528 STERCULIACEA, 
That the petals are subjected to a process, the opposite of 
that which affects the stamens is probable, from the lateral 
ones being occasionally lobed, and from each series present- 
ing that gradual diminution of the size of the veins from 
the centre towards each side, that characterises the petals of 
Malvaceze and Cucurbitacee. The lateral ones also occa- 
sionally present oblique venation or such as 2 veins which is 
to a considerable degree incompatible with independent sim- 
ple organs, and certainly would be in this case anomalous; 
for all the petals being single and independent, should hare 
similarly organised vascular supplies, this also becomes pro- 
bable from their situation, for independent petals could not be 
so disposed without a greater anomaly than the complete divi- 
sion of ordinarily entire bodies. 
It appears to me not improbable, that this plant will 
lend some confirmation to the separation of Bombacine 
from Malvacez: the composition or enlargement of the 
Stamens towards the centre being remarkable, and the 
reverse of what might a priori be expected. - 
It will also turn out, perhaps, that the genera with 
fractuose anthers have highly compound ones, and such 4 
form is very likely to arise from the cohesion of a num- 
ber of pyxidate anthers.
