150 THE CACTACEAE. 
Type locality: Mexico. 
Distribution: Southern Mexico. 
Martius, who described this species, based it on a plant of Karwinsky, but did not cite 
a definite locality; Hemsley, however, records Karwinsky’s plant as from near San Pedro 
Nolasco, Hidalgo, at 7,000 to 8,000 feet altitude. 
As it is a high mountain species it would doubtless not remain long in cultivation. 
Pfeiffer refers here Mammillaria criniformis De Candolle (Mém. Cact. 8. pl. 4. 1834) and 
transfers his two varieties rosea and albida to M. glochidiata as variety rosea and albida 
(Enum. Cact. 37. 1837). Mammillaria criniformis must be very different, for it has only 
8 to 10 radial spines and one central spine, and this yellow. The two varieties also may 
belong elsewhere; in fact, the variety rosea has been referred to Mammillaria decipiens, 
Mammiilaria ancistrata Schelhase (Salm-Dyck, Cact. Hort. Dyck. 1844. 8. 1845). 
given as a synonym of M. ancistroides Lemaire, is referred here by Schumann, perhaps 
wrongly. 
Fic. 165.—Neomammnillaria longicoma. 
Fic. 166.—Neomammillaria glochidiata. 
Mammillaria ancistrina Hortus (Salm-Dyck, Cact. Hort. Dyck. 1849. 10. 1850) was 
given as a synonym of WM. anctstroides. 
To Mammillaria ancistroides major (Salm-Dyck, Cact. Hort. Dyck. 1844. 8. 1845) was 
referred M. ancistrata as a synonym. Afterwards it was briefly described in Forster’s 
Handbuch. 
Mammiullaria bergeana, a name from Hildmann’s Catalogue, is referred as a synonym 
of M. glochidiata (Schumann, Gesamtb. Kakteen 532. 1898), and so also is M. glochidiata 
alba (Forster, Handb. Cact. 188. 1846). 
M ammiullaria ancistroides Lehmann (Delect. Sem. Hort. Hamb. 1832) is usually referred 
to this species but it must go elsewhere; it has setae in the axils of the tubercles, the radial 
spines are 6 to 8, and the hooked spine is brown at tip. 
Schumann (Gesamtb. Kakteen 532. 1898) describes two varieties, crinita and prolifera. 
The former is based on Mammillaria crinita De Candolle (Mém. Mus. Hist. Nat. Paris 17: 
112. 1828; Cactus crinitus Kuntze, Rev. Gen. Pl. 1: 260. 1891), and has the central spines 
straight (at least so shown in the illustration, but described as hooked), and must be excluded
