456 POLEMONIACE LINANTHUS 
NAVARRETIA 
much longer than the bracts and calyx, abruptly widened into the obconic 
throat and oblong obtuse lobes: flowers purple to pink or straw-color; with 
yellow throat. Common on dry open hillsides, Puget Sound to California, 
L. ciliatus Greene 1. c. 260. Gilia ciliata Benth. Rough-pubescent 
throughout: stem rigid, 4-12 inches high, virgate: divisions of the leaves 
acerose, 2-8 lines long: tube of the calyx cylindraceous, half as long as the 
subulate pungent lobes: tube of the corolla filiform, 4-6 lines long, but 
little if any longer than the hispid-ciliate bracts and calyx: throat of the 
corolla funnelform, yellow, nearly as long as the oblong rounded lobes. 
In groves, southern Oregon to California. 
* * Wholly glabrous: very dwarf: leaves entire: anthers sessile in 
the throat of the corolla, the cuneate lobes of which are sometimes un- 
dulate-toothed or 1-3-dentate at the apex: ovules 10-16 in each cell. 
L. nudicaule. Gilia nudicaulis Gray. Very glabrous: stem 1-10 
inches high, at length branching from the base, leafless from the cotyle- 
dons to the inflorescence which is a close head or glomerule subtended by 
an involucre of several ovate-Janceolate or lanceolate foliaceous bracts: 
corolla white, pink or yellow; the tube 3-4 lines long, about 3 times as 
long as the calyx, rather longer than the lobes. Sandy plains, interior of 
Oregon to Nevada and Colorado. 
5 NAVARRETIA Ruiz & Pavon Prodr. Fl. Per. et Chil. 20. 
Low annuals with alternate pinnatifid leaves and small flowers 
in leafy-bracted capitate clusters. Tube of the calyx scarious be- 
tween the 5 prominent green angles or costa, its lobes unequal, 
erect or spreading, pungent tipped, all entire, or the 2 larger ones 
spinulose-toothed or cleft. Corolla tubular-funnelform or almost 
salverform, with rather small oval or oblong lobes. Stamens in- 
serted in or below the throat: anthers short. Capsule dehiscent 
from above or from below, or indehiscent. Seeds one to many in 
each cell, mostly mucilaginous and developing spiral threads 
when wetted. 
* Some of the leaves and bracts more than once pinnately parted, 
that is their primary divisions incised or parted. 
+ Herbage very glandular-viscid and unpleasantly aromatic- 
scented: stamens included in the throat of the corolla, commonly 
unequal in length and slightly so in insertion: ovules and seeds 8-12 
in each cell: 
N. squarrosa H. & A: Bot. Beech. 368. Gilia squarrosa Gray. Very 
glandular-viscid: stem rather stout and rigid, 3-12 inches high, simple or 
much branched: leaves twice pinnatifid, or pinnately parted and the divi- 
sions either pasted or incised; upper ones and bracts spinescent: lobes of 
the calyx subulate and spinescent-tipped, mostly entire, longer than the 
tube: corolla blue to whitish, 4-6 lines long, with slender tube and funnel- 
form throat, but little surpassing the calyx: capsule ellipsoid, inclined to 
be stipitate. Common on plains and along roadsides, western California 
and Oregon to Brit. Columbia. 
+ + Herbage neither. viscid nor glandular: stamens exserted out 
of the throat of the corolla, at length mostly equalling the lobes: ovules 
1-4 in each cell. | 
N. stricta. Stem strict, 4-6 inches high, divaricately branched above: 
leaves few, bipinnate, the divisions all spinose: bracts similar to the leaves,
