I have seen no specimens besides the type that could be referred here. The 
plant differs from A, sa/sa, which it most resembles, in its nar- 
rower, lanceolate leaves, more densely leafy stem, smaller bracts, 
and slightly different fruit. 
The type is from Salt Lake City, Utah, 1879, Jones 1887, 
Fig. 62.—Fruit 37. Abronia nealleyi Standley, sp. nov. Pratt XLII, Ficurr 1. 
ot Abronia Perennial: stems erect, branching from the base, 15 em, high, 
Sallac. Seale rather densely puberulent throughout; leaf blades thick, lanceo- 
*- late or narrowly elliptical, 20 to 25 mm. long and 5 to 9 mm, wide, 
rather obtuse at the apex, cuneate at the base, glabrous except the veins, these 
puberulent; petioles as long as the blades or shorter; peduncles 25 to 45 mui. 
long, densely puberulent; bracts scarious, broadly ovate, acute, 4 to 6 min. long 
and 3 mm. wide; flowers 12 mm. long, numerous, their tubes puberulent; fruit 
biturbinate, broadest about one-third below the sununit, 4 mm. long and almost 
as wide, narrowly ridged. 
This is a very distinct species because of its small bracts, harrow leaves, sinall 
fruit and flowers, and low habit; the plant appears to be vigorous and not at 
all like a depauperate form. Type in the herbarium of the Missouri Botanical 
Garden, collected at Screw Bean, Reeves County, Texas, in 1893, by G. C. Nea l- 
ley. In the National Herbarium there is another plant, collected October, ISS1, 
in Texas by Havard, that should probably be placed here. One collected by 
Havard at Odessa Tank, September, 1881, with the habit and general appearance 
of A. nealleyi, but the fruit with prominent wings and not biturbinate, is prob- 
ably of an undescribed species, but the material is insufficient for determination,

Perennial: stems slender, ascending; plant rather more leafy than A. fragrans, 
i. e., the internodes shorter; stems very sparingly puberulent, almost glabrous 
below; leaf blades ovate, obtuse or acutish at the apex, semicordate, truncate, 
or rounded at the base, glabrous; petioles mostly shorter than the blades, 
sparsely puberulent; peduncles slightly puberulent, 7 or S em, long: bracts 
elliptical, 6 or 7 mm. long and 4 mm. wide, acute; flowers mostly 15 mm. long; 
fruit biturbinate, about 7 mm. long and 8 mm, wide, with very narrow wings 
or ridges, these widest a little above the middle; outer fruits more strongly 
biturbinate than the inner ones; minutely puberulent above.
