Type locality: Mexico. 



Distribution: Central Mexico. 



A plant, collected by McDowell, was seen in the collection of the Instituto Medico 

 Nacional in the City of Mexico, but no specimen was obtained. 



Mamniillaria columbiana vSalm-Dyck (Cact. Hort. Dyck. 1849. 99. 1850) is probably 

 to be referred here. It is doubtless of Mexican rather than of Colombian origin. 



Mammillaria eriantha (Pfeiffer, Enum. Cact. 32. 1837), referred here by Pfeiffer, was 

 never described. 



Mammillaria cylindracea De CandoUe (Mem. Mus. Hist. Nat. Paris 17: iii. 1828) 

 is referred here by Schumann and also by Pfeiffer and Otto, but the description of it would 

 suggest a different species. Kuntze changes the name to Cactus cylindraceus (Rev. Gen. 

 PI. i: 260. 1891). Here is also referred Mammillaria cylindrica flavispina (lyabouret, 

 Monogr. Cact. 88. 1853).
