The leaf size spectra revealed that nanophylls were dominant with 26 (72.22%) species followed by microphylls with 4 (11.11%) and mesophylls with 3 (8.33%) species (Fig.
(1) = Abundance; (2) = Life form; (3) = Leaf size; (4) = Habitat; (5) = Leaf appearance; A = abundance; Ch = Chamaephytes; Cm = Common; D = Dry; G = Geophytes; H = Hemicryptophytes; L = Leptophyll; M = Moist; Mac = Macrophyll; Mes = Mesophyll; Mic = Microphyll; N = Nanophyll; Re = Rare; S = simple; Th = Therophytes.
As a whole Chameophytes were dominant and their percentage were 26.38 followed by microphylls, nanophylls and mesophyll.
It was followed by microphylls and nanophylls having the contribution of 18.37, and 16.33% respectively (Table 2).

Using Raunkiaer's scale for the classification of leaf size, leptophylls are leaves have a surface area less than 0.04 sq in (25 sq mm) (the term is also used for the plants that bear them); nanophylls are leaves between 0.04 and 0.4 sq in (26 and 225 sq mm); microphylls are leaves between 0.4 and 28 sq in (226 and 18,225 sq mm); macrophylls are from 28 and 254 sq in (18,226 and 164,025 sq mm); and megaphylls are leaves that have a surface area greater than 254 sq in (164,026 sq mm).
There is also a tendency to reduce leaf size: small leaves, microphylls, which are rare in tropical rainforests become more common as rainfall decreases.
