it is far removed geographically and has the broad leaves and the 
aspect of P. perpulcher. Since this plant differs in the same manner 
from its allies as the species previously discussed, it seems advisable 
to consider it as a species, although further knowledge may show 
these characters to be of no consequence taxonomically. But in 
accord with our present interpretation var. pandus must become

Pentstemon Albrightii, A. Nels., n. sp.—Growing in small dense 
tufts, or often as single individuals, the crown or crowns furnished 
with coarse fibrous roots: leaves mostly basal, tufted on the crowns, 
glabrous, erect, 3-8 cm. long (including the petiole), spatulately 
oblanceolate, tapering gradually into the petiole, subacute or 
rounded at apex: stems one or more from each crown, scapose, the 
leaves if any remote and bractlike, sparsely floriferous for half their 
length or more, 1-2 dm. high, glabrous except in the inflorescence 
which becomes glandular pubescent upward: flowers in a more or 
less unilateral open raceme: calyx small, dark (greenish-purple), 
the lobes slightly unequal, as long or longer than the campanulate 
tube: corolla glabrous inside and out, a pale lavender, 9-13 mm. 
long, the tube slightly or not at all dilated, the limb short and 
abruptly spreading: sterile filament glabrous, slender, and much 
Shorter than the others: anther cells confluent but not explanate: 
Style as long as the corolla tube, stoutish, with small stigma. 
This species is singular in its few-flowered, open, almost simple, secund 
racemose cyme. A few of its characters suggest the genus Chionophila, 
particularly its rosulate leaves, scapose stems, and greatly reduced sterile 
filament. The inflorescence is such, however, that the aspect of the plant as a 
whole is that of Pentstemon. The floral, fruit, and seed characters are also 
those of Pentstemon. It lacks those determinative characters of Chionophila, 
namely, the Nha calyx, the marcescent corolla, and the large strongly 
angulate see 
It was a collected by J. F. Macsripe, in 1910, in the Trinity Lake 
region of Idaho. Then it was secured by Dr. C. C. ALBRIGHT, of Anaconda, 
Montana, in 1914, but both of these collections were inadequate and poor. It 
was tentatively named as given from ALBRIGHT’S material, but until now it has 
not seemed wise to publish. Fortunately, Macsrme and Payson found it 
again in Idaho and secured an abundance of excellent material. Their no. 
3570, from the Josephine Lakes, Custer County, is the type. They also
