NEOMAMMILLARIA. 107 
Schumann refers here Mammillaria longispina Reichenbach (Suppl. Terscheck Cact. 
Verz.; see also Walpers, Repert. Bot. 2: 301. 1843) and M. obconella Scheidweiler (Hort. 
Belge 4:93.f.6. 1837), but we are uncertain as to their relationship. To the former Walpers 
refers as a synonym WM. galeottii Otto. 
Mammillaria dolichacantha Lemaire (Férster, Handb. Cact. 213. 1846) and M. dolicho- 
centra picta (Salm-Dyck, Cact. Hort. Dyck. 1844. 9. 1845) were never described.

Simple, obovate to globose, 5 cm. in diameter, radial spines stiff, bristle- 
naked in their axils, not lactiferous; spine-areoles tomentose when young:

Distribution: Central Mexico. . . 
This species was based on Thomas Coulter’s No. 48 from Mexico but no definite 
locality was cited. The type was not preserved nor is there any illustration extant of the 
Original. De Candolle may have had more than one species before him w on e en ae 
his description, for he described two varieties, one of which has bristles in the it he a 
tubercles, which are never found in Neomammillaria elegans as we have treated it here. h 
Plants named Mammiilaria elegans are to be found in most collections of cacth, bat t e 
hame is often applied to several closely allied species. A plant vom aoe other soevion
