Anhaloniucr To this stränge tribe belongs probe bly £. turbinlf orrai s t , 

 now extremely rare in Europe» »which I did not find in Mexico.. The flo- 

 wer is small, nannilaria-like, the fruit smooth, ^reen; the seed ex- 

 tremely fine, dust-like,llght brown,shiny und er the raagnifying glass,, 

 losins* its ability to geminate very fast,but preminates very easily 

 if so^ f resh. This Ech. is supposed to grow near San Pedrito. - 

 May-be E. Asterias belon.p-s also here, of which one knows even less. I 

 did not find it rayseif, but received a specinen sent fron LaRinconada. 

 Unf ortunately, it dl ed very soon. 



E. horripilus I have not found in Mexico. Though I never saw it in 

 flower, I always considered it a true Echinocactus . Many Echinocacti " 

 have a naked or nearly naked ovary, e.g. those, which Pfeiffer combined 

 under the division Gymnocalffciura ; f urther « even with Ech . setispinus 

 the berry is provided with very few sraall soales. 



£> f etisrdnusj has the pecullarity most rare with cactl, that it blooms 

 constantly through the e^tire Sunner. . 



E. Scheeril is the only Echinocactus known to me, which produces sto- 

 lons. It grows in the Sandy plains near Rio Grande del Norte; if one 

 lifts a larger plant fron the ground,one finds, that 3 to 4 horizontal,, 

 pencil-thick stolons to 1 foot eraerge, which at thelr ends have not in- 

 frequently started little plants, very similar as custoraary with the 

 Agavae. - Have you not observed this ? This beautiful Echinocactus is 

 now also extremely rare in Europe. • 



Pil . senilis I found near Hacienda d e Guadelupe between Zacualti - 

 pan and Ptotonitco el grande in very large quanti ties.The older plants 

 carry a long, thlck, , velvety tuf t f pointing to^d Söuth-east, f rora which 

 the flowers develop. Though I cut down several plants with nuch ef f ort,, 

 I could find only dried flowers and no fruit nor seed s. Even nor^stri- 

 king was for me, tkat to find almost only f ull4.gr own', large plants in 

 thousands of specimens, while I had to search a long tlme.to find about
