  • Hymenospron Spreng.
  • Lepidamphora Zoll. ex Miq.

Taxonomy edit

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 edit

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:

Chemistry edit

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]
