PARALLEL-VEINED LEAVES. 89 
18. Digitate (finger-shaped), having narrower and deeper 
segments than the palmate, as in the hemp. 
19. Pedate (foot-shaped). The same as palmate, except that 
the two lateral lobes are themselves subdivided, as in the 
peony and passion-flower. 
20. Laciniate (gashed), the veins and veinlets separate, as it 
the blade were cut and gashed with scissors. Ex. Ranunculus. 
21. Peltate (shield-like), the veins radiating in all directions, 
and all connected by intervening tissue. This form is gener 
ally also orbicular, and appears to result from the union of the 
base-lobes. Ex. Podophyllumn peltatum, Tropeolum, Brasenia. 
22. Reniform, broad-ovate, broad-cordate, &c., may also result 
from the radiate veining. 
234. The form of PARALLEL-VEINED leaves is less diversified 
than that of the preceding classes, being 
23: Linear, when the veins (and fibres) are straight, as in the 
grasses. This form may also occur in the feather-veined leaf 
_ by an equal development of all the veinlets as in Linaria vul- 
garis, &c. 
FIG. 31. —28, 24, 25, figures of leaves with parallel veins ; 2—10, margins of leaves. 
24. Oval, lanceolate, oblong, or some kindred form, when the 
veins are curved, as in Carex, Cypripédium, Orchis, &c., or it 
may be 
25. Cordate, when some of the lower veins are curved back- 
wards and then upwards, as in Pontaderia, and even sagzttate, 
when they are directed downwards at the base, as in the Sagit- 
taria. 5;
