| Derris Lour. is revised for the Flora Malesiana region. In the introduction comments are given on some characters and the seedlings of D. trifoliata Lour. are described. The introduction is followed by a section ‘Notes on species’ in which the varieties of D. elegans Graham ex Benth. are described, including a new one from Celebes (var. celebica Adema) and a new one from Malaysia, Java, Borneo, the Philippines and the Moluccas (var. korthalsiana (Blume ex Miq.) Adema). Several other species are discussed at some length. A key to the species of Derris in Malesia is presented. The paper concludes with notes on aberrant specimens and excluded species. |

| Derris solorioides is described as a new species and illustrated. This species is only the second calciphilous and true-paniculate species of Derris ever recorded. The species was found in isolated and protected limestone areas surrounded by agricultural areas in Nakhon Sawan province, North-Central Thailand. It is characterized by its rather smaller flowers but with more ovules than other species of Derris, and 1-winged pods showing a dark-coloured pericarp around the seeds without thickening of the pericarp. The characters of the pods are similar to those found in Solori, a genus once synonymized with Derris and, therefore, the epithet ‘solorioides’ was assigned. This species appeared to be a distinct taxon in the molecular phylogeny, separate from its... |
