. The elements of botany for beginners and for schools. Botany. Obovate (Fig. 123) or inversely ovate, that is, ovate with the narrower end down. Cuneate or Cuneiform, that is, Wedge-shaped (Fig. 124), broad above and tapering by nearly straight Unas to an acute angle at the base. 136. As to the Base, its shape characterizes several forms, sucli as Cordate or Heart-shaped (Fig. 120, 129), when a leaf of an ovate form, or something like it, has the out- line of its rounded base turned in (forming a notch or sinus) where the stalk is attached.

Reniform, or Kidney- shaped (Fig. 131), like the last, only rounder and broader than long. Auriculate, or Eared, having a pair of small 126 126 127 and blunt projections, or ears, at the base, as in one species of Magnolia (Fig. 126). Sagittate, orarrotc-shaped, wliere such ears are acute and turned downwards, while the main body of the blade tapers upwards to a point, as in the common Sagittaria or Arrow-head, and in the Arrow-leaved Polygonum (Fig. 125). Hastate, or Halberd-shaped, when such lobes at the base point outwards, giving the shape of the halberd of the olden time, as in another Polygonum (Fig. 127). Peltate, or Shield-shaped (Fig. 132), is the name applied to a curious modification of the leaf, commonly of a rounded form, where the footstalk is attached to the lower surface, instead of the base, and therefore is natu- Fig. 121, oblanceolate; 122, spatiilate ; 123, obovate ; and 124, wedge-shaped, feather-veined, leaves.
