NEOMAMMILLARIA. I07 



Schumann refers here Manimillaria longispina Reichenbach (Suppl. Terscheck Cact. 

 Verz.; see also Walpers, Repert. Bot. 2: 301. 1843) and M. obconella Scheidweiler (Hort. 

 Beige 4 : 93. f. 6. 1837), but we are uncertain as to their relationship. To the former Walpers 

 refers as a sjoionym M. galeoUii Otto. 



Mammillaria dolichacantha Lemaire (Forster, 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, somewhat umbilicate at apex; tubercles ovate, 

 naked in their axils, not lactiferous; spine-areoles tomentose when young; radial spines stiff, bristle- 

 like, 25 to 30, white, spreading; central spines i (sometimes 2 or 3), rigid. 



Type locality: Mexico. 



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 when he drew up 

 his description, for he described two varieties, one of which has bristles in the axils of the 

 tubercles, which are never found in Neomammillaria elegans as we have treated it here. 



Plants named Mammillaria elegans are to be found in most collections of cacti, but the 

 name is often applied to several closely allied species. A plant from northern Mexico, 

 Mammillaria chinocephala, resembles it very much but has milky tubercles. Other species 



* Here De Candolle referred Cactus columnaris Mocifio and Sesse (De Candolle, Prodr. 3: 459. 1828), which 

 Schumann has inadvertently taken up as Mammillaria columnaris Mocifio and Sesse (Gesamtb. Kakteen 565. 1898).
