the beginning of 

 the genus-, and the low and mostly prolif erating species close by.. 



Mr« Moriz sent a Cer . Carsten!! ; I don't know fron what area„ 

 to England, with 6 wing.-like, conrressed ridges^ covered with white 

 points or scales (ny Eo h » nyr i o s t i *rn a ) . It arrived dead, and I have 

 onlv its sceleton: It nust be a na^rnificert species thoun-h, which is 

 supposed to have well-scented flowers-, 2 - 3 on each pul vi 11 o t which 

 are only woolly without the least spine. 



¥öur 2üZ- Greg^II is also stränge; only, I cannot aeeept the 

 drawing of the berries as correct ! A fruit and flower on a stenr is 

 an offence a~ainst the symetry of the familyy at least against all 

 trlbus except the Peiresciae , which are here a^.d there short-steramed; 

 As I said also in the diagrosis of the ^enus, the Phylocacteae and 

 the Rhinsalideae seen to be foreign to the northern America, In Me- 

 xico they are rather common"; and where is their northern boundary ? 

 Tbl s is not known. - They are mostly plant s denarding warnth and 

 shade, , and grow like orchids? partly even E* piphytes. . The genus Phyllo-
