GENERAL DESCRIPTION OF THE COROLLA. 231 
Wallflower and Pink (fig. 475) ; the narrow portion is then termed 
the wnguis or claw, 0, and the expanded portion the limb, 1, and 
the petal is said to be wngwiculate or clawed. In this particular, 
petals must be considered to resemble the leaves more than the 
sepals do, as the latter organs are almost without exception 
sessile, or destitute of claws. 
The outline of the petals, like those of the sepals and leaves, 
is subject to great variation. Thus, they,may be linear, oblong, 
lanceolate, elliptic, ovate, cordate, &c. The application of these 
terms having been already fully explained when speaking of 
leaves, need not be further alluded to. The condition of their 
margins also, the mode in which they are divided, and their

terminations, are also indicated by the same terms as those 
previously described under similar heads in our chapter on 
Leaves. Thus the petals may be dentate, serrate ; cleft, partite, 
sected ; acute, emarginate, &c. The petals are not however 
liable to any further division than that of the primary one ; thus, 
although sometimes pinnatifid, or pinatipartite, &c., they are 
never bipinnatifid, or bipiniatipartite. One term is occasionally 
used in describing the condition of the margins which has not 
been alluded to when speaking of the leaves ; thus the petals are 
said to be fimbriated or fringed, as in some species of Dianthus 
(figs. 474 and 475, /), when they present long thread-like processes 
at their margins.’ 
Again, the petals may be either flat, as is usually the case, 
or concave, tubular, boat-shaped, &c. These terms sufficiently 
explain their meaning; but a few anomalous forms of petals
