16. Allionia brandegei Standley, sp. noy. 
Perennial from a very thick and woody root; stems many from each root, 
18 em. high or Jess, erect or spreading, viscid-pubescent throughout, densely so 
above; stems mostly simple, sometimes sparingly branched; leaf blades lanceo- 
late, 35 mm. long and 14 mm, wide or tess, thick, densely viscid-puberulent on 
both surfaces, attenuate toward the apex, cuneate or attenuate at the base; 
petioles one-half as long as the blades or usually less, those of the uppermost 
blades very short, densely viscid-pubescent; involucres few, axillary, not 
more than 1 at any single node, about 18 mm. in diameter and 10 mm. high, 
the bracts ovate or triangular-ovate, acute, longer than the tube, densely 
puberulent within and without, thick; fruit G mm. long, dark olive, acutish, 
with 4 or 5 low, more or less tuberculate ribs, the spaces between the ribs also 
tuberculate, very sparingly puberulent, some of the fruits even glabrous; 
flowers not seen but probably cleistogamous, 
This is most like A. pumila, but its leaves are thicker and more densely 
pubescent and of a different shape, the petioles shorter, and the lobes of the 
involucre more acute. Type in the herbarium of the University of California 
(no. 10164), collected in the Providence Mountains, California, June 2, 1902, 
Brandegee. Purpus’s 5905 from Highland Peak, Nevada, seems to be a glabrate 
form of this: aside from its less abundant pubescence it does not seem to 
differ, and is probably merely an older plant. 
17. Allionia pachyphylla Standley, sp. nov. 
Low, 30 em. high or less, from a woody root; stems stout, much branched, 
with short internodes, low and more or Jess spreading; stems with abundant, 
‘ather hispid pubescence throughout; leaf blades ovate, obtuse, truncate, or 
subcordate at the base or sometimes attenuate, thick, more or less puberulent 
on both surfaces, paler beneath; petioles of the lowest leaves almost as long 
as the blades, becoming shorter above, the uppermost leaves almost sessile, 
the petioles stout; inflorescence subcymose, of few branches, the branches 
with conspicuous, broadly ovate, thick bracts, densely pubescent; involucres 
on short, densely pubescent pedicels, about 1 cm. in diameter, their lobes 
ovate and densely pubescent; fruit 5 mm. long, acutish above, prominently 
5-ribbed, very finely puberulent. 
A very distinct species referred to A. pilosa (Gray), from which it is quite 
different in habit; its leaves, too, are much thicker, and the fruit more acute.

18. Allionia polytricha Standley, sp. nov. 
Krect from a rather thick and woody root; stems sparingly branched, stout, 
hirsute below, the branches of the inflorescence soft-pubescent; leaf blades 
ovate, the uppermost rather narrowly so, thick, glabrous or sparingly pilose, 
obtuse or rounded at the apex, rounded or truncate at the base, large, 7 em. 
long and 5 cm. wide or less: petioles stout, those of the lowest leaves one-third 
as long as the blades, the uppermost leaves sessile: inflorescence sparingly 
dichotomous-branched, the branches with numerous bract-like, much reduced, 
thick, puberulent leaves; involucres short-pediceled or almost sessile, about 10 
mm. wide, the bracts thick, broadly ovate, obtuse, 6 mm, high, more or less
