or acutish, attenuate or abruptly contracted at base, sparingly toothed, 
mostly rather long petiolulate, glabrous, or, with the petioles, pubescent 
when young; fruit 1’ long, terete at base, widening into an oblong, obtuse 
wing, calyx. persistent—Ash Meadows, Nevada, and also collected by Dr. 
Bigelow on the Mexican Boundary Survey, at Devil’s Run Cajion, but not 
mentioned in the report. A stem of twelve years’ growth, 1$ inches in 
diameter, has a smooth grayish brown bark.”—Not having access to speci- 
men, I have taken the above from Mr. Watson in Cat. Pl. Wheeler, p. 15. 
Species reduced by Dr. Gray in Syn. Fl. N. Am. p. 74, to a variety of the 
following—Puate XXII. 
FRAXINUS PISTACLEFOLIA, Torr., forma tomentosa—Tomentose, Teaitete 
5, almost sessile, lanceolate, Sei RTs serrate, tomentose, especially be- 
neath; samara 1’ long, seminiferous portion terete, 1’ in diameter, 6” long, 
equalling the narrow, lanceolate wing. Very variable in shape and haitri- 
ness of the leaves, so, much so that, in describing it a second time in the 
Botany of Whipple’s Expedition, Dr. Torrey changed the name from F. 
velutina, as it appeared in Emory’s report, to the present name.—Ash Creek, 
Arizona, at 5,000 feet altitude (302). Grows to be 20 feet — with a 
diameter of 18 inches.
