quite the appearance of a Colletia ; the spinules generally are 
from 6 to 9 lines long, the internodes being somewhat shorter ; 
the leaves, including the petiole, are only 1 line in length, and 
half a line in breadth ; they are deflected, naviculate, with a 
recurved apex. In Sir Wm. Hooker^s figure, the peduncle is 
1 line long, the tube of the calyx is 2 lines long, the same in 
diameter, and the border-segments half that length ; the disk, 
adnate to the bottom of the calyx, has a narrow, free, crenulated 
margin. The peduncle in the fruit is much thickened, striated, 
and elongated to 2 lines ; the capsule is globular, somewhat 
depressed, 2 lines in diameter, half imbedded in the persistent 
cup of the calyx, which is of a fuscous reddish hue, is 10-ribbed, 
and glabrous ; the free rim of the adnate intermediate disk runs 
parallel above the margin of the cupuliform base of the calyx ; 
the thick and somewhat coriaceous epicarp of the capsule splits 
along its grooves in the form of three persistent valves, oiving 
to the pressure of the three cocci, which thus escape from their 
enclosure with an elastic spring ; these cocci are thin and horny, 
splitting along the line of the central axis, and partly along that 
of the dorsal face, exactly after the manner of the Euphorbiacece^.

This plant is very like a Lycium in habit ; its branches are 
straighter than in the preceding species, and are quite glabrous ; 
its opposite spines are spreading, or | inch long and ^ an inch 
apart ; the lower ones are bare, but towards the extremities of 
* This plant is shown in Plate 38 a of this work.
