136 POLEMOXIACEiE. ^Collomia. 



* Cauline leaves simply pinnatelj' parted into few (3 to 7) narrow-linear or often almost filiform 



di\isious, very numerous, all alternate : inflorescence thyrsiform or panicled : corolla salverform, 



with tube littfe if at all dilated upward. 



C. Cavanillesiana, Don. Biennial (or perhaps perennial southward) with a somewhat 



woody base, more or less pubescent, virgately branched : flowers in small clusters in a 



narrow or raceme-like leafy thyrsus : pedicels verj^ short or none : corolla white, ochroleu- 



cous, or tinged with purple, only half inch long ; the tube 2 or 3 times the length of the 



calyx ; the sinuses somewhat unequal ; lobes oblong : filaments moderately unequally 



inserted high in the considerably funnelform-expanded throat : anthers roundish : ovules 



5 to 7 in the cells. — Syst. iv. 246 ; Gray, 1. c. 260. Phlox pinnata, Cav. Ic. t. 628. Caritua

 PI. Gamb. 1. c. — New Mexico and W. Texas to Arizona. (Mex.) 



C. Thurberi, Gray. Resembles the preceding in foliage and growth, but only minutely 

 pubescent : inflorescence more spicate : flowers much larger : corolla blue or lilac, showy, 

 salverform ; the tube an inch or rather more in length, very slightly and gradually dilated 

 upwards, 3 or 4 times the length of the calyx and of its orbicular lobes : filaments in the 

 throat: anthers short-oblong; ovules 8 or 9 in each cell. — Proc. Am. Acad. 1. c. 261. — 

 New Mexico, near the Santa Rita coppermines, and in Arizona, Thurher. 



C. longiflora, Gray, 1. c. Annual, glabrous, loosely paniculate-branched : divisions of 

 the leaves long and slender : flowers loosely somewhat corymbose on slender peduncles : 

 corolla white, strictly salverform and Phlox-like, showy ; the tube often an inch and a 

 half long, with narrow orifice; lobes orbicular or ovate (sometimes abruptly pointed): 

 filaments very \mequally inserted into the upper part of the tube, or 2 or 3 of them in the 

 throat : anthers elongated-oblong : ovules 10 or 12 in each cell. — Cantua longiflora, Torr. in 

 Ann. Lye. N. Y. ii. 221. Gilia longiflora, Don, Benth., &c. — AV. Nebraska and Colorado to 

 borders of Texas, and Arizona ; common in pine forests. 



* * Leaves mostly entire, narrowly linear, scattered: corolla truly funnelform. 



C. leptalea, Gray. Slender annual, 2 to 18 inches high, minutely glandular, otherwise 

 glabrous, branchmg into an effuse panicle : leaves 6 to 20 lines long, or the uppermost 

 reduced to small subulate bracts, the lower sometimes with 2 or 3 small lobes : peduncles 

 filiform or capillary : calyx small ; its lobes subulate : corolla pink-red, 5 to 10 lines long ; 

 its slender tube longer than the calyx, and rather abruptly expanded into a wide funnel- 

 form throat of about the length of the oval spreading lobes. — Proc. Am. Acad. I.e. 



6 Bot. Calif, i. 488. Gilia capillaris, Kellogg in Proc. Calif. Acad. v. 46. — California ; com- 

 mon on moist or wet banks in the Sierra Nevada, &c. A delicate species ; the corolla in 

 shape like that of Gilia tenuiflora. 



3. LCESifiLiIA, L. (John Lossel, of the 16th century, author of a Flora 

 Prussica, &c.) — Somewhat shrubby or suffruticulose plants (of Mexico and ad- 

 jacent districts) ; with more or less rigid and commonly spinulose-toothed or 

 spinulose-ciliate leaves, and the uppermost forming conspicuous bracts to the 

 clustered flowers. But the following species form a section, Giliopsis, connect- 

 ing with Gilia, having more scattered flowers, hardly any bracts, and very nar- 

 row leaves (all alternate), merely with rigidly mucronate tips. Limb of the 

 corolla irregular by one of the lobes being separated by deeper sinuses from the 

 others ; the cuneate lobes erosely truncate or 3-denticulate : filaments incurved 

 below the apex. — Gray, Proc. Am. Acad. xi. 86. 



L. tenuif olia, Gray. Much branched from a somewhat woody perennial base, a span to 

 a foot high, nearly glabrous : leaves linear-acerose, entire, or the lower and larger with 2 or 

 3 spreading subulate lobes : flowers rather crowded at the summit, the branches short-pedi- 

 celled : calyx-lobes subulate : corolla bright red, narrowly tubular-f unnelform, an inch long ; 

 the tube 3 or 4 times the length of the lobes : capillary filaments and style conspicuously 

 exserted: ovules 8 or 10 in each cell. — Bot. Calif, i. 500, & Proc. 1. c — Tantillas Moun- 

 tains, on the lower border of San Diego Co., California, Mr. Dunn, Palmer. 

 L. effusa, Gray. Diffusely much branched and rigid from an apparently annual root, 

 a foot high, nearly glabrous : leaves all entire and filiform or very narrowly linear, short
