STANDLEY—ALLIONIACEAE OF THE UNITED STATES. 865 
The following plants differ from the typical form in being almost glabrous: 
CALIFORNIA: San Diego, 1902, Brandegee 826; Santa Inez Mountains, 1888, 
Brandcgec; Santa Barbara, 1902, Elmer 3764; Elysian Hills, Los An- 
geles County, 1902, Braunton 162; Los Angeles, 1904, Grant 791. 
A plant in the herbarium of Nevada State University collected at Highlands, 
San Bernardino County, California, 1904, by N. KX. Berg, is an interesting form 
with long-petioled leaves which are rounded and cordate at the base and some- 
times reniform in outline, and with stout, suffrutescent stem. 
7a. Hesperonia californica microphylla Standley, subsp. nov. 
Much branched from 2 woody base, the lower branches woody and whitish, 
glabrous, the internodes short, the nodes large and swollen; leaf blades irreg- 
ularly ovate or deltoid-ovate, obtuse or acutish, mostly semicordate at the base, 
thick, 15 mm. long and 8 mm. wide or usually less; petioles about half as long 
as the blades; branches of the inflorescence slender, not much branched, 2 or 
sometimes more flowers at each node, the flowers on short pedicels which are 
sparingly scabrate; flowers about 11 mm. long; stamens included; bracts 4 or 
5 mm. long, the free portion rather narrowly triangular, acute, a little longer 
than the tube or as long; fruit elliptical in outline, 4 mm. or less in length, 
dark brown. 
Type in the herbarium of the University of California (no. 101214), collected 
by Brandegee on San Martin Island, Lower Californin, Mareh 12, 1897. Also 
collected by the same collector at Ensenada, Lower California, April 26, 1893. 
The small leaves and flowers, whitish stems, and dense habit distinguish the 
subspecies, 
8. Hesperonia glutinosa (A. Nelson) Standley. 
Mirabilis glutinosa A. Nelson, Proc. Biol. Soc. Wash. 17: 92. 1904. 
Specimens exramined: 
NEVADA: Karshaw, Meadow Valley Wash, 1902, Goodding 967, type; Hum- 
boldt County, 1865, Torrey; Virginia Mountains, 1867, Watson 963. 
8a. Hesperonia glutinosa retrorsa (Heller) Standley. 
Mirabilis retrorsa Heller, Muhlenbergia 2: 198. 1906. 
I can not see how this can be separated from HH. glutinosa except as a sub- 
species. It differs from that species in having narrower and more acute leaves 
and less abundantly pubescent stem; but aside from these minor differences I 
ean see little to separate the two plants. 
Specimens examined: 
CALIFORNIA: Near Southern Belle Mine, Mono County, 1906, Heller 8836, 
type; near Victorville, 1905, Hall 6206; Sierra Nevada Mountains, 1875, 
Lemmon; Colorado Desert, 1905, Brandegec; Antelope Valley, 1896, 
Davy 2294. 
NeEvADA: Reno, 1895, I’. G. Hillman; Pah Ute Mountains, 1868, Watson 963; 
Pyramid Lake, 1908, G. H. True 758; Truckee Pass, Virginia Moun- 
tains, 1905, Kennedy 727; Truckee Pass, 1907, Kennedy 1595; Mica 
Spring, 1894, Jones 5045a. 
The following are doubtfully referred here: 
CaLiForRNIA: San Felipe Canyon, Colorado Desert, 1901, Brandegee; east 
slope of Walker Pass, 1891, Coville & Funston 1018; Ralston Desert, 
1891, Coville & Funston 1996. 
8b. Hesperonia glutinosa gracilis Standley, subsp. nov. 
Stems very slender, more or less villous throughout, especially above, not 
viscid or inconspicuously so, not much branched except near the base; inter-
