“ are abfent, it is owing to fome circumflance that 
determines the fap into other channels, and thereby 
“ prevents the expanfion of the part.” 
I faid this would, perhaps, be thought to amount 
to more than a conjedture ; becaufe, befides its proba- 
bility from the circumftances I have ftated above, it 
will perfedly explain another well attefted phaeno- 
menon in the clafs Dioecia, that is fcarce to be ac- 
counted for on any other fuppofition. viz. that a male 
plant has, at a certain age, been found to change to 
a female one, and v/ce verfa^ and alfo to bear flowers 
of both fexes, to which I may add another which 
I have myfelf obferved in the Monoecious plants, 
Zea and Ricinus, where I have often found fpikes 
of fruit breaking out amongft the male flowers, though 
they commonly come out feparate from them in 
another part, of the plant. 
If there be any weight in the arguments I have 
here ufed in fupport of this fuppofition, the general 
conclufion will be this, that the flowers of all vege- 
tables whatfoever are hermaphrodite in their origi- 
nal conilrudion, though both the organs do not ap- 
pear in all cafes.
