The herbarium sheets of this plant, sent us from the Missouri Botanical Garden, con-

The name Mammiillaria sulcata, first given by Engelmann, was changed by him to 
M. calcarata on account of M. sulcata Pfeiffer, but this was a later name and hence can

and range have been involved with other species. Miss Ellen D. Schulz sent us plants f rom

1922, which have enabled us to restudy the species in connection with its type now kept in 
the Engelmann Herbarium in the Missouri Botanical Garden. 
Mammillaria goerngii was given by Haage (Cact. Kultur ed. 2. 183. 1900) as a new 
name for M. calcarata. —
