N4VARRETIA 



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-lanceolate 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 Ohil. 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 : 



X. 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 parted 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,
