170 HYDROPHYLLACEyE. Phacelia. 



++ I>eaves deeply once or twice pinnatifid: short fruiting pedicels erect: corolla half inch long: 

 pubescence minute, more or less viscid. 

 P. Fremontii, Torr. 1. c. A span to a foot high, much branched from the base : 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 f unnelform, 

 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. Iving, 253; Gray, I.e. — 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 ovaloblong: seeds about 16, shorter, minutely corrugated. — Watson, 

 Bot. King, 255 ; Gray, 1. c. ^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. gymnoclada, 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 length 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 

 rather 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. — Reese River 

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



6. EMMENANTHE, Benth. (From l^niva, I abide, and avdog., flower, 

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

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

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

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



§ 1. MiLTi'xziA, Gray. Diffuse or depressed, and with the general characters 

 of Phacelia § 3ficrogenetes, except the persistent corolla : flowers small : calyx- 

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

 as minutely reticulated. — Miltilzia, A.DC. Prodr. ix. 296. 



* Corolla bright yellow, merely 5-lobed, exceeding or at least equalling the calj^x both in blossom 

 and fruit, withering persistent and enclosing the capsule; the tube within mostly with 10 narrow 

 appendages : style persistent : herbage pubescent. 



E. 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 mamath Lake, borders 

 of California and Oregon, Newhen-y. Specimen poor. Except for the greater number of 

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



E. 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
