Pinnately compound leaf with an odd terminal leaflet, e.g., pea. Pinnately compound without a terminal leaflet, e.g., Cassia. More than thrice pinnate, e.g., old leaves of coriander. The secondary axes produce the tertiary axis which bear the leaflets, e.g., Moringa. The central axis produces secondary axis which bears the leaflets, e.g., Acacia. Having leaflets on each side of an axis, e.g., Cassia. Such palmate compound leaf having three leaflets growing from same point, e.g., Oxalis, Vigna, Trifolium, Melilotus, etc.Ĭompound palmate leaf with four leaflets arising at a common point, e.g., Marsilea (a pteridophyte).Ĭompound palmate leaf with five or more leaflets arising at a common point, e.g., Gynandropsis pentaphylla, Bombax ceiba.Ī compound leaf having leaflets on each side on an axis or midrib. Palmate compound leaf with two leaflets, e.g., Prinsepia, Balanites. The compound leaves may be of several types.

Simple and Compound Leaves:Ī leaf which may be entire or incised to any depth, but not down to the midrib or petiole.Ī leaf made up of two or more leaflets, e.g., pea, and several other members of Leguminosae. Having leaf base prolonged down stem as a winged expansion or rib, e.g., Laggera pterodonta.Ī leaf with basal lobes so united as to appear as if stem ran through it, e.g., Aloe perfoliata.

Normally two stipules are developed at the base of a leaf petiole they may be foliaceous, e.g., in Lathyrus-, free lateral, e.g., in China rose adnate, e.g., in rose interpetiolar, e.g., in Ixora, Spergula- spiny, e.g., in Acacia, Euphorbia splendens tendrillar, e.g., in Smilax.
