Hab. Realejo. — Stems stout and woody, almost terete, the branches obtusely 4-sided, clothed, as are the 
leaves, calyx and ovary, with erect, close-pressed, pale, rusty coloured shining setm, giving a silky appearance 
to the eye. Leaves 2 inches or 2| inches long, on rather short petioles, oblong-lanceolate, entire, acute, 
marked with from 3-5 strong, parallel nerves. Flowers corymbose on small terminal branches, which collec- 
tively form a corymbose panicle. Flowers crowded, and rather small. Calyx 5-cleft ; the tube ovate, marked 
with ten slightly elevated lines, and, as well as the lanceolato-subulate erect lobes, clothed with appressed, 
rigid hairs; the lobes are eventually deciduous. Petals 5, oblongo-obovate, ciliated. Stamens 10, 4 large 
and 4 small ; but the anthers all uniform, linear, opening by a single conspicuous pore at the extremity, and 
furnished at the base with a projecting horizontal tubercle. Ovary ovate, the lower half adherent with the 
base of the calyx, the upper half free, and covered wilh erect, close-pressed bristles ; style clavate, glabrous. 
The fruit is a capsule included within the truncated calyx.

Hab. Acapulco. — From the former Mexican collection we attempted to draw up a character of this plant 
with the aid of only very imperfect specimens. Those from Dr Sinclair have both flower and fruit. The 
male flowers are green and about as large as those of our Bryonia diocia. Filaments 3. Anthers combined 
and flexuose. The berries are rather larger than those of the common Bryony, filled with white mealy pulp, 
and flat seeds.

Hab. Acapulco. — The fruit here is more perfect than in our former specimens, and is ovoid.
