3 COLLOMIA Nutt. Gen. i, 126. 
Annual or rarely perennial herbs. with mostly entire alternate 
leaves and purple white or yellow flowers in capitate clusters or 
cymes. Calyx obpyramidal, 5-cleft, scarious in the sinuses ac- 
crescent in fruit, not distended nor ruptured by the maturing cap- 
sule; its lobes erect and entire; the sinuses often at length enlarged 
into revolute lobes. Corolla tubular-funnelform or salverform: 
the limb 5-lobed. Stamens unequally inserted on the tube of the 
corolla: the filaments unequal. Ovules few or solitary in each 
cell. Seeds developing both mucilage and spiral threads when 
wetted. 
* Annuals with strict and leafy stems, entire or merely toothed leaves 
and numerous flowers in capitate-crowded terminal leafy clusters. 
C. grandiflora Dougl. Lindl. Bot. Reg. t. 1174. Stems erect, 6-20 0, ,,,..2L- 
inches high, simple or sparingly branched: leaves lanceolate to linear, 
entire or coarsely serrate, acute or acuminate, 1-3 inches long, sessile or 
nearly so: flowers yellow or salmon color, numerous in a dense capitate 
' leafy-bracted cluster: bracts broadly lanceolate to ovate: calyx somewhat 
‘funnelform, the triangular lobes about half as long as the tube, glandular: 
corolla nearly an inch long with a long filiform tube; the oblong lobes about 
as long as its funnelform throat: ovules solita:y in the cells. Common in 
open woods, California to Brit. Columbia and the Rocky Mountains. 
C. linearis Nutt. Gen. i, 126. Viscid-puberulent annual: stem erect, 
4-12 inches high, simple or branched: leaves narrowly lanceolate to linear- 
oblong, entire or few-toothed or few-lobed, acute at the apex, narrowed 
‘below, sessile, or the lower short-petioled, 1-2 inches long: flowers numer- 
ous, in a close capitate cluster, 5-7 lines long: calyx-lobes triangular-lan- 
-ceolate, acute: corolla purple to nearly white, with a very slender tube 
longer than the calyx and but little enlarged throat, the rounded lobes 1-2 
lines long: ovules solitary in the cells. Eastern Oregon to Brit. Columbia, 
Manitoba, Minnesota, Arizona and California. 
Var. subulata Gray Proc. Am. Acad. viii, 258, ‘‘ A low and slender 
form, diffusely branching from the base: leaves narrow and acute: flowers 
few in the lower forks: calyx-lobes attenuate-subulate, the tips almost 
awn-like from a broad hase, rather longer thanthe tube. Nevada and 
adjacent parts of California and Oregon. 
* * Annuals usually branching from the base, the flowers in nearly 
oF quite bractless small clusters in the axils and at the ends of the 
ranches.
