136 POLEMONIACE^. Collomia. 



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

 divisions, very numerous, all alternate: inflorescence thyrsiform or panicled: corolla salverform, 

 with tube little 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 very 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. 247 ; Gray, 1. c. 260. Phlox piiwata, Cav. Ic. t. 528. Cantua

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. I.e. 201. 

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



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 unequally 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. Cai/tuu loni/i flora, Torr. in 

 Ann. Lye. N. Y. ii. 221. G'dia longijlora, Don, Benth., &c. W. Nebraska and Colorado to 

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



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

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

 glabrous, branching into an effuse panicle : leaves 6 t 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.

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

 shape like that of Gilia tenul/lora. 



3. LCESELIA, L. (John Lcesel, 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 Gitia, 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. tenuifolia, 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-funnelform, 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. Cantillas 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
