racier is not derived folely from the number 
of fiamens, fuch variations may be of ,Jefs 
confequence. The hawthorn (cratzegus) and 
pheafant's eye (adonis) exhibit marks of the 
claffes Icofandria^ twenty males, and Poly* 
andria, many males, the hawthorn having it's 
ftamens fixed to the calyx, and thofe of the 
adonis being placed on the receptacle. In 
the clafs Didynamia, two-powers, Tetrady- 
narnia, four-powers, and Monadelphia, one-? 
brotherhood, the orders or fubdivifions, na 
longer depending on the number of piffils, 
will require fome farther explanation. In the 
fourteenth clafs, two-powers, the genera are 
divided into two orders, the firft diftinguifhed 
by the feeds being placed within the calyx 
without any other covering; the fecond by 
the feeds being contained by a pericarp, or 
feed-veffel: from thefe different circumftances 
the orders derive their names of gymnofper-* 
mia, feed-naked, and angiofpermia, feed- 
covered. The dead-nettle (lamium) and 
fnap-dragon (antirrhinum) are good fpeci-? 
mens of both orders, and alfo of the chfs 
two-powers. The orders of the fifteenth
