elongated pubescent panicles, covered in the bud by broad-ovate tomentose scales rounded 

 at apex; calyx cup-shaped, densely pubescent; stamens, with short slender filaments and 

 oblong apiculate anthers; ovary nearly inclosed in the calyx, shorter than the nearly sessile 

 lobes of the stigma. Fruit ripening in September, on slender villose pedicels, in large many- 

 fruited clusters, oblong-obovate to elliptic, surrounded at base by the enlarged deeply di- 

 vided calyx, rarely more than f ' long and I' wide, the wing terminal, rounded and often 

 emarginate or acute at apex, shorter than the terete many-rayed clavate body attenuate at 

 base and iV I' in length. 



A slender tree, 25-30, rarely 40-50 high, with a trunk 12'-18' in diameter, stout often 

 spreading branches forming a round-topped head, and slender terete branchlets coated 

 during their first season with hoary tomentum, and ashy gray, glabrous and marked by 

 large obcordate dark leaf-scars in their second year. Winter-buds: terminal acute, f 

 long, with 3 pairs of broad-ovate pointed tomentose scales, those of the inner pair strap- 

 shaped and \' long when fully grown. Bark of the trunk \'-\' thick, gray slightly tinged 

 with red, and deeply divided into broad flat broken ridges separating on the surface into 

 small thin scales. Wood heavy, rather soft, not strong, close-grained, light brown, with 

 thick lighter colored sapwood; used locally for axe-handles and in the manufacture of 

 wagons. 



Distribution. Mountain canons up to altitudes of 6000, central and southern Arizona 

 and southern New Mexico. Passing into the following varieties: var. coriacea Rehd. 

 (Fraxinus coriacea S. Wats.) differing in its thicker more coriaceous often more coarsely 

 serrate leaflets and in the less densely pubescent or glabrescent branchlets; southern Utah 

 (St. George, Washington County) to southeastern California; var. glabra Rehd. with 

 glabrous 3-7-foliolate leaves and glabrous branchlets; common with the species; occasion- 

 ally cultivated in the cities of Arizona; more distinct is 



Fraxinus velutina var. Toumeyi Rehd. 

 Fraxinus Toumeyi Britt. 



Leaves 3|'-6' long, with a villose-pubescent petiole, and 5-7 lanceolate to elliptic or 

 rarely obovate acuminate and long-pointed or acute leaflets, finely serrate above the mid- 

 dle x glabrous on the upper surface, covered on the lower surface with close fine pubescence,

1 2 '-3' long and |'-1' wide; petiolules slender, pubescent, \'-\' or that of the terminal leaflet 

 up to 1' in length ; occasionally on vigorous shoots reduced to a single leaflet. Flowers as in
