496 POLEMONIACE.E. Gilia. 



* Perennial, densely-flowered. 



32. G-. congesta, Hook. Woolly-pubescent, becoming glabrate, tufted, 3 to 12 

 inches high : leaves petioled, much crowded on the short sterile shoots, scattered on 

 the erect flowering stem, thickish, mostly pinnately parted into 3 to 7 short-linear 

 or oblanceolate divisions, which are not rarely so crowded as to appear palmate or 

 pedate : flowers numerous in solitary or a few corymbose naked and dense heads : 

 corolla white ; its tube hardly longer than the calyx and the oval lobes (these a line 

 or two long) : exserted h'laments as long as the anthers : ovules 2 to 4 in each cell. 

 Fl. ii. 75, &Ic. PI. t. 235. 



Sierra Nevada at 10,000 feet and upwards, in Placer and Nevada Counties (Brewer, Bolander, 

 E. L. Greene), and on the northern border of the State (Newberry) : thence to Oregon and the 

 Rocky Mountains. The var. crcbrifolia, Gray (G. crcbrifolia, Nutt.), with entire and more 

 glabrous leaves, occurs in the northeastern part of Nevada. 



* * Annual, low and spreading, loosely branched : flowers fewer, more leafy-graded, 

 in less dense clusters : lobes of the calyx and leaves conspicuously cuspidate-tipped. 



33. Gr. pumila, Nutt. Slightly woolly-pubescent : leaves narrowly linear, en- 

 tire or with 2 to 4 narrow lobes : tube of the corolla (3 or 4 lines long) about twice 

 the length of its lobes and of the calyx-lobes : filaments shorter than the lobes of 

 the corolla : ovules 5 or 6 in each cell. PL Gamb. 156. G. trifida, Benth. in 

 Kew Jour. Bot. iii. 291. 



Foot-hills of the Truckee Mountains, Northwestern Nevada, Watson. Thence east to New 

 Mexico and Wyoming. 



34. Gr. polycladon, Torr. Puberulent or sparsely pubescent, with elongated 

 branches leafless below : leaves short, spatulate or oblong in outline, incisely pin- 

 natifid into several small and irregular lobes ; those of the branches mainly clustered 

 around the flowers (half an inch long) : corolla barely 2 lines long, its tube hardly 

 exceeding the calyx-lobes : anthers almost sessile in the throat : ovules only a pair 

 in each cell. Bot. Mex. Bound. 147; Watson, Bot. King Exp. 268. 



Mountains on the western borders of Nevada, Watson. Thence east to Utah and the borders 

 of Texas. This and the preceding will doubtless be detected within the State. 



9. Flowers thyrsoid-panided, hardly bracteate: corolla (red] salverform with a long 

 and slightly funnelform tube, very much surpassing the calyx: stamens inserted 

 in or below the throat of the corolla, not longer than its lobes : anthers short : 

 ovules numerous in each cell: biennials, merely pubescent, with simple virgate 

 stem and large showy blossoms. IPOMOPSIS, Benth. 



35. G-. aggregata, Spreng. A foot to a yard high : leaves thickish, pinnately 

 parted into 7 to 1 3 linear mucronulate divisions, or in the upper leaves fewer : 

 flowers in small clusters, disposed in a simple or sometimes branching virgate naked 

 panicle : calyx commonly glandular ; its lobes subulate : corolla scarlet (varying to 

 pink or rarely white) ; its tube an inch long, 2 to 4 times the length of the ovate- 

 lanceolate or oblong-lanceolate acute soon recurved-spreading lobes : filaments slen- 

 der. Don, Brit. Fl. Gard. ser. 2, t. 218 (Cantua aggregata, Pursh). G. jmlchella, 

 Dougl. in Hook. Fl. ii. 74. Ipomopsis elegans, Lindl. Bot. Reg. t. 1281. Runs 

 into various forms, of which the most marked is 



Var. Bridges!!, Gray, 1. c. : a rather low form, loosely somewhat few-flowered : 

 corolla said to be purple : calyx-lobes short and broadly triangular-subulate or ovate- 

 deltoid : lobes of the leaves very obtuse, seldom mucronulate. 



Rocky ravines, &c. , Sierra Nevada, throughout its length, to Oregon and Idaho, and east to the 

 Rocky Mountains. The variety collected only by Bridyes, station in California unknown, but 

 various specimens of the Sierra Nevada approach it. Flowers "very fragrant," even more showy 

 than those of the related G. coronopifolin of the Southern Atlantic States. Stamens in some in- 

 dividuals included, in others conspicuously exserted ; these with style equally or even more 

 exserted.
