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]
- 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
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]
