and somewhat scabrid: the pollen is compressed, 3-gonous, 
with a small rounded lobe at each angle, from which 3 con- 
vergent lines meet in the centre: the ovarium is supported 
upon a short, distinct, but somewhat slender column, which 
in many species is somewhat glandular, and this is sur- 
rounded by the persistent base of the corolla, which inva- 
riably breaks off as it falls, by a horizontal line, leaving a 
cylindrical cup: the ovarium is divided into 2 cells by a dis- 
sepiment, which presents in its centre a thickened placenta- 
tion, and upon this are suspended, by a short ligular strap, 
upon their ventral faces, a small number of ovaria in each cell : 
the style is filamentous, glabrous, and of the length of the 
tube of the corolla: the stigma is capitate, being formed of 
2 lamellar lobes, whose inner surfaces are covered with a 
thick green glutinous exudation: the berry is oval, scarcely 
fleshy, and each cell presents 4 ripened seeds: these are 
somewhat obovate, rounded on the outside, and angular on 
the inner face, a little above the centre of which is the hilum, 
from which the seed is suspended by its short ligular strap: 
the testa is of a dark green colour, of very soft texture when 
fully ripe: the albumen is soft and fleshy, in the centre of 
which is seen the erect embryo, which is white, and as in 
most other Cestrinee, lays longitudinally across the hilum, 
the cotyledons are small, flat, and rounded, two-thirds of the 
length and twice the breadth of the terete radicle, which 
points towards the bottom of the seed.*

foliis elongato-lanceolatis, acuminatis; margine subundu-

The leaves are 4 in. long, 8 lines broad, ona caniculate 
petiole, 3 lines in length: they have no pseudo-stipules. The 
racemes are 9 lines long, which I found only in seed: the
