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

 three fourths of an inch in diameter. 



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

 inflorescence spiciform or racemose. 



-f- Leaves 2>innatifid, elongated-ohlonc; or spatulafe ; the lobes short and obtuse : appen- 

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



+■5- Fhmers (^smcdl) in at length elongated sjnkes. 



17. 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, Bonglas, Brcxccr, Torrcy. 



-i-i- -!-+ Fl Givers loosely racemose and long-pedicelled : stems loiv or diffuse, a sp)an 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, Bentli. 1. c. 



Oprii i:;ninii(ls, rather common from Monterey southward. In aspect considerablj' resembling 

 Ni-ntiijiliiiii iiisiipiis. Pedicels an inch or less in length, spreading. Corolla half an inch high, 

 and prripditicuially broad when expanded. 



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

 sute Iiairs 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 liowers much smaller. 



+■ -f- Leaves entire, or the lorver rarely 1 — 2-lobed, not cordate, the veins parallel or 

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