Schillerioideae
Schillerioideae includes ± 200 species.
Region: Central America and in the Atlantic Forest of Brazil.
Botany: shrubs, sarmentose.
Leaves are plinerved or pinnately nerved; leaf bases acute and may be decurrent with the petiole, and each leaf has a pair of callosities at the base.
Inflorescences: terminal; loose, lax, flowers loosely arranged.
Flowers: 4 stamens.
Fruits: free; trigonous or obovoid.
Taxonomy
Schilleria was first described as a genus by Kunth. Subsequent classifications did not recognize this group. Miquel lumped Schilleria into Artanthe. Callejas was the first to reconsider Schilleria at the subgenus level. Molecular sequence data and a much larger sampling presented here provide evidence for the distinctiveness and monophyly of this clade.
Plant theory
The tentative position for Schillerioideae is Subphase 6. Combined with it is the Clade around Piper betle form the south-eat Asia clade. Piper betle has strong aspects of decay, like that of the teeth.
