Phacelia. HYDROPHYLLACE^. 167 



oblong, incisely pinnatifid ; the short lobes very obtuse or retuse, sometimes 1-2-lobed : 

 spikes mostly cymose or geminate, elongated in fruit, dense ; the pedicels very much 

 shorter than the calyx : corolla pale purple or white, funnelform ; the rounded and some- 

 what erose lobes not half the length of the tube ; its appendages narrow-oblong, free from 

 the stamens : ovules 8 to 12 on each dilated placenta : style 2-cleft at the tip : capsule 

 oblong, very obtuse or retuse, membranaceous, about the length of the narrow spatulate 

 calyx-lobes: seeds (about 20) oval, reticulated. Bot. Mex. Bound. 144. New Mexico, 

 near the Santa Rita copper mines, Wriijht, Bit/flow (and south into Chihuahua, Bigelow). 

 Habit of P. congesta, &c. Corolla nearly 3 lines long, narrow. Capsule 3 lines long. 



j -t Leaves simply pinnatifid ; the lobes short and obtuse. 



H- Flowers crowded in at length elongated spikes : corolla small, white or nearly so. 

 P. bracliyloba, Gray. A foot or two high, erect, roughish-pubescent, viscid-glandular 

 above : leaves elongated-oblong or spatulate, short-petioled ; the 7 to 15 lobes entire or 

 obtusely few-toothed : spikes solitary or geminate, at length much elongated and slender: 

 pedicels very short : corolla campanulate ; the lobes about half the length of the tube ; its 

 long and narrow appendages nearly free from the stamens : ovules about 6 on each pla- 

 centa : style 2-cleft above the middle : capsule oblong-oval, very obtuse, membranaceous, 

 shorter than the narrow spatulate calyx-lobes : seeds oval, reticulated. Proc. Am. Acad. 

 x. 324, & Bot. Calif. 1. c. Eutoca brachyloba, Benth. I.e. California, near Monterey and 

 Santa Barbara (Douglas, Brewer, Torre y), to San Diego Co. (Cleveland) and the Mohave 

 region, Palmer. 



H- - Flowers looselv racemose, long-pedicelled : corolla (blue or purple or varying to white) open- 

 campanulate, twice the length of the calyx ; the appendages elongated, nearly free from the base 

 of the usually sparsely bearded filament: low and diffuse, a span or less high, with the leaves 

 mostly at or near the base. 



P. Douglasii, Torr. Diffuse, pubescent and hirsute with mostly spreading hairs: leaves 

 elongated-oblong or linear in outline, pinnatifid or pinnately parted into several or numer- 

 ous pairs of lobes ; the terminal lobe not larger nor parallel-veined : racemes at length 

 elongated : pedicels filiform, mostly longer than the flower : calyx-lobes spatulate : append- 

 ages to the tube of the ample corolla semi-oblanceolate : style 2-cleft above the middle : 

 ovules to each dilated placenta 12 to 14 : capsule ovate, mucronate : seeds roundish-oval, 

 scrobiculate. Bot. Mex. Bound. 143 ; Gray, 1. c. Eutoca Douglasii, Benth. 1. c. California, 

 apparently rather common in the western part of the State south of Monterey. Habit 

 somewhat of Nemophila insignis. Pedicels half an inch to an inch long, spreading. Corolla 

 generally half an inch high, and proportionally broad when expanded. 



P. Davidsonii, Gray. Resembles the preceding, but more hairy and hoary, the foliage 

 with strigose, the racemes and calyx with villous-hirsute and spreading pubescence : leaves 

 deeply pinnatifid into 2 to 4 triangular entire lateral lobes and a much larger oblong ter- 

 minal one, the evident veins of which are nearly parallel with the midrib (in the manner 

 of P. humilis and of the succeeding) ; some of the upper leaves occasionally entire : pedi- 

 cels seldom longer than the fructiferous calyx, in age inclined to be recurved-ascending dr 

 sigmoid : calyx-lobes narrowly spatulate : appendages to the tube of the corolla semi-oval : 

 ovules to each placenta 8 or 10. Proc. Am. Acad. x. 324, & Bot. Calif, i. 510, a depau- 

 perate and small-flowered form. California, in Kern Co., Prof. Davidson, the small form 

 above mentioned. San Bernardino Co., a larger form, with flowers fully the size of P. 

 Douglasii, and limb or lobes of the corolla bright purple, Parry and Lemmon. 

 -I H H Leaves entire (or the lower rarely 1-2-lobed or toothed), petioled, not fleshy nor cordate, 

 the veins somewhat parallel or converging: pubescence not glandular: flowers spieate-racemose : 

 calyx hirsute or hispid with long spreading hairs: appendages of the tube of the corolla broader 

 at base and united with the base of the (usually pubescent or sparsely bearded) filaments: capsule 

 ovate, acute or mucronate, 6-16-seeded, much shorter than the linear or linear-spatulate enlarging 

 calvx-lobes: seed with favose-pitted or scrobiculate testa. 

 H- Corolla narrow, somewhat, funnelform, little longer than the calyx, apparently pale or white, 



much exceeding the stamens. 



P. circinatif ormis, Gray, 1. c. Erect, a span or so high, hispid and puberulent : leaves 

 ovate and oblong-lanceolate, parallel-veined, somewhat strigose-hispid : racemes or spikes 

 dense : style 2-cleft above the middle : ovules 4 (or rarely more) to each placenta. Eutoca 

 phacelioides, Benth. 1. c. California, Douglas (from whose collection only is the species yet 

 known), probably from the vicinity of Monterey. Aspect of a small form of P. circinata, 

 Corolla 2 to 3 lines long. Fruiting calyx 5 lines long.
