the Pea (f. 5.), Bean, Lupin, and others of the same 
family.— 
It consists of five petals, which vary in size and 
shape, one petal is usually larger than the rest, and is 
called the standard, or vexillum (v.); two others are 
placed opposite to this, which are narrower and smaller, 
and are called the wings or ale (a.), and two others 
will be found within the wings, partly united together, 
so as to resemble a boat; these two are called together 
the keel, or carina (¢.). This form of corolla is some- 
times called the Papilionaceous, or Butterfly-shaped 
corolla. 
51. The monopetalous, or gamopetalous corolla, (or 
petals united), is also regular or irregular according as 
it is composed of parts which are equal or unequal. 
The monopetalous regular corolla may be bellshaped, 
or campanulate, as in the Campanula (pl. 18. f. 12). 
Funnel-shaped, or infundibuli form, as in the Tobacco 
(pl. 14. f 6.); in which the tube is narrower and 
longer than in the former kind, 
Salvershaped or hypocrateriform, as in the Primrose, 
in which there is a tube, and the limb is spread out 
flat, like a salver (pl. 14. f. 7.). 
The wheel-shaped or rotate corolla, differs in having 
a very short tube (f. 10.). 
52. Of the monopetalous irregular corolla, the two 
principal forms are the ringent, or labiate, or two 
lipped corolla; as in the dead Nettle (pl. 18. f. 6.), 
Sage, in which the corolla is divided in two principal 
lobes, called lips; and personate or mask-like corolla as 
seen in the Snapdragon (pl. 14. f.8.); this differs from
