from the base of each cell. 'The style is erect, simple, some- 
what shorter than the stamens. The stigma is clavate, green, 
with 2 compressed rugose lips. The fruit is a berry with 
very little pulp, inclosing 2 hard obovate nuts, flat within, 
rounded outside, each having at the base 2 distinct aper- 
tures, which on the inner side extend some way upwards, 
outside they are separated by a short spine; in this aperture 
may be seen the strophiole of the seed, by which it receives 
its nourishment from the fleshy support of the nut: the 
testa is of a dark green hue, oblong, compressed, smooth, 
tapering below, exhibiting on the inner flattened side, the 
before-mentioned protuberant prolongation of the testa: the 
endopleura is a very thin membrane covering a hard fleshy 
albumen which encloses the embryo: this is amphitropous 
and filiform ; the radicle which points to the base is terete, 
a little swollen below ; the cotyledons are incumbent, sharply 
curved at their origin, becoming somewhat straight towards 
the extremity which closely approaches the end of the 
radicle.

tab. 1985 :—parce spinosa, frondosa: foliis ovatis, apice 
acutis, basi in petiolum longum cuneatis : floribus paucis, 
corolla alba, fauci viridi-venosa, limbo subviolacea.—Rio 
Grande, Brazilie meridionalis. (Sellow). 
This appears to be a more bushy, and far less spiny 
species than any of the others, the foliage seems dense, the 
leaves more elliptic, and the purplish flowers few in each 
axil, while in the Peruvian species, with which it has been 
confounded, the flowers are white, and crowded in almost 
terminal corymbs. 
Dr. Walpers (Repert. Bot. Syst. 3. 113) adds 2 other 
species, but there appears no reason for placing the first 
(G. disticha. Meyen.) in this genus, since the fruit is un- 
known, and its characters agree quite as well with Lycium. — 
The other (G. Meyeniana Nees. Atropa spinosa, Meyen.) 
is the plant I have described under the name of Lycioplesium 
Meyenianum (ante p. 332. Iam not acquainted with the
