FIGURE 2. Legume leaf morphology terminology for groups 1–5 in the key. Group 1: A, B, C and E; group 2: F; group 3: D, G and L; group 4: J and M; group 5: N. A: simple leaf (pulvinus only at petiole base); B: leaf unifoliolate (pulvini at petiole base and apex); C: leaf simple and bilobed (common in Bauhinia); D: leaf (digitately) trifoliolate; E: leaf petiole expanded into a flattened phyllode, the terminal leaflets caducous (typical of Acacia sensu stricto); F: leaf bifoliolate; G: leaf (pinnately) trifoliolate (often with stipels at the base of the leaflets, as seen in most phaseoloid legumes); H: detail of the stipels at leaflet bases; J: leaf paripinnate (i.e. once pinnate and terminating in a leaflet pair), and in this example the leaf rachis winged and an extra-floral nectary between each leaflet pair (this is a typical Inga leaf); K: detail of the extra-floral nectaries; L: leaf palmate, with five or more leaflets (typical of most Lupinus species); M: leaf imparipinnate (i.e. once pinnate and terminating in a single leaflet); N: leaf bipinnate (typical of all mimosoid legumes except Inga).
