Plant-body simple, cylindric, 3 dm. high, 12 to 15 cm. in diameter; axils of tubercles bearing 

 white wool, the groove with i 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, ID to 12 mm. long; central spines i 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 (Miihlenpfordt, Allg. Gartenz. 14: 373. 1846) is prob- 

 ably only an abnormal greenhouse form of this species. 



Coryphantha aulacoihele and C. lehmanni (Lemaire, Cactees 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 used 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 M. reciirva. 



Cereus lehmannii Hortus is cited by Forster (Handb. Cact. 245. 1846) as a synonym of 

 M. lehmannii.

All the synonyms cited above may or may not belong here. Our description is com- 

 piled mostly from Pfeiffer's. 



Mammillaria curvata (Pfeiffer, Enum. Cact. 15. 1837) was given as a synonym of 

 Mammillaria exsudans.

 f. 8, No. 30, as Mammillaria glanduligera. 



* This binomial is credited to Lemaire by Riimpler (Forster, Handb. Cact. ed. 2. 395. 1885), but as a synonym 

 of Mammillaria brevimamma exsudans.
