from this species. Mammillaria crinita pauciseta De Candolle (Mem. Mus. Hist. Nat. 

 Paris 17: 112. 1828) may be of this relationship but we do not know it. 



Other varietal names have been given, such as M. glochidiata alba (Forster, Handb. 

 Cact. 188. 1846).

124. Neomammillaria trichacantha (Schumann). 



Maminillaria trichacantha Schumann, Gesamtb. Kakteen Nachtr. 133. 1903. 



Solitary, globose to short-cylindric, small; tubercles small, clavate, 4 to 5 cm. high, slightly 

 glaucous; radial spines 15 to 18, pubescent, acicular, white, 8 mm. long; central spines 2, brownish, 

 12 mm. long, one of them hooked; flowers red or yellow, 1.5 cm. long; inner perianth-segments 

 lanceolate, widely spreading, acuminate; style pale green; stigma-lobes white. 



Type locality: Not cited. 



Distribution: Undoubtedly Mexico, but known only from cultivated plants. 



The relationship of this species is somewhat uncertain. Schumann placed it next to 

 Mammillaria carretii and described the flowers as red, while Ouehl stated that the inner 

 perianth-segments are pale yellow, and this is clearly shown by an unpublished study of 

 Mrs. Giirke, made May 26, 1907, now in our possession. We have received such flowers 

 from Quehl. 



Quehl refers here Mammillaria hamuligera (sometimes written M. lamuligera) while 

 Bodeker would keep it distinct. We have received flowers from Quehl which correspond 

 with Mrs. Gurke's painting of M. trichacantha, but her plant may be different from Schu- 

 mann's type, which had red flowers.
