The different types of leaf tips or apexes (Fig.2b) are: rounded, that is, broad and semicircular
in outling; truncate, cut off square or nearly so; acutg ending in acute angle with the sides straight;
acumindte, pointed, but tapering lines incurved; obluse, blunt or narrowly rounde; retuse, slightly
notched at the apex (authors like Porter, 1967 and Henderson et al., 1963 defines retuse as bhaving a
broad shallow or rounde notch at the apex)emarginlated, prominently notched at the apex; obcordate,
with a sinus and two-rounded lobes; cuspidate, tipped with a cusp or sharp point; mucronate, abruptly
tipped by a small short point, aristate, the mucronate point is longer and more or less bristle-like; and
caudate, similar to aristate but the appendage broader and not bristle-like. Some or all of those terms
are also applicable to the base of the leaf and to other organs of the plant.
