208 UNITED STATES AND MEKICAN BOUNDARY. 
Tepopote and Cañatilla, and use a decoction of it as а remedy for gonorrhea. It is a shrub 
about two feet high with numerous branches, the sheaths of which are short, 2-3-cleft, the divisions 
lanceolate or subulate, spreading or recurved, at length deciduous. Sterile aments opposite or 
aggregated at the nodes. Anthers mostly 4. Fertile opposite, 1-2-seeded. The sheaths of | 
the ament mostly 4, deeply 2-cleft and somewhat fleshy. Seeds smooth, when in pairs flattened | 
on the face, when solitary they are larger and obtusely triangular, nearly twice аз long as the 1 
inner scales. Tube of the micropyle very obliquely truncated. | 
There are numerous specimens in the Mexican Boundary Collections, of an Ephedra, found at 
Frontera and near Doña Ana, which may be a distinct species, but I suspect it is an abnormal state - 
of E. antisiphilitica. It is a shrub of 3 to 5 feet in height. The fertile aments are ovate-oblong, 
«J > and instead of four decussating pairs of connate thickish, or at length succulent scales, there 
1777777" ave trom 16 to 20 very broad, entire, thin and membranaceous scales, which are distinct, contracted 
into а short stipe at the base, and irregularly inserted on the axis. "They are at first loosely 
imbricated, but at length more or less spreading. The seed (immature) is ovate with a tapering 
point, and except the long obliquely truncated micropyle, is wholly covered with the scales. 
23 Another Ephedra occurs at Fronteras, and it has also been found at Ojo de Vaca in Chihuahua, 
Ё oy PY Mr. Thurber. It resembles the one just noticed, but the scales, though equally numerous 
ry = and arranged in the same manner, are smaller and less membranaceous. They are also minutely 
erose-serrulate. The seeds, however, are roughened with minute points which are sometimes 
disposed in short transverse rows, so that, unless pretty highly magnified, they look like 
wrinkles of the testa. The micropyle is conspicuously exserted beyond the scales. There are 
usually but two seeds in each fertile ament, but not unfrequently three. The arrangement of 
the scales of the fertile aments in these two Ephedre is so much at variance with the character 
of the genus, that it seems most probable they are abnormal forms,

Mexico, Chihuahua, and Sonora, (No. 1889, Wright ; No. 830, Fendler; New Mexico.) The 
cones and nuts greatly resemble those of "the next species. "The leaves are almost always in 
pairs, very rarely in threes. Gordon, in the work just quoted, refers this species to P. mono- 
phylla, Torr. & Frém.,the name of which, he says, was changed to P. Fremontiana by Pro- 
— fessor Endlicher, (Syn. Conif. p. 188,) because that botanist having ‘ ‘afterwards examined more 
perfect specimens, found that the leaves were in twos and threes, and that the solitary leaves 
arose from Dr. Torrey’s specimens being gathered from stunted plants.’ Now, we find that 
Endlicher in his Synop. Conif. has no remarks of this kind. His entire description is taken 
from mine in Frémont's 2d Report; but he regards what І call a single leaf, as consisting of — . 
two united leaves. Col. Frémont found extensive forests of the tree in his first expedition, as + | 
well as in his journey of 1853-'54. Dr. Bigelow also found it in Whipple's expedition on the a 
mountains of California, but in consequence of an oversight it was not included in the Botanical || : 
Report of that expedition. The characters appearing to be so constant, I retain the species, and 
wait for additional observations on the plant in its native places of growth. It would be de- 
sirable, also, to test the constancy of the species by cultivation. Gordon’s ж (1. с.) герге-
