Acute, ending in an acute angle or not prolonged point; Fig. [134].
Obtuse, with a blunt or rounded apex; as in Fig. [135], etc.
Truncate, with the end as if cut off square; as in Fig. [136].
Retuse, with rounded summit slightly indented, forming a very shallow notch, as in Fig. [137].
Emarginate, or Notched, indented at the end more decidedly; as in Fig. [138].
Obcordate, that is, inversely heart-shaped, where an obovate leaf is more deeply notched at the end (Fig. [139]), as in White Clover and Wood-sorrel; so as to resemble a cordate leaf inverted.
Cuspidate, tipped with a sharp and rigid point; as in Fig. [140].
Mucronate, abruptly tipped with a small and short point, like a mere projection of the midrib; as in Fig. [141].
Aristate, Awn-pointed, and Bristle-pointed, are terms used when this mucronate point is extended into a longer bristle-form or slender appendage.
The first six of these terms can be applied to the lower as well as to the upper end of a leaf or other organ. The others belong to the apex only.
