466 HYDROPH'YLLACEAE nemophh-a 



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 8-34: 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 in 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. parviflora Dougl. Hook. Fl. ii, 79. Rough-pubescent with short 

 retrorse hairs : stems slender, 4-16 inches long branching from the base, 

 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 and 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. 



N. densa. N. parviflora 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 apiculate 

 lobes : calyx 1% lines long, with subulate lobes and linear appendages : 

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

 campanulate, decidedly shorter than the calyx; the lobes considerably 

 shorter than the tube; appendages in the throat cuneate, the broad free 

 summit fimbriate-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 Phacelieae 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 

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

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

 meeting of the linear or lanceolate placentae in the axis: these sep-
