Melilotus leaflets. 
Mucronate, terminating in a short, soft point. Example: 
some Senna leaflets.

Anstate, with the apex terminating in a bristle. 
Emarginate, notched. Example: Pilocarpus. 
Retuse, with a broad, shallow sinus at the apex. Example: 
Petal of Rose gallica. 
Obcordate, inversely heart-shaped. Example: Oxalis. 
(c) Base or Lear.—Cordate, heart-shaped. Examples: Cat-

The bases of many leaves extend downward along the stem 
beyond the main point of insertion when they are called decurrent. 
If the base of the lamina is prolonged downward along the sides 
of the petiole to which it is joined, the leaf is said to have a 
winged petiole, as in Digitalis, 
The terms acute, tapering, attenuate, truncate, obtuse and rounded 
which have been defined under “Apex of Leaf’? are also applied 
to bases of like character.
