verse section were four, of these, the two most distinct, 
obviously supply the two most distinct stamens, both of which 
were perfectly polliniferous. The two remaining were indis- 
tinct and belonged to what I consider an undeveloped sta- 
men, with the sides of which they correspond, no axillary 
bundle existed, nor was there any appearance of one corres- 
ponding to the third stamen, which was exceedingly rudi- 
mentary. 
In another instance however, as distinct a vessel as any in 
the column corresponded with one of the broader teeth, 
and terminated just beneath its apex. In this instance also 
the most rudimentary stamen was supplied. 
In another longitudinal section of 1 a column the bundles 
were as follows, one for the perfect stamen, one ditto for its 
perfect stigma, one for a barren stamen, opposed to this was a 
short distinct bundle, one for an abortive one. 
On the subject of the vascular distribution for the supply 
of the parts of the genitalia, I can say nothing with the re- 
quisite confidence.
