or three Mexican Melochias whose flowers however are much larger. 
The cells of the capsular fruit have in all the #e/ochias a loculicidal 
dehiscence; but in those which are distinguished under the name 
of Riedlea' they are also separated from each other sooner or later. 
Among the Dombeyas too, where the ovary is generally quinquelo- 
cular there are some species with dicarpellary gynæceum ; there has 
also been observed in Australia and described under the name of 
Dicarpidium monoicum,? a Melochia, having in its capsule only two 
bivalvate cells, which separate from each other at maturity. The 
genus Melochia contains fifty species’ inhabiting 
all the warm regions of the globe. They are Melochia pyramidata. 
herbaceous, or frutescent plants more rarely ar- = 
porescent, with alternate, narrow or cordate leaves 
generally dentate like a saw, glabrous, or more often 
covered with simple or stellate hairs. The flowers are 
terminal, or axillary, and arranged in glomerules or 
cymes which become a large compound terminal in- 
florescence when the upper leaves are replaced by 
bracts. These panicles are sometimes very much 
ramified in certain Asiatic and Oceanian Melochias which may have 
winged seeds, and of which the genus isenia'is made. Waltheria’ con- 
sists of Aelochias, whose gynæceum has only one carpel, and whose 
ovary, containing two ascending ovules, is surmounted by an eccen- 
tric style with stigmatiferous dilated or fimbriate penicillate apex ; 
some fifteen species’ may be reckoned, which are natives of all the 
varm regions of the globe.
