This plant was also collected by me, at a spot a few miles distant from where the pre- 
ceding species was gathered ; it was found by Dr. Gillies at the same place, and by others on 
the opposite side of the Andes. It has so much the habit of Ephedra ochreata, a native 
of the same region, that, except for its inflorescence, it might be mistaken for a kindred 
species of that genus. It darkens more than the preceding species (becomes altogether 
black) in drying. The axils are from 23 to 33 in. apart, and are articulated by a transverse 
line formed by the union of the opposite petioles of the decayed leaves; each branchlet 
has a short articulation above its base, 1 or 2 lines long, as in Ephedra. The leaves are 
seen only on the young branches, as they soon wither; they are about 14 line long, 
$ line broad, thick, black, subdenticulated, with a slender very short recurved petiole. 
The inflorescence is like that of the preceding species, 14-2 in. long, but the flowers are 
somewhat larger; the subovate bract is squamiform, scarcely 1 line long; the calyx is 3 
lines long; the tube of the corolla is 4 lines long, curving sigmoidly outwards and more 
swollen above the middle than in Sir W. Hooker's drawing, the lobes are 1 line long ; 
inside upon the anterior side the tube is retrorsely pilose; the fifth sterile filament is 
very distinct, but from its tenuity might be overlooked; the style is dilated and curved 
at the apex and does not extend beyond the mouth: the construetion of the ovary is 
precisely like that of the typical species. The fruit does not appear to be known; 
Sehauer, who did not see it, assumed it to be a 4-coccous capsule—which must be a 
mistake, judging by the structure of the ovary.
