NEOM AMMILLARIA . 



131 



Type locality: San Jose del Oro, Hidalgo, Mexico. 



Distribution: Hidalgo, Mexico. 



The above description was drawn in part from a plant which flowered in Washington 

 on November 8, 1912, and which had been sent to us by L- Buscationi from Catania, Italy. 

 This plant gave off numerous young ones from the axils of the tubercles, but it has died. 



Mammillaria vetula major Salm-Dyck (Walpers, Repert. Bot. 2: 270. 1843) is said to 

 be the same as M. grandiflora Hortus. If so, this must be different from M. grandiflora 

 Otto, which we have referred to Neolloydia conoidea. 



Illustration: Nov. Act. Nat. Cur. 16: pi. 24, as Mammillaria vetula.

Type locality: Mexico, but definite station not given. 

 Distribution: Mexico, but range unknown. 



We have not seen living specimens of this plant but L. Quehl of Halle had it growing in 

 19 13 and sent us flowers which we have used in this description.
