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.
