Plant-body simple, cylindric, 3 dm. high, 12 to 15 cm. in diameter; axils of tubercles bearing 
white wool, the groove with r or 2 red glands; tubercles elongated, up to 25 mm. long, spreading, 
somewhat 4-angled but with broad bases; radial spines 8, spreading, rigid, horn-colored with black 
tips, 10 to 12 mm. long; central spines 1 or 2, stouter than the radials, brownish, 25 mm. long; flowers 
about 6 cm. broad, straw-colored; perianth-segments linear-oblong, obtuse; filaments reddish; style 
red; stigma-lobes yellow. 
Type locality: Mexico. 
Distribution: Central Mexico. 
Mammillaria polymorpha Scheer (Mihlenpfordt, Allg. Gartenz. 14: 373. 1846) is prob- 
ably only an abnormal greenhouse form of this species. 
Coryphantha aulacothele and C. lehmanni (Lemaire, Cactées 34. 1868) and M. macro- 
thele nigrispina (Schelle, Handb. Kakteenk, 243. 1907) are only names but are usually 
referred here. 
Mammillaria leucantha is credited to De Candolle by Steudel (Nom. ed. 2. 2: 97. 1841), 
but we have not seen such a name tsed by De Candolle. It may be a misspelling for M. 
leucacantha. Steudel refers the name to M. lehmannii, while the Index Kewensis states 
that it equals MV. recurva. 
Cereus lehmannii Hortus is cited by Forster (Handb- Cact. 245. 1846) as a synonym of 
M. lehmannii. -
