characters relied upon to separate the new species are (a) the erect slender 
stems with the narrow leaves and secund thyrse, giving the plant the aspect 
of P. unilateralis Rydb.; (6) the pronounced puberulence of the plant below 
the inflorescence; (c) the short corolla, a third shorter than any of the other 
species of the P. glaber group; (d) the glabrous anthers; (¢) the habitat, the 
plant seemingly much at home on dry banks of ‘the sage brush deserts of 
western Idaho. All of these characters are directly opposed to the accepted 
ones of typical P. glaber Pursh. 
MacsrIpE 80, New Plymouth, Canyon Co., Idaho, May 21, roo, is the 
type. 
Pentstemon Woodsii, n. sp.—Moderately short pubescent 
throughout, and more or less glandular upward: stems wholly 
herbaceous, from the branches of a short woody subterranean 
caudex, erect, leafy, terminating in a small cyme of three or five 
flowers: leaves not at all coriaceous, oblong to oblong-lanceolate, 
acute, ascending, dentate or denticulate except the lower which 
are smaller than the others and entire, the larger 3 dm. or more in 
length and much longer than the internodes: sepals narrowly 
lanceolate, about 1omm. long: corolla purplish blue, gradually 
dilated upward, about 3 cm. long, its oval-oblong lobes less than 
5m. long, finely woolly in the throat on the lower lip: anthers 
dehiscent through the junction of the two cells but not explanate, 
finely matted-woolly; sterile filament not dilated at apex, the 
very tip bearing a few long woolly hairs: style slender, scarcely 
exserted but surpassing the included stamens. 
I would refer the present specimens to P. montanus Greene (of which I 
have seen no authentic specimens) were it not that GREENE says of that “leaves 
cinerously puberulent, corolla pink-purple, and sterile filament naked.” He 
would hardly have failed to mention the decidedly glandular pubescence of 
the inflorescence and the thin, not at all leathery, leaves. In TWEEDY ’S 
specimens, cited as the type, it is mentioned that the corollas ackent in drying, 
which is not the case at all in P. Woodsii. 
The fine specimens taken as the type were received from Mr. C. N. Woops, 
Supervisor of the Sawtooth Forest Reserve, no. 26 5, for whom it is a pleasure 
to name the species.
