§ 3, Leptosiphon, Endl., Beiitb. Corolla salverform, with the tube mostly 

 filiform and elongated ; the very short throat commonly abruptly more or less 

 cyathiform-dilated : stamens inserted in the throat or orifice : anthers short : 

 ovules numerous : annuals, mostly low or slender, with opposite narrow leaves, 

 and handsome but commonly small flowers crowded into a capitate leafy-bracted 

 cluster, (Style either very long and more or less exserted, or rather rarely short 

 and included, in difi^erent individuals of the same species.) — Leptosiphon, Benth. 



* Palmately-leaved genuine species, hairy, leafy-stemmed; commonly with leaves fascicled in the 

 axils and all 5-7-parted; their divisions linear-tiliform : filaments slender, exserted more or less 

 from the throat of the corolla, shorter than its entire lobes : ovules 6 to 10 in each cell. 



•1^ Large-flowered, and the tube of the corolla only equalling or little exceeding the obovate lobes. 



G. densiflora, Benth. Bather stout and large, often strict : numerous divisions of the 

 loaves filiform, somewhat rigid : tube of the lilac or nearly white corolla (half inch long) 

 little if at all exserted beyond the calyx, and villous-hirsute bracts. — Gray, Proc. 1. c. 

 Leptosiphon densiflorus, Benth. in Hort. Trans, viii. t. 18 ; Lindl. Bot. Reg. t. 1725 ; Hook. 

 Bot. Mag. t. 3578. GiUa Leptosiphon, Steud. Nom. Varies with corolla-tube a little more 

 exserted, when it is G. fjrandljiora, Steud. & Benth. 1. c. and Leptosiphon (jrandijiorus, Benth. 

 in Bot. Reg. — California ; common towards the coast. 



•*- -f— Slender-flowered; the filiform tube of the corolla 2 to 6 times the length of the lobes; these 

 from 4 to less than 2 lines long, oval or ovate. Species difficult to define. 



G. brevicula, Gray. A span high, corymbosely branched, minutely pubescent and 

 above glandular : leaves few and short (quarter of an inch long) : tube of the corolla only 

 5 or 6 lines long, but much exceeding the calyx and bracts, hardly twice the length of 

 the (purple or violet) lobes: otherwise much like the next. — Proc. Am. Acad. xii. 79. — 

 Southeastern California, on the Mohave River, Palmer. 



G. androsacea, Steud. A span to a foot high : corolla much exserted beyond the 

 hirsute or villous-ciliate bracts and subtending leaves, hiac, pink, or nearly white with yel- 

 low or dark throat; its tube an inch or less long, thrice the length of the lobes (limb 8 to 

 10 lines in diameter). — Gray, 1. c. & Bot. Calif, i. 491. LeptosijJton androsaceus, Benth. iu 

 Hort. Trans, viii. t. 18; Hook. Bot. Mag. t. 3491; Lindl. Bot. Reg. t. 1710. — California; 

 common west of the Sierra Nevada. 



Var. rosacea, Gray. A dwarf and tufted form, with rose-red corolla, varying 

 however into other hues. — Bot. Calif. 1. c. Leptosiphon parvljiorus, var. rosaceus, Hook, 

 f. Bot. Mag. t. 5863. — Near San Francisco, Kellogg. 



Var. detonsa, Gray, 1. c. Slender and almost glabrous form, the bracts and leaves 

 merely hispidulous-ciliate. — Western part of California, Bridges, Brewer. A less marked 

 form occurs on the borders of Nevada, Anderson. 



G. raicrantha, Steud. Slender, a span or so high : tvibe of the corolla extremely 

 slender, three-fourths to inch and a half long, 4 to times longer than the lobes ; these 2 or 

 3 lines long: pubescence of the bracts, &c., short and soft, rarely hirsute-ciliate. — Gray, 

 Proc. 1. c. excl. syn. var. rosaceus, Bot. Mag. Leptosiphon pnrvijlorns & L. Inteits, Benth. in 

 Bot. Reg. GiUa micranfha & G. liitaa, Benth. in DC. 1. c. — California ; common through 

 the western part of the State. Flower from purplish or lilac to cream-color, suliihur-yel- 

 low, and even golden yellow (var. atirea, Benth. PI. Hartw.). 



Var. longitliba {G. hngituha, Benth. PI. Hartw. 324) is one of the larger-flowered 

 forms, apparently passing into G. androsacea. — Monterey, Hartweg, &c. 



G. tenella, Benth. Mostly depressed, small : tube of the corolla less slender in propor- 

 tion to the size of the lind) (0 to 9 lines long, the lobes only 11) : bracts and leaves hispidu- 

 lous-ciliate. — PL Hartw. 325. Leptosiphon 6/'co/or, Nutt. PL Gamb., chiefly. — Puget Sound 

 to Santa Barbara, California. Has been confounded with the two foregoing. Corolla dull 

 purple, or pink, with yellow throat. 



G. ciliata, Benth. Rigid, rough, 4 to 12 inches high, the taller stems virgate : tube of 

 the corolla slightly or not at all exserted beyond the very hirsute or hispid-ciliate bracts 

 and subtending leaves (6 to 9 lines, and the lobes only li lines long) : calyx-lobes acerose. 

 — PL Hartw. 1. c. ; Gray, I. c. — California, reaching into Nevada, &c. Greyish with short 

 pubescence on the stems, and longer both rigid and softer spreading hairs fringing the
