The more readily to distinguish this class from 
the sixth, in which the stamens are of equal length, 
it may be noticed that the flowers of the 15th class 
have always four petals, which form a cross, being 
d, by the lower parts of the filaments, into 
parcels or ee ds.

included i in this class all plants of which the parts 
any sense united above the 
mens are united, by the anthers, 
s, and the stamens inserted into the 
summit of the same part, just below it, was consid- 
ered as Gynandrous. Such a winnie is cara 
with great inconvenience, as in 1d, tal 
some species of which have a cipaitacate 
elevation of the germen, and others little or none. 
Tt is found, therefore, by far most convenient, not 
to consider such insertion or n at all as the 
character of a class or order, ones it takes place 
upon or above the germen ; or, in other ont unless 
the stamens st h

The 14th class has 2 Orders—Gymnospermia, seeds 
naked at the bottom of the calyx; as in Lavender, 
Mint, &c. And Angiospermia, where the seeds are 
enclosed in a seed vessel; as in the Fox Glove. 
None of the genera of the 14th or 15th Classes have 
more than one style. The characters of the Orders 
are, therefore, taken from <2 pericarp.
