tion of California. The following all bear single and short-peduncled flowers in the axils of 

 ordinary cauline leaves, but the uppermost leaves are sometimes a little reduced, giving a ten- 

 dency to racemose inflorescence. 



* Leaves all broad and somewhat cordate or truncate at base: stems very leafy : propa- 

 gating by filiform subterranean shoots: tubers none or hardly any. 



1. S. galericulata, Linn. Minutely pubescent or partly glabrous : stem a foot 

 or two high, simple or at length loosely branched : leaves thin, ovate-lanceolate or 

 the upper lanceolate, an inch or two long, acute, piunately veiny, all but the upper- 

 most serrate : corolla pubescent, light blue (about two thirds or three fourths of an 

 inch long), with slender tube and enlarging throat ; the lower lip nearly erect and 

 larger than the upper. 



Wet grounds in the Sierra Nevada (Plumas Co., Lemmon) : extending north to British Columbia 

 and east to the Atlantic. The only species common to America and the Old World. 



2. S. Bolanderi, Gray. Minutely soft-pubescent : stem a foot high, simple or 

 branched from the base, equally very leafy to the summit : leaves thinnish, oval, 

 obtuse, with subcordate base, closely sessile, an inch long or less, entire, or the 

 lower sparingly somewhat crenately toothed, a pair of veins from the base on each 

 side : corolla whitish or cream-colored, two thirds of an inch long, much enlarged 

 above from a short tube ; the lower lip ample. Proc. Am. Acad. vii. 387. 



Wooded portion of the Sierra Nevada : at Clark's, Mariposa Co., Bolandcr. Also Indian Valley, 

 Plumas Co., Lemmon. Leaves 18 to 22 pairs, mostly longer than the internodes. Neither tubers 

 nor filiform subterranean shoots have been seen. 



* * Leaves, at least the upper ones, narrowed or merely obtuse at base, 



-t- From oblong to linear, entire or nearly so : stems erect : filiform subterranean 

 shoots abundant, but slightly if at all tuberiferous. 



3. S. angustifolia, Pursh. Minutely cinereous-pubescent or almost glabrous, 

 a span to a foot high : stems simple or branching from below : leaves from linear to 

 narrowly oblong (about an inch long), all but the lower acute at the sessile base or 

 tapering into a slight petiole ; the radical leaves often roundish or even cordate and 

 sometimes toothed : pedicels as long as the calyx : corolla blue or violet, an inch 

 long, with slender tube and moderately enlarged throat ; lower lobe villous inside. 



Var. canescens, Gray : a form with soft-hoary pubescence, and the tube of the 

 corolla often with recurving base, and above this erect or thrown somewhat back- 

 ward. S. siphocampyloides, Vatke in Bot. Zeit. xxx. 717. 



Sierra Nevada and foot-hills, from Placer Co. northward, extending to British Columbia. The 

 var. canescens along the mountains from Monterey Co. to Lake Co. 



4. S. antirrhinoides, Benth. A span to a foot and a half high, resembles the 

 preceding, but with broader and oblong leaves abruptly short-petioled ; the upper 

 sometimes lanceolate ; the lower often serrate : corolla shorter and broader through- 

 out, from half to three fourths of an inch long, apparently paler. Gray, Proc. 

 Am. Acad. viii. 396. S. resinosa, Watson, Bot. King Exp. in part. 



Var. Californica, Gray, 1. c. Stems more rigid : corolla apparently yellowish, 

 more ventricose, its tube more enlarging immediately above the calyx. S. angusti- 

 folia, Benth. PI. Hartw. 331 (No. 1918), is a narrow-leaved form of this. 



Along streams, Alameda to Mendocino Co. Also in Oregon and the mountains of Nevada. 



-t- *- Leaves ovate, petioled: stems low or diffuse: propagating by filiform subterranean 

 shoots terminated by moniliform tubers. 



5. S. tuberosa, Benth. Soft-villous or pubescent, an inch or two high, or at 

 length with diffuse or trailing stems a foot long, slender : leaves thin, from cordate- 

 ovate to obovate or the upper cuneate-oblong, slender-petioled, coarsely more or less 

 toothed : corolla pubescent, blue or violet, over half an inch long, and with rather 

 slender tube.
