—— tifications which every where cover it.— Perianth none.— Corol none. 
— Filaments; 1 conclude there are about eight to each germ, two 
on each face; but the want of both perianth and corol, renders it 
difficult to assign the exact number of stamens to each floret, they 
are very short, and seem inserted on the base of the germ. Anthers 
sub-sagittate, four-lobed. Germs numerous, parallelopiped, trun- 
cate, vertically attached to, and completely covering every part of 
the common cylindric receptacle, one-celled, with one seed attach- 
ed in an oblique manner to the bottom of the cell. The substance 
of the germs is replete with rigid, sharp, vertical bristles, which are 
readily detached, and stick in the skin, causing pain and itching. The 
virtue of the drug may reside in these, as it does in the short stiff. 
hairs of the legumes of Carpopogon pruriens. Style none, Stigma, 
a channel filled with gelatinous matter, running from the cell of the 
germ to the centre of the truncate apex, where it ends in a small 
slit, embraced by two darker-coloured, somewhat callous lips.—Pe- 
ricarps (capsule circumscissg), as numerous as the germs, and 
of the same form, only larger; a few only are fertile, of a soft fleshy 
texture, one-celled, one-valved ; when the fruit is ripe they detach: 
themselves from the receptacle, and drop off, leaving the seed be~ 
hind still attached to it.— Seed single, ovate-cordate, somewhat two- 
lobed, covered at the base with a thin, red, succulent aril. Integu- 
ments: two, exclusive of the aril, exterior pale yellow, polished, thin, 
hard, and elastic ; inner membranaceous. Perisperm none. Em- 
bryo uncinate, white, very succulent. Radicle inferior, thickened,. 
and in other respects exactly as in Geertner’s figures of Potamageton 
natans, vol. it. p: 93. t. 84. 
Obs. 'The Sa dèscribed by Sir William Jeius by the name of 
Guj-peepul, (see Asiatic Researches, vol. iv. p. 303.) is my Tetran-- 
ihera apetala. He, however observes, that it was from a native gar- 
dener he obtained the Sanscrit name of bis plant, but as he mentions 
that Valli means a creeper, he suspects in some degree, the accuracy 
of his information:
