Dioclea is a genus of flowering plants in the pea family, Fabaceae, that is native to the Americas. The seeds of these legumes are buoyant drift seeds, and are dispersed by rivers.

Taxonomy

A molecular phylogenetic study published in 2020 showed that when broadly circumscribed, Dioclea was not monophyletic. Many species were transferred to the genus Macropsychanthus . [2]

Species

As of August 2021, Plants of the World Online accepted the following species: [1]

Species transferred to Macropsychanthus include:

Chemistry

The A-type proanthocyanidin, epigallocatechin-(2β→7,4β→8)-epicatechin, together with epicatechin, luteolin 3′β-d-glucopyranoside, chrysoeriol 7β-d-glucopyranoside and 2-methylpentan-2,4-diol, can be found in the leaves of Dioclea lasiophylla . [3]

<span class="mw-page-title-main">Dalbergieae</span> Tribe of legumes

The tribe Dalbergieae is an early-branching clade within the flowering plant subfamily Faboideae. Within that subfamily, it belongs to an unranked clade called the dalbergioids. It was recently revised to include many genera formerly placed in tribes Adesmieae and Aeschynomeneae and to be included in a monophyletic group informally known as the dalbergioids sensu lato. The members of this tribe have a distinctive root nodule morphology, often referred to as an "aeschynomenoid" or "dalbergioid" nodule.
