their edges. All or part of them are sometimes wanting. The an- 
droceum is formed of an indefinite number of hypogynous stamens, 
with free filaments and two-celled anthers, extrorse, or partly introrse, 
dehiscing by two longitudinal clefts. The gynæceum is composed 
of a free ovary, and surmounted by a simple, entire style with stig- 
matiferous scarcely dilated apex. The ovary contains three oppositi- 
petalous cells, or from four to six cells, in the internal angle of which 
a large descending bilobed placenta is seen loaded with anatropous 
ovules. The fruit is a polyspermous berry, accompanied at the base 
by the persistent calyx ; and the seeds lodged in a fleshy pulp, con- 
tain under their resistant coats a fleshy albumen surrounding a 
straight embryo, with thick cotyledons a little larger than the radicle. 
Prockia also consists of shrubs of tropical America, of which five or 
six species' have been described. The leaves are alternate, often 
dentate like a saw, multinerved at the base, accompanied by two 
lateral stipules. The flowers are terminal, disposed in simple racemes, 
or in racemose cymes. 
After Prockia we range Hasseltia, which has very similar flowers 
in four or five parts, and an ovary with two or three cells, each 
having in its internal angle a placenta covered outwardly with nu- 
merous ovules; Plagiopteron having biovulate ovary cells and a 
fruit in the shape of a reversed triangular pyramid, surmounted by 
three horizontal rings; and So/msia, apetalous diclinous flowers, 
with an indefinite number of stamens, sterile in the female flower.
