228 PITTONIA. 
somewhat recently have any plants been collected from any- 
where near the probably original station which answer to 
Nuttall’s description of S. cordatus. ‘These are from Wyo- 
niing and eastern Utah, and are so very unlike the plants 
described above that it has seemed needful to indicate the 
two new species, in comparison with either of which the 
Wyoming plant, still very rare in collections, has the thin- 
nish leaf-texture characteristic of all the more typical Strep- 
tanthi, as also a short and dense raceme or spike of pale 
flowers, the very short stamens which Nuttall attributes to 
his type, sepals not bristly at tip, and the pods relatively 
narrow and deflexed or recurved. 
The specimen in my herbarium, which I confidently take 
for the only real S. cordatus which I possess, is from near 
Evanston, Wyoming. Two others quite like it are in the 
U.S. herbarium from eastern Utah. And it must have been 
in about this same region, a little further north perhaps, but 
in Wyoming, that Nuttall obtained this plant, and several 
other of his new species in other genera, which have not yet 
been found elsewhere, and which the later generation of 
botanical travelers have been slow to rediscover. 
HIERACIUM BARBIGERUM. Stems slender, barely 4 foot 
high, apparently from deep-seated roots or rootstocks, leafy 
only toward the base, the subcorymbose inflorescence ter- 
minating a scapiform peduncle: leaves somewhat crowded, 
not rosulate, but erect or ascending, lanceolate, short-petio- 
late, acute, entire, 3 or 4 inches long: petioles and leaf- 
margins notably hirsute with long spreading hairs which 
extend more sparsely to both faces of the leaf, and still more 
sparsely to even the stem and peduncles, the lower faces of 
the leaves also minutely tomentulose with branched hairs: 
heads only 3 to 5, long-peduncled, 4 or 5 lines high; invo- 
lucre strongly hirsute in the manner of the foliage, with also 
a few dark setulose hairs and some of the minute tomentu- 
lose hairs: flowers yellow : achenes not known.
