170 HYDROPHYLLACEJE. Phacelia. 



■H- Leaves deeply once or twice pinnatifid ; short fruiting pedicels erect : corolla half inch long : 

 pubescence minute, more or less viscid. 



~P. Premontii, Torr. 1. c. A span to a foot high, much branched from the tase: leaves 

 once pinnatifid into 7 to 15 oblong or obovate entire or obtusely 2-3-lobed divisions : flow- 

 ers crowded in the at length elongated spiciform raceme : corolla broadly funnelform, 

 double the length of the spatulate calyx-lobes ; the long and narrow appendages united 

 below with the filament or almost free from it : capsule oblong : seeds 20 to 30, strongly and 

 somewhat evenly corrugated. — Watson, Bot. King, 253 ; Gray, 1. c. — S. Utah and Nevada 

 to W. Arizona and Kern Co., California. 

 P. bicolor, Torr. Lower and more diffuse : leaves pinnately parted and the divisions 

 again irregularly pinnatifid into small nearly linear lobes : spiciform racemes loosely 10-20- 

 flowered : corolla narrowly funnelform (sometimes 7 lines long), thrice the length of the 

 narrowly linear and obscurely spatulate calyx-lobes ; the long and narrow appendages 

 united for more than half their length with the filament, forming a long tubular cavity 

 behind it : capsule oval-oblong : seeds about 16, shorter, minutely corrugated. — Watson, 

 Bot. King, 255 ; Gray, 1. u. — W. Nevada and adjacent parts of California in the Sierra 

 Nevada, first collected by Anderson. The handsomest of the section. 



++ ++ Leaves merely pinnatifid-dentate: corolla only 3 or 4 lines long. 



■ P. gymnoolada, Torr. Diffusely branched from the base, a span or less high, some- 

 what viscid-pubescent ; the primary branches decumbent and with long naked internodes : 

 leaves obovate or oblong, obtuse, coarsely and obtusely toothed (an inch or less long), 

 mostly shorter than the petiole : spike several-flowered : short-f unnelform corolla (rarely 

 white) not twice the lengtli of the linear or obscurely spatulate-hirsute calyx-lobes; its 

 appendages united with the lower part of the filament : capsule globose-ovate, 8-16-seeded. 

 — Watson, 1. c. ; Gray, 1. c. — W. Nevada and E. California, in the foothills of the Sierra 

 Nevada and Humboldt Mountains, Watson, Lemmon. 

 P. crassifolia, Torr. Diffusely branched from the base, 3 or 4 inches high, viscid- 

 pubescent: leaves somewhat fleshy, oblong-ovate, scabrous (3 to 6 lines long), tapering into 

 a short petiole ; the lower with a few short obtuse teeth ; the cauline entire : racemes 

 ra ther loosely few-flowered ; the short pedicels spreading : funnelform corolla fully twice 

 the length of the linear calyx-lobes ; the obscure appendages free from all but the very 

 base of the filament: capsule ovoid, 6-8-seeded. — Watson, Bot. King, 255. — Eeese River 

 Valley, Nevada, Watson. Seeds rather strongly rugose, oblong, half a line long. 



6. EMMENANTHE, Benth. (From fjwjusVra, I abide, and avdo?, flower, 

 the corolla persisting.) — Low annuals (of California and Nevada), with much 

 the habit and general character of certaili sections of Phacelia, but the yellow 

 or cream-colored campanulate corolla persistent (not carried off by the enlarging 

 capsule). — Gray, Proc. Am. Acad. a. 328, & Bot. Calif, i. 514. 



§ 1. MiLTiTZiA, Gray. Diffuse or depressed, and with the general characters 

 of Phacelia § Microgeneles, except the persistent corolla : flowers small : calyx- 

 lobes broader upward : seeds more or less rugose transversely or obliquely, as well 

 as minutely reticulated. — i/i'fei'tew, A.DC. Prodr. ix. 296. 



* Corolla bright yellow, merely 5-Iobed, exceeding or at lenst equallinp; the calyx both in blossom 

 and fruit, withering -persistent and enclosing the capsule; the tube within mostly ^vitll 10 narrow 

 appendages : style persistent : herbage pubescent. 



B. parviflora, Gray. Depressed, densely pubescent and viscid : leaves deeply pinnatifid : 

 flowers crowded in short spikes or racemes, on very short pedicels : corolla not longer than 

 the linear obscurely spatulate calyx-lobes : style hardly longer than the ovary: ovules 20 

 to 40: seeds 15 to 20. — Pacif. R. Rep. vi. 85, 1. 15. — Shores of Klamath Lake, borders 

 of California and Oregon, Newberry. Specimen poor. Except for the greater number of 

 ovules and the shorter style (which may be inconstant), this would be referred to the next. 



B. llitea, Gray. Diffusely branched, decumbent-spreading, more minutely pubescent, 

 ■ somewhat viscid but hardly or slightly glandular : leaves oblong or obovate, incisely few- 

 lobed or toothed or pinnatifid : flowers rather crowded in short racemes ; the lower pedi- 

 cels often longer than the calyx : corolla exceeding the spatulate-linear calyx-lobes : style
