Specimens referred here that are prevailingly narrower-leaved than 
usual though otherwise not closely alike,—f. stenophylla, occur from Ari- 
zona (Pajarito Mts., Trelease, 362; Chiricahua Mts., Pilsbry, 1906; Blu- 
mer, 1531), and New Mexico (Silver City, Greene, 1880). To this per- 
haps, is referable a specimen from the Sierra de la Laguna, Lower Cali- 
fornia (Brandegee, Mar. 24, 1892), not readily placeable elsewhere.

very obtuse, small, scarcely 1x1.5-2 em., rather abruptly subpetioled for 
about 2 mm. Spikes solitary, short (scarcely 10 mm.), puberulous, with 
2 or 3 joints about 20-flowered when staminate: peduncle 2 mm. long: 
seales puberulous. Fruit white, subglobose, glabrous, 3 mm. in diameter: 
sepals pubescent at least at base, suberect.—Plate 45.
