fruit about 4.5 mm. long, obtuse above, cousiderably narrowed below, with 
wide, smooth ribs, the narrow spaces between the ribs tuberculate, puberulent. 
The differently formed fruit. pubescent leaves, and more pubescent involueres 
separate this plant from A. bodini. Type in the herbarium of Field Museum 
of Natural History (no, 161591), collected at El Paso, Tex., 1881, Vasey.

1. Allionia pinetorum Standley, sp. nov. 
Perennial from a thick, fleshy root about 18 mm. thick or less; stems few 
from each root, rarely more than 2. 35 cm. or less in height, very slender, sim- 
ple or very sparingly branched, glabrous below, very minutely soft-puberulent 
above; leaves sessile, narrowly linear, thin, 65 mm, long and 3 mm. wide or 
less, sharp-pointed, glabrous, divaricate or asc ending; inflorescence axillary or 
of small, loose, terminal, few-flowered cymes; involucres on pubescent pedicels & 
mm. long or less; upper leaves sometimes reduced to bracts; involucres 8 min. 
wide and 6 mm. high or less, the lobes elliptical or oblong, obtuse, rather densely 
soft-puberulent: flowers apparently all cleistogamous: fruit 3.5 mm. long, in- 
conspicuously 5-angled, very minutely and sparingly hispidulous. 
This is perhaps as closely related to 4. bodini as to any species. but it is 
# much more slender, less branched plant, its leaves narrower and thinner. 
Type collected at Gilmodre’s Ranch, on Eagle Creek, White Mountains, New 
Mexico, August, 1907, Wooton & Standley 8896, growing on a rather dry hill-
