toi, or that part of the flower which moft at- 
tracts our notice, confifting generally of beau- 
tifully coloured leaves. Linneus defines it to 
be formed from the inner rind of the plant, 
as the Calyx is from the outer ; it's leaves are 
called Petals, a term which fhould be remem- 
bered, as it is neceifary to prevent confufion 
betwixt the green leaves of the plant, and the 
coloured ones of the flower. By the number, 
divifion, and lhape of the Petals, the different 
kinds of Corols are diftinguifhed ; a Corol is 
called one-petalled, when it confifts only of 
one piece ; two, three, or more petalled, ac- 
cording to the number of pieces of which it is 
compofed. The flower of common Polyan- 
thos is one-petalled, although, on the firft 
view, from its divifions round the margin, it 
appears to confift of five petals. The beft 
way of knowing, whether a flower confifts of 
one or more petals, is to attempt to take them 
off all together. The one-petalled flowers, be 
their divifions ever fo deep, have their petals 
united together at the bafe, forming a tube, 
fometimes very long, as in Polyanthos, or 
very fhort, as in Veronica. In flowers of 
many petals they are fixed by the claw to dif- 
ferent parts of the fructification, which circum-
