New Plants. 
By Edward Lee Greene. 
(Enothera HiLGARDi. — Annual, canescently puberulent, 3-6 
inches high, divaricately much branched ; leaves linear, spatulate, 
entire, 1-2 inches long, including the petiole, the lamina deflexed ; 
branches corymbose in flower, densely spicate in fruit, the spikes 
leafy; petals 2^ lines long, obovate, entire ; capsule -J inch long, 
straight, sharply angled, attenuate from base to apex ; seeds strongly 
clavate, pale, smooth and shining. 
Collected on moist alkaline soil of the Klickitat Swale, Washing- 
ton Territory, in July, 1882, by Prof. E. W. Hilgard. 
It is nearly related to CE. andina, Nutt., but is a larger plant, 
with a depressed habit of growth, much larger flowers, sharply angu- 
lar capsules, and clavate seeds. The seeds of CE. andina are linear- 
oblong, darker colored, and not so smooth. 
CoRETHROGYNE DETONSA. — Suffrutesccnt (?), branches very leafy 
up to the base of the loose panicle ; leaves sub-coriaceous, oblong- 
oblanceolate, 2-4 inches long, their whole margin coarsely serrate- 
toothed, densely white tomentose beneath, less so above, the upper- 
most linear-oblong and finely serrate ; involucres large, campanulate, 
of numerous, rigid, densely woolly scales, in many ranks ; receptacle 
without chaff ; style-tips without bristles, but coarsely short pubes- 
cent under a lens. 
The single rigid, leafy branch, apparently that of a more or less 
shrubby plant, is in the herbarium of the California Academy, with- 
out a note to indicate whence or through whom it was obtamed. 
Though unmistakably a Corethrogyne, it lacks the main technical char- 
acter of the genus, /. e., the bristly style-tips ; or at least the long 
bristly hairs of the other species are, in this, shorn down to a mere 
pubescence, which is not apparent to the unaided eye. The specimen 
has the appearance of being very old, and may have come from some 
island of the Californian coast long ago. 
Encelia stenophylla. — Shrubby, glabrous and apparently some- 
what glutinous ; leaves two or three inches long, narrowly linear, en- 
tire, crowded on the branches ; heads small, rather numerous, in a 
rather close and mostly long-peduncled corymb ; involucre less than 
half the length of the disk, its closely imbricated scales lanceolate, 
with sparingly hispid-ciliate margins ; akenes cuneate-obovate, densely 
villous throughout, each margin bearing a stout awn. _ ^ 
Collected many years since on the Cedros (wrongly written 'Cer- 
ros") Islands, by Dr. Veatch, whose copious specimens have re- 
mained in the herbarium of the California Academy of Science, hith- 
erto unnoticed. . ^ 
Hemizonia (Hartmannia) Kelloggii.— Diffusely paniculate, 
1-3 feet high, stout and somewhat hispid ; cauline leaves pmnatifid, 
1-3 inches long ; those of the branchlets smaller and entire ; heads 
numerous and scattered, of 5-6 ray- and only 3-4 disk-flowers; both 
stipe and beak of ray-akenes very prominent and strongly bent ; pap- 
Pus of disk-akenes mostly united at base, or even to the middle, form- 
ing a tube.
