. Botany for young people and common schools. Botany. KINDS AND FORMS OF LEAVES. 47 Oval; broader than oblong, and with a flowing outline, as in Fig. 00. Ovate ; oval, but broader towards the lower end; of the shape of a hen's egg cut through lengthwise, as in Fig. 91. Orbicular or Round ; circular or nearly circular in outline, as in Fig. 93. u. Linear. Lance- Oblong. shaped. Heart-shaped. Of these the common- 133. Some leaves taper downwards more than upwards, est forms are the Oblanceolate, or Inversely lance-shaped; that is, shaped like a lance with the point downwards, as in Fig. 94. Spatulate ; roundish above, and tapering into a long and narrow base, like the old form of the apothecary's spatula, Fig. 95. Obovate, or Inversely ovate; that is, ovate with the narrow end at the bottom of the leaf, as in Fig. 96. Cuneate or Wedge-shaped; like the last, but with the sides narrowing straight down to the lower end, in the shape of a wedge, as in 134. Of course these shapes all run into one another by imperceptible degrees in different cases. The botanist merely gives names to the principal grades. Inter- mediate shapes are described by combining the names of the two shapes the leaf in question most resembles. For example : — Lance-linear, or linear-lanceolate, means between linear and lance-shaped. Lance-oblong, or oblong-lanceolate, means between oblong and lanceolate in shape. Ovate-lanceolate, between ovate and lance-shaped; and so on. 135. Or else a qualifying word may be used, as somewhat ovate, slightly heart- shaped, and the like. Thus, Fig. 92 is ovate in general form, but with the base a little notched, i. e. somewhat heart-shaped. It is one of the kinds which depend upon.
