Similar to the preceding species; leaves pubes- 
cent or glabrous, less imbricated, sometimes 
spreading, rigid, usually fascicled at the nodes, 
4-12” long. Flowers solitary and sessile or 
short-pedicelled at the ends of the branches, 
5-8” long; calyx-teeth narrowly lanceolate, 
acuminate, about equalling the tube; tube of the 
purple or white corolla longer than the calyx, its 
lobes obovate, entire. 
Dry soil, Nebraska and Montana to Utah, Cali- 
fornia and British Columbia, May-July. 
2. MICROSTERIS Greene, Pittonia 3: 300. 1808. 
Much-branched annual herbs, with entire leaves, all but the floral ones opposite, the small 
flowers solitary or in pairs in the upper axils. Calyx mostly campanulate, 5-cleft, scarious 
between the lobes. Corolla salverform, with a slender tube and a 5-lobed limb. Stamens 
short. Ovary 3-celled. Capsule at length distending and rupturing the calyx-tube. Seeds 
few and large, mucilaginous when wetted, but not emitting spiral tubes. [Greek, small Steris.] 
About 6 species, of western North America. Type species: Microsteris gracilis (Dougl.) Greene.

J Ly M, micrantha Greene, Pittonia 3: 303. 1898. 
LZ Annual, pubescent, at length corymbosely much 
branched, 2-6’ high, the branches ascending. Lower 
and basal leaves oblong to spatulate, obtuse, com- 
monly opposite and nearly sessile, the upper linear 
or lanceolate, sessile, #’-1’ long, 1”-2” wide, opposite 
or alternate, entire; cymes 1-5-flowered; calyx-lobes 
linear-subulate, usually longer than the tube; corolla 
about 4” long, the tube yellowish, narrow, equalling 
or slightly longer than the calyx, the lobes purple or 
violet, short; ovules 2 or 3 in each cavity; capsule 
oblong, obtuse, as long as or longer than the calyx- 
tube. ; 
In dry or moist soil, western Nebraska to Wyoming, 
Colorado, New Mexico, Arizona and California. In our 
first edition referred to the northwestern M. gracilis 
(Dougl.) Greene. April-Aug. 
3. GILIA R. & P. Prodr. Fl. Per. 47. 1708. 
Herbs with opposite or alternate, entire pinnatifid palmatifid or dissected leaves. Flowers 
small or large, solitary, cymose, capitate, thyrsoid, or paniculate. Calyx campanulate or 
tubular, 5-toothed or 5-cleft, the sinuses scarious. Corolla funnelform, tubular, campanulate, 
rotate or salverform, 5-lobed, the lobes ovate, oblong, or obovate. Stamens equally or 
unequally inserted on the corolla, included or exserted. Ovary oblong or ovoid, 3-celled; 
ovules solitary or several in each cavity. Capsule ovoid or oblong, 3-celled, at length dis- 
tending and rupturing the calyx. Seed-coat commonly mucilaginous when wetted, in some 
species emitting thread-like tubes. [Named for Philip Gil, a Spanish botanist.] 
About 100 species, natives of America. Besides the following, many others occur in the south- 
ern and western parts of North America. Type species: Gilia laciniata R. & P. 
Corolla funnel-form to salverform; leaves pinnatifid or pinnately divided, the segments linear, not 
meee thyrsoid-paniculate or corymbose-paniculate, 
Corolla 1’-2’ long; plants 1°-4° tall. 
Flowers paniculate, white. 1. G. longiflora, 
Flowers narrowly thyrsoid, red. 2. G. aggregata,
