united at the summit of the branches or in the axils of the superior 
leaves in ramified clusters of cymes, generally biparous (fig. 222). 
There are also three other genera of this family known, natives of 
the same country and presenting the same general characters as the 
Schizolena rosea,

preceding. These are: Sarcolena (figs. 235-237), which instead of 
ten stamens, has an indefinite number, and the fruit of which is 
capsular with three cells; Schizolena (figs. 238-243), having two 
flowers in the same involucre, which is accrescent after præfloration, 
and then incised upon its edges (fig. 241), very numerous stamens, 
and an indefinite number of ovules in each cell (figs. 241, 242) ; 
Rhodolena, the involucre of which, also biflorous, is formed of two 
very small bracts, the stamens, indefinite in number, are inserted 
within a short circular disc, and each of the three ovary cells contain 
in the internal angle four ovules arranged in two ranks. 
Thus constituted this small family only contains nine or ten 
species ; it was established in 1806 by Doprurit-THovars, who alone 
has studied it much hitherto. We have just added a genus very 
incompletely known! and have besides described a species’ differing 

1 Scleroolena (H. Bx., in Adansonia, x. 234), 
which certainly belongs to this family, and which 
cannot be placed in any of the known genera, 
since we are only acquainted with the fruit. This 
is surrounded by a woody involucre, smooth with- 
out and within, of the form and size of a small 
egg. It presents a circular opening, the edge of 
which is furnished with a reflexed fringe formed 
of penicillate hairs. he fruit proper is very 
small in reference to the involucel; it is three- 
celled and polyspermous surmounted by the 
remains of a style with truncated apex. This 
genus, therefore, must be allied to those having 
multiovulate ovary cells, but it differs from all 
of them inasmuch as its involucre contains but 
one fruit and also by the singular character of the 
involucre itself,
