Fia. xm. Fio. Xn.—Eadiately or palmately compound leaf. Fio. XIII.—Pinnately compound leaf. Forms of Bladei—The forms of the blade may be concisely ar- ranged as follows (Fig. XIV): 1. Bound (orbicular), with a circular outline, or nearly so. 3. Ovate, which is longer than broad, and has a broader base and a narrower apex (thereverse of this is the olovate). When the base is divided into two rounded lobes the leaf is heart-shaped. Related to the ovate is the rhomlic leaf with more or less angled sides. The triangular leaf is another modification in which the base is truncate (cut off). The very short and broad modification of the heart-shaped blade is the hidney-shaped leaf (reniform). The nar- row ovate is the lanceolate form, while its reverse is the ollanceo- late (spatulate). 3. elliptical, which is longer than broad, has base and apex equal, and sides rounded. 4. Olhng, which is two to three times longer than broad, with straight, parallel sides. Varieties of this are the linear, which is very narrow and long: when this is rigid and sharp at the apex.
