 X. 324, & Bot. Calif. 1. c. Eutoca brachyloba, Benth. 1. c. — California, near ilonterey and 

 Santa Barbara [Douylas, Brewer, Torrey), to San Diego Co. {Cleveland) and the iXohave 

 region. Palmer. 



-H- ++ Flowers loosely racemose. long-pedicelled : corolla fblue or purple or varying to white) open- 

 carapanulate, 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, pinnatifld 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 dQated. placenta 12 to 14: capsule ovate, mucronate : seeds roundish-oval, 

 scrobiculate. — Bot. ilex. Bound. 143 ; (Jray, 1. c. Eutoca Doiiglasii, Benth. 1. c. — California, 

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

 somewhat of Xemophila insignis. Pedicels half an inch to an inch long, spreading. CoroUa 

 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 pinnatifld 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-asceuding or 

 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— -i^ -i^ Leaves entire (or the lower rarely 1-2-Iobed or toothed), petioled, not fleshy nor cordate, 

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

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

 at base and united with theba^e of the (usually pubescent or sparsely bearded) filaments: cap-ule 

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

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

 4-1- Corolla narrow, somewhat funneltorm, little longer than the cal^rx. apparently pale or white, 

 much exceeding the stamens. 

 P. circinatif onnis, Gray, I. 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. circinaia. 

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