THE CACTACEAE. 



Type locality: IMexico. 



Distrihution: Southern ^Mexico. 



ISIartius, who described this species, based it on a plant of Karwinsky, but did not cite 

 a definite locaUty; 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 Maimnillaria criniformis De Candolle (Mem. Cact. 8. pi. 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 Alammillaria decipiens, 



Mammillaria ancistrata Schelhase (Salm-Dyck, Cact. Hort. Dyck. 1844. 8. 1845). 

 given as a s3Tionym of ilf . ancistroides Lemaire, is referred here by Schumann, perhaps 

 wronglv.

JMammillaria ancistriua Hortus (Salm-Dyck, Cact. Hort. Dyck. 1849. 10. 1850) was 

 given as a sjnionym of M. ancistroides. 



To Ma)iimillaria ancistroides major (Salm-Dyck, Cact. Hort. Dyck. 1844. 8. 1845) was 

 referred ^1/. ancistrata as a synonym. Afterwards it was briefly described in Forster's 

 Handbuch. 



Alammillaria bergeana, a name from Hildmann's Catalogue, is referred as a synonym 

 of M. glochidiata (Schumann, Gesamtb. Kakteen 532. 1898), and so also is i\/. glochidiata 

 alba (Forster, Handb. Cact. 188. 1846). 



Mammillaria ancistroides Lehmann (Delect. Sem. Hort. Hamb. 1 832) 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 prolijera. 

 The former is based on Mammillaria crinita De Candolle (Mem. Mus. Hist. Nat. Paris 17: 

 112. 1828; Cactus crinitus Kuntze, Rev. Gen. PI. i : 260. 1891), and has the central spines 

 straight (at least so shown in the illustration, but described as hooked), and must be excluded
