MODIFICATIONS OF INCISED LEAVES. 167 
are again divided in a similar manner, tripinnatiyid, tripinnati- 
partite, or tripinnatisected. Or, if the lamina is still further 
divided, the leaf is said to be decomposed or laciniated. 
Certain modifications of these varieties have also received 
special names ; thus, when a pinnately-veined leaf is deeply 
divided, and the divisions are very close and narrow like the 
teeth of a comb (fig. 327), it is said to be pectinate, as in the 
Water Milfoil ; when the terminal lobe of a pinnately-veined 
leaf is large and rounded, and the lateral lobes which are also 
more or less rounded become gradually smaller towards the 
base, it is lyrate or lyre-shaped, as in the common Turnip (fig. 
328) ; when the terminal lobe is triangular, and the other lobes 
which are also more or less of the same shape have their points 
directed downwards towards the base of the lamina, as in the 
Fie. 332%

Dandelion (fig. 329), the leaf is said to be runcinate ; or when 
a lyrate leaf has but one deep recess on each side, so that it 
resembles a violin in shape, it is termed panduriform or fiddle- 
shaped, as in the Fiddle Dock (fig. 380). 
The above terms are those which are employed to define 
incised feather-veined leaves ; but when the blades are palmately- 
veined and incised, other terms are used according to the degree 
of division. In describing such leaves, the terms bifid, trifid, 
quinquefid, &c., bipartite, tripartite, &c., bisected, trisected, &c., 
are employed according to the number of their lobes, partitions, 
or segments, as already noticed; or the terms palmatifid, 
pumatipartite, palmatisected, derived from the direction of the 
veins, combined with that of incision, are used. Special names 
are also applied to certain modifications of these palmately- 
veined Jeaves as with those which are pinnately-veined. Thus, 
when the blade of such a leaf has five spreading lobes united at
