Our description is drawn largely from specimens which flowered in March 1908 and 
which were collected by Dr. Rose at Higuerillas, Querétaro, in 1905. Dr. Rose a hack 
this species very abundant in the deserts of Querétaro and living specimens brought vac 
by him have frequently flowered both in New York and Washington. These an el een 
with plants sent from Berlin, labeled ammillaria angularts longiseta. The Speries as he re 
treated is variable and more exhaustive field work might require some modifications in 
the description. ey, stoping (& ck 
The varieties Mammillaria cirrhifera major and M. cirrhifera fulvispina (Salm-Dyck, 
Cact. Hort. Dyck. 1844. 11. 1845) are without descriptions. The two varieties M. che 
fera albispina and M. centricirrha macrothele were listed as synonyms of M. subangularis 
| To M. subangularis is also referred M. sub-
