Stomatal types of the genus Acacia (Fabaceae, Mimosoideae): an appraisal of diversity and taxonomic interest

Autor: J. Vassal, M. Saint-Martin, B. Grosso

Publikováno v: Botanical Journal of the Linnean Society. 116:325-341

The stomatal types of 102 species illustrating the different subdivisions of Bentham's classification of the genus Acacia were studied at two or three ontogenetic stages: first pinnate leaf to bipinnate leaves or to phyllode. Six stomatal types are r
