face towards the ovarium. Pollen valves two, opening 
laterally from top to bottom; pollen of a light lilac color, 
globular, each grain with a netted external membrane, 
said by Dr. Hugo Mohl to secrete an oily substance 
which determines its color. I have observed many with 
à small projection, like a pedicel, probably the situation 
of the tube passing down the pistil. Stigmas three, sessile, 
curved back and opening like the valve of an anther, each 
being formed by the union of the upper parts of the two 
adjacent projecting angles of the ovarium, which is six- 
angled and three-celled ; placente central, dissepiments 
in the interior of each alternate depression between the 
angles, such depression being that opposite to the verti- 
cillus of sepals; the placent: meet in the centre but are 
not attached to each other. When the fruit is ripe, it is 
a red, soft, pulpy berry, in which it is difficult to distin- 
guish the various parts or their attachments. 
The seeds are monocotyledonous and fixed by a spe- 
cies of funiculus, sufficiently visible in the early stages 
of its growth, to the two sides of each placenta ; at ma- 
turity the chalaza is very distinct, the vessels of the 
raphe proceed from thence, on the outside of the seed, 
about midway towards the foramen, where they branch 
out as in fig. 9, and are, as well as about one fourth of 
the seed, enveloped in a pulpy mass, adhering with some 
tenacity to the testa, probably a secretion or emanation 
from these vessels, as it is found also on abortive ovula, 
where there is nothing but the testa, although not so 
largely developed as in the perfect seed. "The raphe 
can only be seen when the seed is moist ; a few minutes 
exposure is sufficient to dry it up and render it invisible. 
The outer and inner testa are membranous, the first 
a darker brown than the other, reticulated with veins,
