510 HYDROPHYLLACE.E. Phacelia. 



oblong or linear lobes ; the lower petioled ; the upper sessile and less divided : 

 flowers cymose-clustered : corolla pale blue or nearly white : capsule about the 

 length of the calyx : ovules 40 or more : seeds minutely alveolate in vertical lines. 

 — Eutoca FranJclinii, E. Brown in Frankl. Jour. App. t. 27 ; Bot. Mag. t. 2985. 



Southwestern borders of Idaho, and therefore likely to occur in the northeastern borders of 

 California : extends northeastward to Lake Superior and Bear Lake. 



16. P. Menziesii, Ton-. Cinereous pubescent, and above mostly roughish-hir- 

 sute or even hispid, at length paniculately branched : leaves usually sessile, linear or 

 lanceolate and entire, or some of them cleft into 2 to 5 linear or lanceolate entire 

 divisions or lobes : inflorescence thyrsoid-paniculate, the spikes or spike-like racemes 

 at length elongated and strict : corolla bright violet, varying to white : capsule 

 shorter than the calyx : ovules 12 to 16 : seeds oblong, reticulate-pitted. — Hydro- 

 phyUum lineare, Pursh., Fl. i. 134. Eutoca Menziesii, B. Brown, 1. c. ; Hook. Bot. 

 Mag. t. 3762. E. multiflora, Dougl. ; Lindl. Bot. Beg. t. 1180. 



Common in open ground through the northern part of the Sierra Nevada, thence to Utah, Brit- 

 ish Columbia, &c. It is very : floriferous and handsome ; the corolla usually deep violet, half to 

 three fourths of an iueh in diameter. 



* * * Stamens shorter than the corolla (in No. 20, 21, sometimes equalling it) : 

 inflorescence spiciform or racemose. 



+- Leaves pinnatifid, elongated-oblong or spatulale ; the lobes short and obtuse : appen- 

 dages of the corolla narroio and nearly free from the filaments. 



++ Flowers {small) in at length elongated spnkes. 



1 7. P. brachyloba, Gray. A foot or two high, erect, roughish-pubescent, above 

 viscid-glandular: leaves short-petioled ; the 7 to 15 lobes entire or obtusely few- 

 toothed : spikes solitary or in pairs, slender : flowers very short-pedicelled : lobes of 

 the campanulate nearly white corolla about half the length of the tube: style 2-cleft 

 above the middle : capsule oblong-oval, very obtuse, thin, shorter than the calyx : 

 seeds 6 or fewer to each placenta. — Proc. Am. Acad. x. 324. Eutoca brachyloba, 

 Benth. 1. c. 



Near Monterey and Santa Barbara, in open ground, Douglas, Brewer, Torrey. 



++ ++ Flowers loosely racemose and long-pedicelled : stems low or diffuse, a span or 

 less high : leaves mainly at or near the base. 



18. P. Douglasii, Torr. Pubescent and hirsute with mostly spreading hairs : 

 leaves elongated-oblong or linear in outline, pinnatifid or pinnately parted into sev- 

 eral or numerous pairs of lobes ; the terminal lobe hardly larger than the others and 

 not parallel-veined : calyx-lobes spatulate : corolla open-campanulate, rather large : 

 ovules 12 to 14 on each dilated placenta: capsule ovate, mucronate. — Eutoca Doug- 

 lasii, Benth. 1. c. 



Open grounds, rather common from Monterey southward. In aspect considerably resembling 

 NemopMla insigiiis. Pedicels an inch or less in length, spreading. Corolla half an inch high, 

 and proportionally broad when expanded. 



19. P. Davidsonii, Gray, 1. c. Low and depressed : hoary with appressed hir- 

 sute hairs and a minute close pubescence : leaves deeply pinnatifid into one or two 

 pairs of triangular entire lateral lobes, and a much larger oblong or lanceolate termi- 

 nal one, the conspicuous veins of which are nearly parallel, or some upper leaves 

 entire : racemes few-flowered : calyx-lobes oblanceolate or linear : corolla small 

 (3 lines long), violet-colored : ovules 8 or 10 to each placenta. 



Kern Co., California, Prof. Davidson. In aspect resembling the species of the next section and 

 P. humilis, but with the long pedicels of the preceding ; the flowers much smaller. 



+- 4- Leaves entire, or the lower rarely 1 - 2-lobed, not cordate, the veins parallel or 

 converging as in P. circinata : no glandular pubescence : calyx hirsute or hispid
