Poranthereae

Andrachne Meineckia Notoleptopus Pseudophyllanthus Poranthera Phyllanthopsis Actephila Leptopus Poranthereae is a tribe in the plant family Phyllanthaceae.

The circumscription and classification of Poranthereae were substantially revised following phylogenetic analysis of DNA sequences from members of the family Phyllanthaceae.

[2] Within Poranthereae, groups of related genera are strongly correlated with habitat and geographical distribution.

Petals present or absent, often partly adnate to the nectary disk, equal to the sepals or shorter, white or greenish, usually larger in staminate than in pistillate flowers.

Anthers latrorse, at least in bud, opening by longitudinal slits, or in Poranthera, by pores.

[3] The type genus for the tribe is Poranthera, which was so named because the anthers open poricidally rather than by longitudinal slits.

[5][6] These authors considered Poranthereae to be part of Euphorbiaceae sensu lato, a taxon that is now known to be paraphyletic.

Poranthaceae, as currently understood, was first recognized in phylogenetic analyses of DNA sequences of selected genes.

[9] The existence of this clade was not entirely unanticipated and had been at least partially suggested in several studies based on morphology.

[1] In 2007, a phylogeny of Poranthereae was presented by Vorontsova et alii, based on DNA sequences of matK and ITS.

In 2008, based on molecular phylogenetic studies, Vorontsova and Hoffmann published a revised classification of the tribe.
