A note on stomatal types and crystals in the leaves of Melastomataceae

摘要: Original data on leaf crystals and stomatal types in 25 genera of Melastomataceae are presented, discussed with reference to the classification family as modified by Van Vliet et al. (1981, this issue). The heterogeneity abolished subfamily Astronioideae is confirmed a separation Pternandra from Astronieae also justified basis anatomical data. characterized large styloids predominantly anomocytic stomata; combination characters occurs part Melastomatoideae (especially Miconieae). Most other polocytic diacytic stomata druses. subfamilies Memecyloideae Crypteronioideae remain rather heterogeneous anatomically, but evidence can be interpreted support mutual affinities.
