| The Hippomaneae (Euphorbiaceae) are revised for Malesia. Only Excoecaria and Homalanthus are excluded. A key to all Malesian genera is provided. The generic concepts applied differ markedly from previous treatments for the region with the following genera accepted: Balakata, Falconeria, Gymnanthes, Microstachys, Sapium, Shirakiopsis, Stillingia and Triadica. All of these genera show peculiarities in biogeography and ecology, which are discussed. Among these genera only Stillingia is kept as traditionally used. Balakata (based on Sapium sect. Pleurostachya) and Shirakiopsis (based on Sapium sect. Parasapium but excluding its type) are described as new genera; Falconeria, Microstachys and Triadica are re-established as distinct genera having been treated as... |

| Shirakia (Euphorbiaceae) was described by Hurusawa (1954) with three species. It was named after Croton shiraki, a nomen nudum used by Siebold & Zuccarini (1843) for the species currently known as S. japonica (Siebold & Zucc.) Hurus. Kruijt (1996) transferred five additional species to Shirakia. Esser et al. (1998) showed that S. japonica, the type, differs in several characters from the remainder of the genus. In a phylogenetic analysis they concluded that all additional species have to be removed to other genera ( Shirakiopsis Esser ined., Triadica Lour.), with Shirakia remaining as a monotypic genus endemic to Japan and adjacent East Asia. The name, however, is a later homonym of Shirakia S. Kawasaki, a fern fossil described in 1934 from South... |
