Bound (orbicular), with a circular outline, or nearly so. 2. Oeate, which is longer than broad, and has a broader base and a narrower apex (the reverse of this is the olovate). When the base is divided into two rounded loljes the leaf is Jieart shoped. Related to the ovate is tlie rhombic leaf with more or less angled sides. (tr\ea.[ is anotlier modification in which lliebase Xitruncate (cut off). The very short and broad modification of the heart-shaped blade is the hidney-shaped leaf (reniform). The nar- row ovate is tlie lanceolate form, while its reverse is the oblanceo- lale (spntulate). 3. Elliptical, which is longer than broad, has base and apex equal, and sides rounded. 4. Oblong, whicli 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.
