404 Netson: NEw PLANTS FROM WYOMING 
mostly obtuse blades (5—10 cm. long) ; the lower stem-leaves simi- 
lar, tapering into short petioles, the upper ovate-lanceolate, sub- 
acute, sessile: flower-clusters terminal and axillary, at length open- 
paniculate among the large floral leaves: calyx cleft nearly to the 
base, the lobes triangular-lanceolate, sparingly ciliate, more than 
half as long as the corolla-tube: corolla tube rather broad, about 
5 mm. long, not noticeably hairy within near the base ; limb a little 
shorter than the tube ; the lobes suborbicular, abruptly dilated from 
the rounded sinus: stamens inserted a little below the conspicuous 
crown of crests in the throat; filaments as long as the anthers, 
dilated, as broad or broader than the anthers which do not equal 
the lobes of the corolla. 
Probably somewhat related to J. papil/osa Greene and in some 
points to M. foliosa A. Nelson, but not very closely to either. 
It seems to be confined to the Leucite formations of south-central 
Wyoming, occurring among the rocks on the buttes of the Leucite 
Hills. Collections as follows: Sweetwater county, June 9, 1900, 
no. 7071 (type) ; Steamboat Mt., same county and date, no. 70725 
N. Vermillion Creek, July 24, 1897, no. 3593.

CASTILLEJA ANGUSTIFOLIA dubia 
: The woody caudex short, giving rise to few or several, slender, 
simple, ascending or erect stems, 2-3 dm. high : pubescence sparse, 
cinereous, consisting of fine puberulence and some white, soft hairs + 
the body or axis of the leaf linear, 3-5 cm. long, 3-5 mm. broad, 
usually with 1 or 2 pairs of widely divergent linear lobes which are 
one third to one half as long as the leaf: bracts shorter, the blade 
and lobes relatively broader and tending to become scarious, de- 
cidedly yellowish or at the summit bright yellow: calyx about 2 
cm. long, equally cleft to nearly one third its length: corolla 
scarcely longer than the calyx; the galea and tube subequal ; lip 
almost wanting, not noticeably saccate, truncate and short-toothed. 
C. angustifolia Don, is really a species of the far Northwest 
Its history and characters are well set forth by Mr. M. L. Fernald 
in Erythea, 6: 46. In the specimens cited, two from Wyoming 
are included which possibly are similar to those now before m& 
While it seems possible that the variety here proposed might prop 
erly be constituted a species, yet, as Mr. Fernald’s description 1 
drawn, I find no good differences except the yellow color, scantier 
pubescence (especially in the inflorescence), shorter corolla and 
sparser leafiness and the longer more open spike in the variety-
