372 Mr. J. Miers on the Tribe Colletiese. 



which closely resembles that of the following species, which I 

 received from Tweedie. In its intricately spinose habit, it has 

 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, owing 

 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 Euphorbiacea*.

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, f or J inch long and | an inch
