NEOMAMMILLARIA. 131 
Type locality: San José 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: pl. 24, as Mammillaria vetula.

Cespitose, the individual plant globose to short-cylindric, dark green; tubercles arranged in 8 
or 13 rows, a little woolly in their axils; radial spines 7 to 10, acicular, 6 mm. long; centra spines ror 
2, straight, stouter than the radials, 10 mm. long; flowers deep crimson, 2 cm. long; inner perianth-

Type locality: Mexico, but definite station not given. 
Distribution: Mexico, but range unknown. i a 
We have not seen living specimens of this plant but L. Quehl of Halle had it growing in 
1913 and sent us flowers which we have used in this description.
