Var. WiSLizENi, Gray, Proc. Am. Acad. vi. 59 (P. coccineus, Engelm. in Mem. Wisliz. 

 107), known only from Chihuahua, Mexico, is between P. barbatus and P. imberbis, having 

 nearly the corolla of the latter, with the early divaricate anthers of the former. 

 ^_ ^_ Corolla obscurely bilabiate and the lobes hardly spreading : peduncles and pedicels short. 

 P. Batoni, Gray. A foot or two high, hardly glaucescent : leaves from lanceolate to 

 ovate ; the upper partly clasping : thyrsus virgate and strict, simple ; the peduncles very 

 short, 1-3-flowered, and pedicels seldom much longer than the ovate-lanceolate sepals : 

 corolla an inch long, bright carmine-red, tubular, hardly enlarged at the naked throat ; its 

 broadly oval lobes (2 hnes long) all nearly alike except that the two of the upper lip 

 are united higher; anther-cells usually (but not always) early divergent or divaricate, 

 dehiscent for only three-fourths their length : sterile filament sometimes minutely bearded 

 at the apex.— Proc. Am. Acad. viii. 395, & Bot. Calif, i. 560, but flowers in Wallace's 

 collection, mistakenly referred to it, are of P. Clevelandi. P. centranthifolius, Watson,

 Nevada and Arizona. Intermediate in aspect between P. barbatus and P. centranilufolius. 

 4(; # # # # (Speciosi.) Anthers with the diverging or divaricate and distinct cells dehiscent 

 from base nearly or quite to, but not confluently throui^h, the apex, not peltately explanate after 

 dehiscence, either glabrous, hirsute, or rarely long-pilose : herbs with simple stems and closely 

 sessile mostly very glabrous (rarely puberulent) entire cauline leaves : inflorescence never glan- 

 dular-pubescent or viscid : flowers showy : corolla blue or violet, ventricose-ampliate above 5 the 

 lobes of the moderately or slightly bilabiate limb roundish and equally spreading. 



H— Corolla two-thirds to three-fourths inch long, funnelform, little ventricose. 

 P. Fremonti, Torr. & Gray. A span or more high, minutely and densely pruinose- 

 pubescent : cauline leaves lanceolate or the lowest (like the radical) spatulate : thyrsus 

 spiciform, virgate, rather densely flowered ; peduncles and pedicels very short : sepals 

 oblong-ovate, acute, with irregular scarious margins : corolla very obscurely bilabiate ; the 

 lobes 2 lines long: anthers hirsute: sterile filament with dilated bearded apex. — Proc. 

 Am. Acad. vi. 60. — Utah, " on the Uinta plains," Fremont. 



Var. subglaber. A span to a foot high, merely puberulent below, glabrous above : 

 upper leaves oblong-lanceolate: sepals conspicuously acuminate. — Idaho (in mountains 

 near Fort Hall, Burke), &c. 



•t— ■*— Corolla an inch to an inch and a half in length, ventricose-ampliate above. 

 P. strictus, Benth. Glabrous, or minutely pruinose, more or less glaucous : stem slen- 

 der, virgate, 6 to 20 inches high : radical leaves from oval to spatulate ; cauline narrowly 

 lanceolate or linear ; floral reduced to small subulate bracts of the elongated narrow and 

 loose thyrsus : peduncles and pedicels commonly slender : sepals ovate or oval, obtuse, not 

 over 2 lines long, barely half the length of the narrow proper tube of the violet-purple or 

 blue (about inch long) corolla; the throat of which is strongly ampliate: anthers either 

 thickly or sparsely comose with very long flexuous hairs : sterile filament naked or with 

 some similar slender hairs. — DC. Prodr. x. 324. P. comnrrhenus, Gray, Proc. Am. Acad, 

 xii. 81. — Eocky Mountains of W. Wyoming to those of S. W. Utah. The original speci- 

 men {Fremont} is strict, with the inflorescence imperfectly developed, and no good corolla 

 extant, the cauline leaves 2 or 3 inches long and 2 lines broad. The long and soft, but 

 rather coarse hairs of the anther are not rarely a line and a half in length. 

 P. glaber, Pursh. Glaucous or glaucescent and very glabrous : stems ascending or 

 erect, a foot or two high : leaves mostly oblong-lanceolate or the upper ovate-lanceolate : 

 thyrsus elongated and many-flowered : peduncles and pedicels short, commonly very short : 

 sepals from orbicular-ovate and merely acute to ovate-lanceolate or strongly acuminate 

 from a broadish base: corolla (1 to H inches long) bright blue to violet-purple: anthers 

 (and also the apex of sterile filament) from glabrous to sparsely hirsute; the cells dehis- 

 cent to or very near their apex. — Fl. ii. 728, & Bot. Mag. t. 1672, &c., under the form P.
