A^halonium .I consider as a definitive progress. Host likely, the 

 Lenchtenbergia will belong the^e too # - Did you find the Felec yphora 

 in Mexico ? And in what area does it exist ? Your Observation^ about 

 M.micromeris are most interesting. As Pfersdorff does not mention it 

 in his catalogue, I must^fear, that you did not send any seeds.- 

 Your Man, chlorosti^ a is most probably M. Pottsii f Siheer ( in Caeta- 

 ceae by Salm) | the latter I found near Rio Graves del Norte near the 

 little city of Guerero.it 1s the only one known to me with a greerr 

 sti graa«- 



Damort ieri I did not find at Rio Grande del Norte, but on 

 a little river.which is also called Rio Grande near Ocuilcalco; it 

 forms large trees with a stem of 6 - 8 1 1 and a mighty crown.with bran- 

 ches directed straight up. Your Cer. Chiotilla does not seem to be 

 that, if I may permitted to say so, judßring ^ron my §" bi*?h seedling t! 

 which Pfersdorff has sent me. 



I would like to doubt that ny Ech, saltillensis could be identi- 

 cal with H.robustispina Engelnr. ,though both must be closely related. 

 But the former grows only in the vicinity of Saltillo and has flesh- 

 colo-ed flowers, the latter comes from Sonora and has yellow blooms.- 

 Mixed with E, saltillensis I found still another unquestionable Echl - 

 nocactus with alraost the sarae spine formation as saltillensis g in - 

 stead of nipples it has large, broad, 5-6 ed*ed (at the base) hunps, 

 with a strongly wo ol y -f ur r o w, ad pre s s ed very flat on the plant, Body 

 of plant is ball-shaped and very vi vi dl y shiny green. Did von not 

 find thls Plant near Saltillo T I had then collected many speciners, 

 but most of then have already spoiled before I could even pack them, 

 because each had a large, thick, white worm (sie. E.D. ), which had 

 eaten the plant from the inside.. The few speclmens, which got to Berlin 

 were baptized Ech.inocactus Poselgerianus . but soon died off., Unfortu- 

 nately I have neither flower nor fruit s o^ this beautiful plant. I 

 possess only one dried specinen.
