LECTURE II. 
A Flower differed: the different kinds of Fulcra end 
Inflorefcence explained, 
' . I . 
The feven parts of frucTification, with all 
their varieties, being well underftood, the dif- 
fection of a few flowers will be both armifing 
and inftruftive. The Veronica and Crowfoot 
are plants which may be found near every 
houfe, and afford fpecimens of the Perianth 
kind of calyx ; the earth-nut (bunium) is an 
mftance of the Involucre, and at the fame time 
the fingle florets fliow the Perianth, although 
fo very minute that it is liable to efcape the 
notice of common obfervers. The male bloom 
of walnut (juglans) mows the Ament ; the 
narcilfus the Spathe. The other three kinds 
of calyx, the Glume, the Calyptre, and the 
Volve, as they belong to peculiar and difficult 
claffes of plants, would at prefent only per- 
plex ; the ftudy of them will be therefore 
better deferred till the pupil is farther ad- 
vanced in his knowledge of botany.
