long; the petiole is 1 line long; the very deflected spine is 
extremely obtuse, almost truncated, 1 line long; each peduncle 
is I line long, thickened at its apex, and glabrous ; the two op- 
posite sepals are ovate, subacute, extremely concave, very fleshy, 
more concave at base, glabrous, ^ line long; the two petals are 
placed at the foot of the ovary, opposite the sepals, are orbi- 
cular, fleshy, one-fourth the length of the sepals ; the ovary is 
somewhat shorter than the sepals, glabrous, couico-oblong, with 
an almost obsolete 2-lobed stigma at its apex.

This plant is certainly distinct from the Cissampelos angusti- 
folia of Burchell, to which it was referred by Dr. Meyer. It has 
an erect stem, with virgate knotted branches and slender, rigid, 
striated, divaricated branchlets inch apart, almost spiny at the 
apex, and crowded with small leaves ; the leaves are 6-9 lines 
long, l|-2 lines broad, on a petiole about ^ line long; they are 
covered on both sides with a whitish bloom, but are quite gla- 
brous. The specimen in M. de Boissier’s herbarium is taken 
from a much branched and knotty plant, with quite the habit 
of a Lycium ; its very woody primary and secondary branchlets 
stand at an angle of from 45° to 60°, the latter being 1^ inch long ; 
the leaves are fasciculated, as in Drege’s specimen. The pedun- 
cles are 1 or 2 lines long, each bearing at its summit three or 
four approximated 1 -flowered pedicels ^ line long, bracteolated 
at base, so that the flowers appear in a capitate head ; the flower 
expanded is J line in diameter. 
27. Dissopetalum. 
This genus is proposed for a species belonging to Mauritius 
and Madagascar, long since known, but imperfectly examined —
