14. Allionia ciliata Standley, sp. nov. 
Orybaphus aggregatus Torr. Bot. Mex. Bound. 168, 1858, not Vahl. 
Plant low, 20 cm. high, erect, abundantly dichotomous-branched, especially 
near the base; stems angled, at least when dry, glabrous below, with a few 
scattered, weak hairs above; leaf blades linear-lanceolate, thin, blunt-pointed, 
rounded, cuneate, or attenuate at the base, the margins very irregular and with 
a few conspicuous long, soft, white hairs, a few such hairs seattered over the 
surfaces of the leaves as well; petioles 7 mm. long or less, with a few hairs 
like those on the blades; inflorescence axillary or a few of the involucres 
clustered at the ends of the branches; involucres short-pediceled, the pedicels 
rather densely long-pubescent, not at all viscid: involucres about 10> mm. 
wide and 8 or 9 mm. high, the lobes about as long as the tube, acutish, sparingly 
puberulent or glabrous, ciliolate-margined; fruit + mim. long, brown, rather 
obtuse above, slightly narrowed below, 5-ribbed, the ribs thick and more or 
less tuberculate, the narrow spaces between them also tuberculate, glabrous. 
The plant in habit suggests A, brandegei or A. pumila, but its almost 
glabrous stem and different pubescence at once distinguish it. Type U. S. 
National Herbarium no, 22690, cotype in the herbarium of the Missouri Bo 
tanical Garden; collected at Smith’s Run, western Texas, 1851-52, Wright 1717 
The specific name above adopted was used by Professor Heimer] in her 
barium under Mirabilis. 
15, Allionia pumila Standley, sp. nov. 
Plant low, about 12 cm. high, much branched from a thick, woody root, the 
stems sparingly branched: stems rather slender, densely soft-pubescent; leaf 
blades ovate or oblong, small, 25 mm. long and 16 mm. wide or less, obtuse 
or rounded at the apex, rounded or mostly somewhat attenuate at the base, 
rather thick but soft, finely puberulent on both surfaces, yellowish-green : peti- 
oles slender, pubescent, mostly as long as the blades or longer, some of the upper- 
most a little shorter: involucres solitary in the axils of the leaves, drooping on 
short, densely pubescent pedicels; bracts ovate, obtuse, densely soft-pubescent, 
10 mm. or less in diameter, about 5 to 6 mm. high; fruit not seen, 
A very distinet species on account of its low, dense habit, finely pubescent 
stems, and long petioles. It is as closely related to A. aggregata as to any 
species, but is different in habit and pubescence. Doctor Heimer! in the National 
Herbarium has labeled it A. pilosa (A. Gray) (A. comata Small), but the 
latter is a much larger plant with quite different inflorescence. Type U. 8.
