Cactus densispinus Coulter, Contr. U. S. Nat. Herb. 5: 96. 1894.
Mammillaria pseudofuscata Quehl, Monatsschr. Kakteenk. 24: 114. 1914.
Globose, 6 to 10 cm. in diameter, entirely hidden by the dense covering of spines; tubercles short and thick, green, not milky; radial spines 25 or more, slightly spreading, about 1 cm. long, whitish or pale yellow; central spines 5 or 6, longer than the radials, 10 to 12 mm. long, the upper half or third dark brown ; flowers purple without, yellowish within, 1.5 cm. long; seeds obovate, reddish brown, 1 mm. in diameter.
Type locality: San Luis Potosí, Mexico.
Distribution: San Luis Potosí, Mexico.
We have had this plant in cultivation since 1912, specimens having been sent to Washington by Mrs. Irene Vera from San Luis Potosí. Our plant is probably a part of the type collection of Quehl's Mammillana pseudofuscata, as Mrs. Vera wrote us that she had sent speciments to Germany which had been identified as M. fuscata. Our plant has been compared with Eschanzier's specimen from the same locality which is the type of Coulter's Cactus desispinus and we are convinced that they are the same; Coulter's type is now in the Field Museum of Natural History.

Étymologie
Neomammillaria: du grec neos, nouveau, car le nom de genre Mammillaria créé par Haworth en 1812 avait été employé par Stackhouse en 1809 pour un genre d'algues, et Britton & Rose étaient opposés à la conservation du nom d'Haworth opérée au congrès international de botanique de Vienne en 1905 en contradiction avec la règle stricte de l'antériorité.densispina: du latin densus, dense, et spina, épine: à dense spination.
