146 POLEMONIACE^. Gilia. 



branches linear and subulate, bract-like, entire : flowers mainly pedicellate : calyx-lobes 

 subulate, shorter than the tube: corolla rose-red^ slender; the tube (half inch long) several 

 times longer than the obovate lobes : anthers subsessile in the throat : ovules only 6 in 

 each cell : seeds fewer, neither spirilhferous nor mucilaginous when wetted. — Proc. Am. 

 Acad. xii. 79. — S. W. Colorado or adjacent Utah, on the San Juan, Brandcgee. 



§ 10. Gilij(ndra, Gray. Flowers thyrsoid-paniculate and hardly bracted, 

 rather small : corolla bluish or white, salverform ; the tube hardly double the 

 length of the calyx and little longer than its own obovate lobes : these surpassed 

 by the slender and much exserted filaments : anthers short : ovules about 6 in 

 each cell : seeds destitute both of mucilage and spiricles : glandular-puberulent 

 and rather low biennials, with simply pinuatifid leaves, the radical in a dense 

 rosulate tuft : calyx-lobes triangular. ■ 



G. stenoth^sa, Gray. Stem simple, virgate, very leafy up to the racemiform narrow 

 thyrsus : leaves pinnately cleft into short oblong lobes : bracts small and entire : stamens 

 moderately exserted : corolla somewhat funnelform, apparently white, nearly half inch 

 long. — Proc. Am. Acad. viii. 276. — Uinta Mountains, Utah, Fremont. 



G. pinnatifida, Nutt. Stem simple or loosely branching, a span to 2 feet high : inflores- 

 cence open-paniculate, often compound : leaves pinnately parted into linear or narrowly 

 oblong lobes; these sometimes again 1-2-lobed; stamens conspicuously exserted (3 lines 

 long, inserted just uhder the sinuses): corolla strictly salverform, pale blue or violet, or 

 the narrow tube white (this and the lobes 2 or 3 lines long). — Gray, 1. c. — Rocky Moun- 

 tains, common from S. Wyoming through Colorado (and Utah ?) to New Mexico. 



§ 11. MiCROGiLiA, Benth. Flowers scattered, very small: corolla white, sal- 

 verform : stamens inserted on and included in the tube : ovules solitary in the 

 cells: much-branched annuals, with filiform or slender-subulate and entire (or 

 sometimes 3-parted) small leaves : calyx short-campanulate, 5-toothed. 



G. minutiflora, Benth. Glabrous, or minutely glandular-puberulent above : stem erect, 

 a foot or two high, with many virgate and rigid slender branches : upper leaves all reduced 

 to minute subulate appressed bracts ; tlie lower longer and some of them 3-parted : flowers 

 terminating and also sparsely spicately disposed along the branchlets, 2 lines long : tube of 

 the corolla about twice the length of the calyx and of its own lobes : filaments slender: 

 capsule oval: seed oblong. — DC. Prodr. ix. 315. Collomia (PicrocoUa) linoides, 'Nutt. F\. 

 Gamb. 159. — Interior of Oregon (or now Idaho, not " CaUf ornia "), Douglas. Wyoming 

 on the Upper Platte, Nuttall, Fremont. 



G. tenerrima, Gray. Minutely and sparsely glandular, low, effusely much branched : 

 branches filiform : leaves entire : flowers loosely panicled, on slender divergent pedicels, 

 minute: capsule globular (barely a line long): seed turgid oval. — Proc. Am. Acad. viii. 

 277 ; Watson, Bot. King, 270. — Utah, Bear River Valley, near Evanston (in fruit), Watson. 



§ 12. EuGiLiA, Benth., Gray. Flowers scattered, crowded, or rarely capitate- 

 glomerate, inconspicuously bracted or ebracteate : corolla from funnelform to 

 nearly rotate : stamens usually inserted in or just below the sinuses of the corolla, 

 not exceeding its lobes (or rarely moderately so) : filaments slender : leaves 

 various, all or chiefly alternate. 



* Ovules solitary in the cells: corolla funnelform with slender elongated tube and rather abruptly 

 dilated tliroat (in the manner of § Navarretici, but no pungent or even mucronate tips to calyx- 

 lobes or leaves): sinuses of calyx somewliat replicate : very depressed small perennials, with fih- 

 form rootstocks and crowded leaves, among which the violet or purplish flowers are solitary aud 

 subsessile in the forks or axils. 



G. Larseni, Gray. Filiform creeping rootstocks elongated: stems rising only an inch or 

 two above ground : leaves pedately 5-7-parted or the upper 3-oleft, rather surpassing tlie 

 flowers, soft-pubescent : corolla half inch long, with tube slightly exceeding the calyx ; its 

 rounded lobes somewhat surpassing the stamens and style. — Proc. Am. Acad. xi. 84, & Bot.
