DIADELPH1A DECANDR1A.

naceis, eglandulosis. I branaceous, without 
E. I glands. 
Stem apparently 1—2 feet high, thick, furrowed, and nearly glabrous. 
Leaves irregularly pinnate, leaflets small, hairy on the under surface, and 
under the microscope apparently covered with minute black glands. Sti- 
pules broad, ovate, membranaceous, without glands, sparingly fringed. 
Flowers on peduncles much longer than the leaves, and like the pre- 
ceding species, the spikes when young are closely imbricate. Brac- 
teas small, not above half the length of the calyx. Segments of the ca- 
lyx very long, acute and villous along the margins. Corolla violet colou- 
red, the carina rarely as long as the vexillum. The Legume I have not 
seen, but from the appearance of the germ i s mxmosp^ mons;. ll ujJ 
This plant I have thrown, though with some hesitation, into this section 
from the strong resemblance which it has in habit and in its mode of flow- 
ering, to the three preceeding species. It was collected some years ago, 
in Abbeville District, by Mr. Gourdine, and sent to me by Dr. Macbride.
