274 SCBOPHULARIACE.E. (FIGWORT FAMILY.) 



1. Anther-cells soon divaricate or divergent, united and often confluent at the 

 apex, dehiscent for their whole length or nearly. 



* Anthers densely comose with very long wool, peltately explanate in age : low and 



suffruticose, with coriaceous leaves. 



1. P. Menziesii, Hook. From a few inches to a foot high : leaves com- 

 monly ovate, obovate, or oblong, to 1 inch long, rigidly serrulate or some 

 entire, glabrous or when young pubescent : inflorescence mostly glandular or 

 viscid-pubescent, racemose : pedicels almost all 1 -flowered: corolla violet-blue 

 to pink-purple, an inch or more long, tubular-funnelform and moderately bila- 

 biate : sterile filament short and slender, hairy at apex or nearly naked. On 

 rocks and in the mountains, from Wyoming to California and northward. 



* # Anthers glabrous (rarely villous) ; the cells dehiscent from the base towards 



but not to the apex : corolla tubular, red: sterile filament mostly glabrous : herbs 

 glabrous and usually glaucescent : leaves all entire ; the cauline sessile or partly 

 clasping: thyrsus elongated, loosely-flowered. 



2. P. barbatUS, Nutt. Usually tall, 2 to 6 feet high : leaves lanceolate 

 or the upper linear-lanceolate ; the lowest oblong or ovate : sepals ovate : 

 corolla strongly bilabiate, an inch long, from light pink-red to carmine ; base of 

 the lower lip or throat usually bearded with long and loose or sparse yellowish 

 hairs. Mountains of Colorado and New Mexico. 



Var. Torreyi, Gray. A tall and usually deep scarlet-red-flowered form, 

 with few or no hairs in the throat. -Bot. Mex. Bound. 114. From Colorado 

 and New Mexico to W. Texas. 



Var. trichander, Gray, is like a low form of var. Torreyi, except that the 

 anthers are beset with long woolly hairs. Proc. Am. Acad. xi. 94. S. W. 

 Colorado, Brandegee. 



3. p. Eatoni, Gray. A foot or two high : leaves from lanceolate to 

 ovate ; the upper partly clasping : peduncles very short, 1 to 3-flowered : corolla 

 obscurely bilabiate, an inch long, bright carmine-red ; its lobes all nearly alike. 

 Proc. Am. Acad. viii. 395. From the Wahsatch Mountains, Utah, to Ne- 

 vada and Arizona. 



* # * Anthers with the diverging or divaricate and distinct cells dehiscent 



from base nearly or quite to the apex, but not confluent, not peltately explanate 

 after dehiscence, either glabrous, hirsute, or pilose : herbs with simple stems and 

 closely sessile glabrous entire cauline leaves : inflorescence never glandular- 

 pubescent or viscid: flowers showy: corolla blue or violet. 



4. P. Fremonti, Torr. & Gray. A span or more high, minutely and 

 densely pruinose-pubescent : cauline leaves lanceolate or the lowest and radi- 

 cal spatulate : thyrsus spiciform, virgate, rather densely flowered : sepals oblong- 

 ovate, acute, with irregular scarious margins : corolla very obscurely bilabiate, 

 f unnelform, f to inch long, ivith throat but little dilated : anthers hirsute : 

 sterile filament with dilated bearded apex. Proc. Am. Acad. vi. 60. "On 

 the Uinta plains," Utah, Fremont. 



Var. subglaber, Gray. Merely puberulent below, glabrous above: upper 

 leaves oblong-lanceolate : sepals conspictiously acuminate. Synopt. Fl. ii. 262. 

 In the mountains near Fort Hall, Idaho, etc.
