seeds. In Nove

“Yet while this second Bryony was literally covered with fruit, the old plant, 
distant from it only a few yards, bore neither more nor less fruit than it did in the 
preceding years. We cannot say then that in both fecundation may have been 
effected by insects carrying pollen of the species, since it is evident that they 
would have equally taken it to both, and that both in consequence would have 
dispositions ; in other terms, by yeritable idiosyncrasies.” 
At the base of the petals of the female flower of Bryonia dioica may 
be seen a sort of globular gland surrounded by hairs. This would 
seem to answer to the anther of the male.. It is very rarely if ever ab- 
sent, and sometimes takes a slight twist, like the normal anthers. It 
is a very minute object generally. I have had some difficulties in 
carrying out my experiments on this plant, but may mention one that 
is decisive. I gathered, several times, branches of the female plant 
with the flowers in bud, and kept them in water under a propagating- 
glass till they opened. When examined, one or two grains of polien 
were found in nearly every flower, probably produced by these gland- 
like bodies to which they were attached. The ovaries of most of the 
flowers became swollen, but eventually dropped off. One peculiarity 
of the plant is, that the opposite sexes are generally found in groups,
