long, hairy, though attenuated toward the base; seeds oval, indistinctly 
tuberculated; stamens shorter than the petals ; stigma discoid —Camp Bowie, 
Ariz. (460). Var. LAVANDUL&FOLIA, 8. Watson. (Q2nothera lavandulefolia, 
T. & G.)—Much smaller; leaves linear, hairy, obtuse, 4-12” long; calyx- 
tube much more slender and the “calyx-segments less attenuated above”.— 
Collected by Dr. Loew in Arizona. Widely different in appearance. Var. 
Fendleri, S. Watson, may be usually known at a glance by being glabrous, 
having oblong lanceolate leaves and larger flowers, with a broad throat. It 
comes from the same region. 
(EnoruerA Greco, Gray (Pl. Fendleri, p. 46).—‘‘Searcely more 
than a variety of the last. More shrubby and diffuse, low, viscidly pubes- 
cent or more or less hirsute; leaves ovate to oblong, 1-3’ long, acute, 
mostly: sessile; flowers mostly terminal, calyx-tube slender, 8-15”; petals 
acutish, 3-6’’ long, capsule 4’ long.”"—(Warson, Proc. Am. Acad. viii, p.

CENOTHERA ALyssorDESs, Hook. & Arn.—Utah. 
CEnotTHERA Boortutt, Dougl.—Nevada. 
CENOTHERA SCAPOIDEA, Nutt.—Utah. Also, var. purpurascens. ‘‘ Flowers 
larger, pinkish-white or purplish, rarely yellow, tube 2-3” long ; petals 3—4” 
long.”—( Watson.) Nevada.* : 
Gaura coccinea, Nutt. —Perennial, from a woody root, canescent ; 
leaves lanceolate or linear, entire or irregularly sinuate dentate, 4-14’ long; 
bracts persistent, about as long as the mature fruit; reflexed calyx-lobes a 
little longer than the tube; style pilose at base ; stigmatic indusium annular, 
margin entire or nearly so; fruit canescent, contracted in its lower third 
into a-thick terete neck—Nevada, Arizona, and Colorado (160, 161). 
Smooth form (159), Colorado.

In the absence of proper fruit, on which I must depend to aid in assigning 
this specimen to a place, I felt inclined to regard it as merely a form of G. 
coccinea, which the structure of the flower much resembles. Dr. Gray (who 
*It is but just that I should state (what is, however, obvious) that in casting the species of
