recurvis, in apice petioli glandulis duabus stipitatis ercctis; spiels in apice ramulornm tcrmiiialibus

Nomcn vcrnacul. " Olivo." In tlic soutlicrn parts of the Pro^^nce of Panama. 
A tree 30 feet high, with smooth grey branches. The leaves strongly resemble those of some "Willows ; 
they are of an obloug, somewhat lanceolate form, finely serrulated at the margin, a little narrowed at 
both ends, hooked at the obtuse apex in an incurved manner, and 3-5 inches long by G-12 lines broad. 
Petioles 4-8 lines long, furnished at the enda with two opposite stalked glands. Spilccn generally 4 inches 
long, terminal, bearing flowers of both sexes ; upper part of the spike densely covered with male flowers of 
a yellowish colour, arranged in clusters of seven to twelve small flowers, each containing^two stamens, 
surrounded by a membranaceous, two-cleft, globular calyx ; each cluster supported by an ovate fringed 
scale, several hair-like appendices, and below these with two brown, sessile, panel-shaped glands. The under 
part 'of the spike bears from six to eight distant, solitary, female flowers, each with a two-leaved membrana- 
ceous calyx, and a globular, dark green, trilocular germen, cro^vned with a sessile, whitish, obtusely and 
shortly thrce-lobed stigma. The female flowers, like the male clusters, are supported by an ovate scale, 
several hair-like appendices, and two small, oblong, whitish glands.

Although the habit of the specimen before me seems to be very diS'erent from that of Omphalea 
diandra, Linn., still I think it better to consider it as a variety, than as a new species ; for on comparing 
several specimens of O. diandm from different localities, I find a great variation in the form of the leaves, 
especially at their bases, notwithstanding they diff-er in the proportion between the length and breadth of 
the leaves, and the margin is always entire : the leaves of the var. Panamcmis arc 4-5 inches long and only 
half as broad, while those of the true O. diandra are 5-6 inches long and 3M inches broad.

A shrub from 10 to 12 feet high. Branches erect ; petioles half an inch long ; leaves from 4 to G inches 
Ion- and H to 2^ inches broad; spikes remote, 1 inch long, and towards the apex as thick as the quill of 
a r^ven -This species is alUed to Acalypha leptostaclya, H. B. K., from Turbaco, A. befuhrdcs, Herb. Ruiz., 
from Pern A. Billhergiana, Kl. (Tragia) sp. nov., Billherg, n. 226), from Portobelo, A. .amy<Ufoha, Poepp.

meria spicigera, Sprengl. Hcrl. Balb. n. 2308), from Santamarta ; from aU of which however it differs m 
many essential points.
