Vernacular names

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.


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]

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

Dioclea albiflora R.S.Cowan
Dioclea apurensis Kunth
Dioclea burkartii R.H.Maxwell
Dioclea fimbriata Huber
Dioclea guianensis Benth.
Dioclea holtiana Pittier ex R.H.Maxwell
Dioclea lasiophylla Mart. ex Benth.
Dioclea lehmannii Diels
Dioclea macrantha Huber
Dioclea ovalis R.H.Maxwell
Dioclea paniculata Killip ex R.H.Maxwell
Dioclea sericea Kunth
Dioclea vallensis R.H.Maxwell
Dioclea virgata (Rich.) Amshoff

Species transferred to Macropsychanthus include:

Dioclea grandiflora → Macropsychanthus grandiflorus
Dioclea macrocarpa → Macropsychanthus macrocarpus
Dioclea schimpffii → Macropsychanthus schimpffii


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]
