long, 5 lines broad across the three lobes, 2 lines broad imme- 
diately below them, thence tapering to the base; they are 
scabrid beneath, with large conical white crystalline tubercles, 
that bear on their apex a short rigid hair; the solitary flowers 
are axillary, on a pedicel 3 lines long; the-tube of the calyx 
(3 lines long) has from twelve to fifteen erect terete teeth, 
3-1 line long, connected at their base by a short plicated 
membrane : the five appendices form a simple whorl round the 
base of the corolla; one or two of them are spathulate upon 
an elongated slender claw 2-3 lines long and ? line broad at 
the apex ; the others are sessile, setiform, 1 line long, all seri- 
ceously pilose outside, smooth inside; the tube of the corolla 
is 3} lines long, the lobes of the border are 12 line long, 1 line 
broad ; the filaments, fixed just within the mouth, are 2 lines 
long ; the lower part of the style is 3 lines long, its branches 
2 lines long; the drupe is ovoid, with a thin coriaceous cover- 
ing having a saline taste, is 6 lines long, 5 lines broad, half- 
enclosed within the cupular cup of the persistent calyx ; the two 
plano-convex nucules are 4 lines long, 3 lines broad, hard and 
osseous, each with two distinct cells with foraminal aper- 
tures as above described, each cell containing a suspended seed 
covered by its colourless integuments ; the embryo, enveloped 
in an extremely thin albumen, has two (sometimes three) 
equal cotyledons, which are three times the length of the 
conical superior radicle*.
