Cotyledon size, shape, venation pattern and anatomy have been investigated in Faidherbia albida and 152 species of Acacia representing the three subgenera Acacia, Aculeiferum and Heterophyllum. Cell volumes of epidermis, palisade and storage tissue, stomatal frequency, stomatal index and frequency of stomatal types have been determined for F. albida and 12 species from each subgenus. The data obtained support the recognition of the subgenera of Acacia as separate taxa but provide no indication of their status. The evidence from cotyledons also supports the separation of Faidherbia from Acacia , and the amalgamation of the Acacieae and Ingeae.
