ains near Oakland, California ; March—April. The specimens from all these stations have the 
lobes of the flower furnished with a long caudate acumination, and the leaves are much more 
glabrous than in A. Canadense; but Bentham (Pl. Hartweg, p. 335) says that specimens from 
the mountains of Sacramento are more like the eastern A. Canadense, of which he thinks the 
Californian plant may be only a variety. 
CHENOPODIACEJE. 
TELOXYS CORNUTA (n. sp.): foliis repando-dentatis pinnatifidisque calycis laciniis acutis dorso 
. brevi-rostellatis, semine compresso margine obtusissimo. Rocky places, Hurrah creek, New 
Mexico. Near San Francisco mountain, Western New Mexico, Dr. Woodhouse, (omitted by 
accident in the botany of Sitgreaves' report); Wright's Coll., No. 1735. Gregg collected the 
plant near Saltillo, Mexico, (No. 390.) T. aristata differs in the entire leaves, inappendiculate 
glabrous calyx with obtuse segments, and acutely margined lenticular seeds. T. cornuta is 
commonly about a foot or 15 inches high, and is often very much branched. The leaves are deeply 
pinnatifid, with 2-3 distant lobes on each side. The calyx is beset with minute elevated glands, 
and on the upper part of the back of each segment is à short acute spine or tooth, so that in 
fruit the calyx appears somewhat stellate. The seed is exactly orbicular, thick, rounded on the 
margin, and closely covered with the utricle, which strongly adheres to its surface. Im T. 
aristata the utricle separates spontaneously from the seed. 
The genus Teloxys was established by Moquin on Chenopodium aristatum, and has hitherto 
consisted of that species only. Linnseus, in the second edition of the Species Plantarum, 
referred to C. aristatum, the Chenopodium Virginicum of his first edition, regarding it as a 
variety only. Dr. Gray, who saw the original specimens in the Linnean herbarium, informs 
me that the plant is nothing more than Sueda maritima; and yet it is difficult to understand 
how the description of Chenopodium Virginicum, in the Species Plantarum, (ed. 1,) could have 
been drawn from that plant. The first part of the character (‘‘foliis linearibus obtusis canalicu- 
latis””) agrees sufficiently well, but the latter portion (‘‘ peduncularibus axillaribus dichotomis””) 
is quite inapplicable. We greatly doubt whether a Teloxys has ever been found in any of the 
older United States. Moquin (in DC. Prodr.) states that he has seen Mexican specimens of T. 
aristata in the Vienna herbarium, but it is more than probable that the plant which he refers 
to is our T. cornuta. Without the leaves, (which fall away late in the season,) the two species 
are not distinguishable except by the use of a lens. 
CYcLOLOMA PLATYPHYLLUM, Mog. Chenop. p. 18, & DC. Prodr. 13, pars 2. p, 60. Salsola 
platyphylla, Micha. Sand-hills of the Canadian River ; September: flowers and fruit. 
CHENOPODIUM ALBUM, Linn. Alluvions of the Upper Canadian; September. C. subspicatum, 
Nutt. is hardly distinct. à 
CHENOPODIUM HYBRIDUM, Linn.; Moq. in DC. l. c. p. 68. With the last. 
Burrum CAPITATUM, Linn.; Moq. l. c. p. 83. Ravines, Sandia mountains, New Mexico ; 
October. It is difficult to believe that the last three species could have been introduced into a 
region so far removed from settlements of the whites.

OBIONE LENTIFORMIS, Torr. in Sitgreaves’ Report, p. 169, t. 14, 8 RHOMBIEOLIA : foliis rhom- 
boideo-ovatis undulatis. On Williams’ River of the Colorado of California; February, (with 
fruit of the preceding autumn.) This species forms impenetrable thickets twelve feet high ! 
The leaves are much larger than in the specimens collected in Captain Sitgreaves’ expedition, 
OBIONE HYMENELYTRA, Torr. in Emory's Rep. of Mex. Bound. Surv. (ined.) (Tab. XX.) Mills 
and gravelly places, on Williams’ River. This species was found by Dr. Parry and by Colonel 
Fremont on the Gila, Itis remarkable for its large broad membranaceous fruit-bracts, and 
roundish-deltoid coarsely and sharply toothed leaves.
