MALVACEÆ. 95 
Malvavisceæ (Malvaviscus), whose fruit is partly fleshy the cells 
being oppositipetalous. 
XI. ROSE MALLOW SERIES (77, Ketmies). 
The Rose Mallows' (figs. 152-161) have flowers analogous to those 
of the Mallows. Their calyx is gamosepalous with five valvate lobes ; 
and the corolla, gamopetalous at the base and united with that of 
the androceum, is contorted in præfloration. The stamens form a 
tube with truncate or quinquedentate apex whence are detached an 
indefinite number of slender 
summits surmounted by a 
one-celled anther with longi- 
tudinal? dehiscence. The 
gynæceum is composed of an 
ovary with free alterni- 
petalous cells. In the inner 
angle of each cell a placenta 
is seen supporting either 
an indefinite number of 
ovules arranged in two ver- 
tical series, or only three or 
four ovules. The fruit (fig. 
159), around which the calyx 
and epicalyx persist, is loculicidal, and at maturity allows reniform 
seeds to escape, often more or less abundantly covered with hairs 
and enclosing under their coats a thick embryo with large coty- 
ledons more or less folded upon themselves. Between their folds is 
often seen an inconsiderable mucous albumen. The Rose Mallows 
_are arborescent, frutescent or herbaceous plants, glabrous, tomentose or 
Hibiscus roseus..
