246 NELSON: NEW PLANTS FROM WYOMING 
broadly to narrowly so, 7-15 mm. long, glabrous above, nearly so 
below, crowded and more bract-like upward: flowers small, cym- 
ulose in the axils, short-pedicelled and bracteolate: calyx about 
5 mm. long, its lower teeth surpassing the upper, somewhat hispid- 
pubescent -on the tube and teeth: corolla inconspicuous, barely 
surpassing the longer calyx-teeth, the upper lip 2-lobed; stam- 
inodia wanting. . 
Not closely allied to any of the northern species. The type 
number, collected by the writer, on Pole Creek, June 30, 1895, 
was distributed as 7. Reverchoni, to which it may be most nearly 
allied. 
“Castilleja pilifera sp. nov. 
Perennial, more or less finely pilose throughout ; stems several 
from the crown of a caudex, slender and erect from a somewhat 
decumbent base, 15—25 cm. high: leaves numerous, flaccid, nearly 
linear, entire or with one or more linear divergent lobes, 3-6. 
cm. long: calyx a little shorter than the bracts, equally cleft 
above and below to the middle; the lobes linear and rarely more 
than bidentate at apex: corolla about 2 cm. long (shorter than 
the calyx), tubular; the lip as long as the galea and about one 
fourth as long as the tube, its linear teeth as long as the obscurely 
saccate base. 
It is strongly to be suspected that most if not all the plants of 
the Rocky Mountains that have heretofore been called C. pilosa 
(Orthocarpus pilosus) are not that species at all. That species was 
founded on very limited material, but the original description by 
Watson, in Bot. King’s Rep., 231, calls attention to the calyx, 
‘cleft nearly to the base anteriorly, 4-lobed to the middle and 
shorter than the corolla.” The description in Flora of California 
may cover this species alone, but that of Gray, Syn. Fl., un- 
doubtedly is more inclusive though too brief to indicate that fact 
clearly. C. pilosa probably belongs in the Sierra Nevada and 
northwestward. 
The type of C. pilifera is no. 5878, A. & E. Nelson, Soda 
Butte, Yellowstone Park, July 15, 1899. It was distributed as 
C. pilosa. 
“ Symphoricarpos Tetonensis sp. nov. 
Wholly glabrous; branches dark brown, with smooth bark 
(not shreddy) ; the young twigs light brown; leaves green, some- 
what lighter beneath and subglaucous, narrowly elliptic and taper-
