Mammillaria viridiflora

127. Neomammillaria viridiflora sp. nov.
Globular to short-oblong, 5 to 10 cm. long, the plant-body well hidden under the closely appressed radial spines; tubercles terete, small, naked in their axils; radial spines 20 to 30, widely spreading, white with brown tip, bristle-like, 10 to 12 mm. long; central spines much stouter than the radials, 1.5 to 2 cm. long, brown, one or more of them hooked; flowers greenish, narrowly campanulate, 1.5 cm. long; fruit globose to ovoid, 10 to 15 mm. long, purplish, very juicy; seeds minute, 1 mm. long.
Collected by C. R. Orcutt on Superior-Miami Highway, near Boundary Monument, between Pinal and Gila counties, Arizona, 4,700 feet elevation, July, 1922 (No. 608, type), and by Mrs. Ruth C. Ross near Tula Spring, south of Aravaipa, Arizona, June 1922 (No. 14).
Here perhaps are to be referred plants collected in New Mexico by 0. B. Metcalfe (Nos. 797, 803, and 820) and probably that part of Mammillaria wrightii which came from Santa Rita. Mr. Orcutt has repeatedly written to us about this green-flowered species, which we are now able to separate very distinctly from both M. wrightii and M. wilcoxii.
Dr. Forrest Shreve has also reported a green-flowered species from Arizona which he states is common in oak-woods.
