THE PRINCIPLES OF BOTANY. 
By Professor James Buckman, F.G.S., F.L.S., &c. &c. 
(Continued from p. 186.) 
We now commence a description of that division of the 
large Exogen class, to which the term Hypogynous Exogens 
has been given, the definition of which is that the stamens 
grow from the base of the ovarium , as distinguished from the 
Perigynous Exogens , in which the stamens are growing upon 
some body surrounding the fruit , and Epigynous Exogens , 
when these organs grow from the apex of the fruit ; and of 
the three cases we would recommend as examples the fol¬ 
lowing : 
Hypogynous flower .—Common stocks and gilliflowers, 
buttercups. 
Perigynous flower. —Boses, apples, pears, plums, prim¬ 
rose. 
Epigynous flower. —Dandelion,^daisy, bedstraws. 
These, it will be seen, can easily be got at in town or 
country, and will well repay for an examination of the inser¬ 
tion of the stamina. Professor Lindley, speaking of this 
subject, says: 
“ The hypogynous insertion of the stamens has been re¬ 
garded by the French school of botanists as one of very 
great systematical importance, and it does seem to collect to¬ 
gether a large mass of plants, the genera of which have a 
great resemblance to each other. If we assume that the 
entire separation of the calyx and corolla from the stamens is
