This plant, in its general habit and floral characters, quite 
agrees with all the foregoing species ; but it difiFers from them 
in the more membranaceous epicarp of its capsule, which splits 
near the margin of the cupuliform disk, and remains attached 
to the resilient cocci, as in Colletia and Ochetophila. It grows 
in sandy places, forming a mean-looking bush, 2 or 3 feet high; 
its branches are virgated and spinose ; its spreading spines 
measure ^ inch to inch ; the leaves are 4 to 6 lines long, 
line broad, on a petiole ^ line in length ; the peduncle is 
slender, and 2 lines long; the calyx, including its segments, 
measures only 1 line in length and in diameter. 
4. Ochetophila. 
This genus, proposed, but not published, by Poppig, was first 
described by Endlicher, in his Gen. Plant. (No. 5733), founded 
upon the Sageretia trinervis of Gillies, and comprising two other 
plants from Chile, which were designated by name only, and are 
still undescribed. It is distinguished from Discaria by many 
slight characters, among which is the form of its peculiar sti- 
pules. In the latter genus, the petiole springs from the sinus 
between the teeth of each retinaculoid stipule, the margins of 
which are connected with those of the opposite stipule by a 
transverse line. In Ochetophila, the petioles of the opposite 
leaves spring directly from the branch ; they widen at their base, 
and embrace the stem so far that their edges meet together in 
the middle of the node, giving it an articulation of a character 
different from that in Discaria : in eaeh axil above the base of the 
petiole is seen a broad, concave, somewhat erect, dark red, scale- 
like stipule, which is bifid at its apex, with ciliated margins. 
The structure of its flower much resembles that of Discaria, and 
the shape and formation of its fruit are similar ; its petals, how- 
ever, are proportionally larger, more cucullate, and they often 
completely hide the stamens ; the free portion of the filaments 
is eomparatively longer ; the disk is like that of Discaria. The
