NEOMAMMILLARIA . 



109 



Our description is drawn from the original, supplemented by specimens in the Engel- 

 mann Herbarium obtained from Salm-Dyck's garden in January 1857, which consist cf 

 two packets, one containing a few spine-clusters and the other several withered flowers 

 and nearly ripe fruits; these latter are labeled "Baumann 857." Engelmann and Coulter 

 compare this species with Mammillaria micromeris but we believe that it is related to M. 

 elegans and its allies. 



It seems to have been described from specimens of Haage of unknown origin but 

 supposed to be from Mexico; Coulter's reference, on the statement of Budd, that it occurs 

 within the southern border of Pecos County, Texas, is to be doubted. 



Coulter renamed Mammillaria microthele because of an older Cactus microthele. 

 Martins used the name M. microthele in 1829 (Hort. Reg. Monac. 127) but without descrip- 

 tion. The names M. brongniartii Hortus, M. microthele brongniartii, and M. compacta 

 Hortus (not Engelmann, 1848) have been used (Salm-Dyck, Cact. Hort. Dyck. 1849. 9. 

 1850) but without descriptions.

 Mammillaria pseudoperbella rtifispina Quehl, Monatsschr. Kakteenk. 26: 94. 1916. 



Solitary, or few together, globose to short-cylindric, very spiny, depressed at apex; tubercles 

 short-cylindric ; radial spines 20 to 30, setaceous, white, short; central spines 2, one erect, the other 

 turned backwards ; flowers small, purple ; perianth-segments narrow-oblong, with an ovate acute 

 tip; style longer than the filaments, pinkish; stigma- lobes 3, obtuse. 



Type locality: Mexico. 



Distribution: Central Mexico. 



The flowers of this plant were not known when first described nor was its exact origin 

 known. An illustration of it was given. We have also received a dead plant from Bodeker. 

 This illustration and specimen seem to point to a species which has been frequently sent to 

 us from Oaxaca by Conzatti, Reko, and Solis. These plants from Oaxaca normally have 2 

 short, stout, divergent, central spines. In one specimen sent by Professor Conzatti in 1922 

 the central spines are often 2 and 4, with one of the centrals more elongated and those 

 near the top of the plant connivent.
