tion of California. — The following all hear singlo and aliort-ppdunrlnd flowers in the oJcils of 

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

 dency to racemose inflorescence. 



* Leaves all broad and xnmewhat cordate or truncate at base: stents 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 iit lengtli loosely branched : leaves thin, ovate-lanceolate or 

 the upper lancoolnte, nil inch or two long, acute, pinnately veiny, all but the upj)er- 

 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., Lemmun): 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 tliinnish, oval, 

 obtuse, with subcordate ba.se, closely sessile, an inch long or less, entire, or the 

 lower sparingly .somewhat crenately toothed, a j)air 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., Bolamlcr. Also Indian Valley, 

 Plumas Co., Lrmmon. Leaves 18 to 22 pairs, mostly longer than the intemodca. Neither tubers 

 nor fdiform subterranean shoots have been seen. 



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



-»- From oblong to linear, entire or nearly so : sterns erect : filiform subterranean 

 shoots abundant, hut slightly if at all tuberifa'ous. 



3. S. angUStifolla, Pursh. ^linutely cinercoiis-pubescent or almost glabrous, 

 a span to a foot high : stems simi)lo 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, Avith slender tube and moderately enlarged throat ; lower lobe villous in.side. 



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 Lot. Zeit. xxx. 7 1 7. 



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 

 ])recctling, but witli broader and oblong leaves abruj)tly short-pctioled ; the upper 

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

 out, from half to three fourths of an incli 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. Ilartw. 331 (No. iOlS), is a narrow-leaved form of this. 



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



+- -^Leaves ovate, petioled : stems loir or difuse: propagating by filiform subterranean 



shoots terminated by monitiform tuber's. 



5. 8. tuberosa, Tlonth. Soft-villous or pubescent, an inch or two high, or at 

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

 ovate to obovate or the upj)er cuneate-oblong, slender-petioled, coarsely more or less 

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

 slender tube.
