equaling the tube: corolla broadly funnelform, larger, diameter at 
the top more than 2 cm.; the plaits purple, alternating with green 
bands extending downward from the lobes, the sinuses short. 
This would be a good species if all st leading to the above characters 
were not present in a collection of nis. Collected at Mountain City, 
Elko Co., Nevada, August 9, 1912, no. eee 
_?Nemophila explicata, n. sp.—Branching from the base; the 
branches sometimes sparingly branched, 7-15 cm. long, spreading 
or weakly erect, glabrate, the scattering hairs short and refracted: 
leaves obovate or orbicular in outline, cuneately tapering into a 
margined petiole one-fourth to one-half as long as the blade, 
crenately 3—-5-lobed, 10-20 mm. long, sparsely strigulose with more 
or less appressed hairs: pedicels 7-14 mm. long, at length more or 
less reflexed or even refracted: flowers small, not white; calyx 
appressed strigulose, in fruit 2 mm. or scarcely more long; its tube 
short; its lobes ovate, sparsely short ciliate on the margins, its ap- 
pendages small, oblong, as long as the tube: corolla small, barely 
exceeding the calyx, tubular-campanulate, its oval lobesal most as 
long as the tube, the plicae or appendages wholly wanting: style 
short, divided at apex only: capsule 3-4 mm. long, more or less 
appressed cinereous-strigulose: seeds 4, large, 3 mm. long, irregular 
quadrants, slightly roughened, pale yellow with numerous small 
brownish dots or obscurely pitted; the membranous cellular car- 
uncle caplike. 
Secured at Jarbidge, in the canyon of the East Bruneau River, among shale- 
lava, growing with N. breviflora Gray. Only one other of the described species 
seems to be devoid of appendages in the corolla tube. No. 2229, July 7 7, 1912, 
is the type 
Phacelia foliosepala, n. sp.—Slender annual, 7-12 cm. high, 
hirsute-pubescent and glandular, trichotomously — branched 
(candelabra-like) twice or thrice, the branches usually simple, 
floriferous to near their bases: leaves few, scattering, I-1.5 cm. 
long, oblanceolate, obtuse, tapering below to a short margined 
petiole: inflorescence racemose, rather open in fruit (flowers 
unknown): pedicels about 2 mm. long: calyx lobes foliar, unequal, 
resembling the leaves, 10-15 mm. long, more than twice as long as
