NEOMAMMIIvLARIA. 1 49 



Cespitose, globose to cylindric, light green; tubercles setose in their axils, in 8 and 13 spirals, 

 cylindric; spines all puberulent; radial spines 9 to 11, setaceous, white, i cm. long; central spine, 

 I to 4, brown, i or 2 hooked; flowers rose-colored, 12 to 13 mm. long. 



Type locality: Mexico. 



Distribution: Mexico, but range unknown. 



The plant is known to us from description only. 



121. Neomammillaria saffordii sp. nov. 



Plants small, globose to short-cylindric, 3 to 4 cm. high, dull green, nearly hidden under the 

 dense covering of spines; axils naked; spine-areoles when quite young slightly woolly, but early 

 glabrate, circular; spines all puberulent under a lens when young; radial spines 12 to 14, somewhat 

 ascending, but in age more or less curved outward, when just developing with bright red tips and 

 white bases, later the lower part becoming yellowish; central spines single, stout, reddish, 1.5 cm. 

 long, hooked at apex; flowers 2.5 cm. long, rose-colored; outer perianth-segments tipped by long 

 bristles, the inner obtuse; stigma-lobes green. 



This beautiful little species was collected by W. E- Safford, February 3, 1907, near 

 Icamole, Nuevo Leon (No. 1250). Two plants, which were sent to Washington, flowered 

 June 21, 1912; but they have not done well in cultivation. The plants sprout freely in 

 cultivation and in this way we hope to distribute material to other collections. It is near 

 Mammillaria carretii and was so figured by Dr. Safford, but it differs in several important 

 respects from that species. It is named for Dr. Safford, the author of a very interesting 

 paper, entitled Cactaceae of Northeastern and Central Mexico (Ann. Rep. Smiths. Inst. 

 1908), frequently referred to in these volumes.

Cespitose, forming a large hemispheric mound; individual plants globose to short-cylindric, 

 olive-green; tubercles cylindric, their axils a little woolly, but not setose; radial spines 14 to 16, 

 setaceous, white; central spines 3, brown, one hooked at apex; flowers large, 2.2 to 2.5 cm. long, 

 salmon or rose-colored (Nicholson says white with line of rose down each petal) ; fruit 5 mm. long. 



Type locality: Mineral del Monte, Mexico. 



Distribution: Hidalgo, Mexico. 



Salm-Dyck (Cact. Hort. Dyck. 1849. 7, 81. 1850) describes the three following varie- 

 ties: sericata, rosea, and triuncinata, some of which may belong elsewhere. Of these 

 Schumann recognizes only the last. The first Lemaire has referred to a different species, 

 Mammillaria glochidiata sericata Lemaire (Cact. Gen. Nov. Sp. 40. 1839).

Densely cespitose, forming clusters sometimes 15 cm. high; tubercles cylindric, green, shining, 

 8 to 1 5 mm. long, well separated from one another towards the tip, obtuse, terete ; radial spines 1 2

 one of them hooked; flowers white; inner perianth-segments lanceolate, acuminate; style longer
