P. canosobarbatum, (Kellogg) or Grey-Bearded Pentstemon. — 

 Stern glabrous, glaucous fruticose(?) Leaves lanceolate cuneate at 

 base, sharply remote serrate, short cuspidate, somewhat recurve 

 spreading, petioles short, (radical leaves unknown). Peduncles one 

 to three-flowered, scarlet or red. 



Calyx segments equal, ovate-lanceolate, very slenderly acute. 



Corolla colored, tube short, (as in P. brevifiorus) one-fourth of an 

 inch in length, about one-third longer than the calycine segments ; 

 resupinate(?) Upper lip three-lobed, vertical or slightly reflexed ; 

 lesser middle lobe lanceolate acute, lateral ones obliquely broader or 

 rhombic lobes, bearded externally ; lower lip slightly two-notched, 

 horizontally somewhat ascending carinate, densely bearded below, 

 mostly at the extremity, with white or long transparent frosted hairs. 



Sterile filament short, naked, somewhat erect, villous at the base. 

 Style longer than the stamens. Stigma simple, slightly capitate. 

 Stamens exsert, anthers glabrous. Filaments geniculate at the base, 

 flattened below the prominent angle, margins of the expanded base 

 villous, glabrous above from the angle, ascending in a corresponding 

 curve with the lengthened lower lip. 



P. rostriflorum, (Kellogg). — Stem glabrous, somewhat ancipital by 

 the decurrent mid-ribs of the leaves. 



Leaves linear-lanceolate, entire, sessile mid-rib sharply prominent, 

 decurrrent erect or sub-spreading. Peduncles two-flowered, (rarely 

 more than one fully developed) glandular, second ascending, as long. 

 or longer than the leaves. Bracts minute. Calyx lanceolate attenu- 

 ate-acuminate, lower segments scarcely longest, acuminate, glandularly 

 villous, villi very minute. 



Flowers tubular, (nerved) creamy yellow, one inch in length, tube 

 three-fourths, refracted, not ventricose ; minutely glandularly villous 

 externally, mostly at the lips ; upper lip longest, staight, somewhat 

 vaulted, two notched ; lower lip two-lobed, lobes linear acute. 



Stamens nearly equal, two longest of the length of the flower, 

 inserted at the lowermost margin of the tube, declined ascending above, 

 thickened and compressed at the base ; shorter pair, with the fifth 

 inserted into the tube one-eighth of an inch above the base ; fifth fila- 

 ment shorter than the stamens included in the upper lip, glabrous. 



Style about the length of the stamens.
