long: calyx hirsute, deeply parted, with lanceolate lobes and linear appen- 

 dages : corolla an inch or less in diameter, rotate, the ample obcordate lobes 

 white or light blue speckled with dark blue: scales at the base of the 

 short tube narrow, wholly adherent their free edge densely hirsute-ciliate : 

 ovules 8-24: seeds 5-15, globular, with a very prominent papillaeform ca- 

 runcle. Common in open places, Willamette "Valley Oregon to California. 



N. pedunculata Dougl. Hook. Fl. ii, 79. Minutely ^hispid: stems 

 slender, 2-6 inches high, paniculately branched: leaves bipinnatifid or the 

 upper ones pinnate only, with rounded lobes : calyx 5-parted, with oblong 

 acute lobes, the appendages iu the sinuses very small or obsolete : corolla 

 white, 4-5 lines broad, the obovate emarginate lobes longer than the tube 

 and surpassing the calyx; appendages in the throat broad and glabrous: 

 stamens inserted on the base of the corolla and not longer than its tube : 

 ovules: a pair to each placenta: seeds globose; the caruncle at length eva- 

 nescent. In damp places, southern Oregon to California. 



N. paryiflora Dougl. Hook. Fl. ii, 79. Rough -pubescent with short 

 retrorse hairs: stems slender, 4-16 inches long branching from the ba?e, 

 prostrate or ascending: leaves broadly ovate in outline 6-10 lines long by 

 4-8 lines broad, pinnately 5-lobed, with ovate acute and mucronate lobes, 

 the lower sometimes coarsely 2-3-toothed ; petiole shorter than the blade: 

 peduncles slender, an inch or less long in fruit: calyx 2 lines long or less, 

 deeply 5-lobed with lanceolate lobes inconspicuous linear appendages: 

 corolla white, campanulate,. but little longer than the calyx, the rounded 

 obovate lobes longer than the tube, the appendages in the throat linear 

 and glabrous, or almost obsolete : stamens inserted on the base an 1 not 

 exceeding the tube of the corolla: anthers short, cordate, very obtuse: 

 ovary 4-ovuled, very hispid : capsule much longer than the calyx, 1-4- 

 seeded. Common in forests ; western Oregon and Washington. 



H. deiisa. N. paryiflora Gray in part. Sparingly pilose : stem some- 

 what succulent, decumbent and spreading from the base, forming dense 

 round mats 2-3 inches in diameter: leaves oblong in outline, 6-7 lines 

 long by 2-4 lines broad, pinnately 7-parted, with obovate, barely apicu- 

 ]ate lobes: calyx 1% lines long, with subulate lobes and linear appenda- 

 ges: corolla blue, campanulate or more open, twice as long as the calyx ; 

 the broad lobes longer than the tube: the ovary 4-ovuled, pubescent: cap- 

 sule longer than the calyx, 1-4-seeded. Under small trees in open places, 

 Washington to California. 



N. breviflora Gray Proc. Am. Acad. xi, 315. Stem erect, 4-10 inches 

 high, weak, branching from the base: leaves sometimes all alternate, pin- 

 nately 5-parted, the divisions approximate, oblong-lanceolate, acute, entire, 

 3-9 lines long: peduncles seldom exceeding the petioles: appendages of the 

 calyx nearly half the length of the proper lobes, both ciliate, with long hir- 

 sute bristles : corolla whitish or tinged with violet, broadly short-campan- 

 ulate, decidedly shorter than the calyx; the lobes considerably shorter than 

 the tube; appendages in the throat cuneate, the broad free summit fim- 

 briate-incised : style minutely 2-cleft at the apex : seed usually solitary, 

 almost filling the cell, globular, nearly smooth and even ; the caruncle 

 evanescent. In the Blue Mountains of Oregon. 



Tribe 2 Phaceliex B. & H. Gen. ii, 826. Calyx naked at the 

 sinuses, deeply 5-parted. Corolla imbricated in the bud. Style, 

 from 2-parted to entire: the branches at the apex or the stigmas ob- 

 scurely if at all thickened. Ovary mostly hispid or pubescent, at 

 least at the apex, either strictly 1-celled or 2- celled by the meeting 

 of the linear or lanceolate placentae in the axis: these separating in 

 the loculicidal dehiscence and borne on the middle of the semiseptif-
