branchlets having an apiculate termination; the branches are 
quite glabrous; the spines, | to I 5 inch long, are always articu- 
lated in the middle, and there floriferous ; the fertile hranchlets 
that spring from below them bear an abundance of flowers and 
leaves, with the axils approximated, so that the inflorescence 
appears somewhat spicated ; these branchlets, though sometimes 
much longer, seldom exceed half an inch in length, bearing 
in each node two opposite sets of three fasciculated flowers and 
two opposite leaves ; the leaves are from 6 to 9 lines long, 
3 lines broad, on a petiole one line in length ; those of the main 
branches are 1 inch long, and half an inch broad, the margins 
generally revolute, with crenated, almost obsolete teeth, and 
yellowish. The peduncles are nearly 2 lines long; the broad 
and urceolate tube of the calyx is 1 line long, its segments and 
erect stamens | line in length ; the small hypogynous disk, 
adnate to it, is slightly concave, green, smooth, fleshy, with a 
raised undulating margin, and is half as broad again as the very 
pilose ovary which it supports. The 3-coccous fruit is about 
2 lines in diameter, and pilose ; when the cocci spring out of 
their bed, which they do with a noise and much elastic force, 
their persistent cup is seen to be formed of three distinct and 
stout membranes, — the base of the calyx, the disk, and the ad- 
hering portion of the epicarp. The seeds are oval, dark brown, 
hard and polished, like those of Colletia. The stipules are very 
conspicuous, especially in the young floriferous branchlets ; here 
they form in each axil a minute hollow navicular cup, with two 
erect, obtuse, ciliated, red, membranaceous lobes, connected with 
those of the opposite stipule by a short membranaceous vaginant 
sheath ; the petiole springs out of the sinus between the lobes, 
and the three peduncles grow out of the hollow of the cup*. 
Dombey^s plant, labelled as from Peru, is beyond doubt from 
Chile. Germaines specimens were distributed under the name 
of Trevoa S-nervis.
