A segregate genus of 50 New World species, mostly tropical, but with a few near-hardy species and hybrids, one of which was treated by Bean as Abutilon megapotamicum. Erected by Donnell, Ballard & Cantino (2012) on the basis of molecular and morphological evidence, in particular petals with impressed vein, and four or more ovules per carpel.
For a brief note on the taxonomy of the (notoriously problematic) genus Abutilon s.l., see the entry for that genus.
We have published this stub genus article as part of a wider reorganisation of Malvaceae articles. This is part of a programme of work beginning in early 2025 to bring the nomenclature of articles in line with modern treatments. Historic Bean text will appear under its correct modern name, with appropriate synonymy, until we have funding to update the articles entirely. A full account of this genus will be provided when funds are available. If you would like to sponsor this work please write to editor@treesandshrubsonline.org
