Abstract

This is the report of a trip in 1968 conducted by Dr. M. Jacobs of the Rijksherbarium, Leiden, Netherlands, and Dr. B. Prijanto of the Forest Research Institute, Bogor, Indonesia. Financial support was given by the Netherlands Foundation for the Advancement of Tropical Research (WOTRO). Our sincere thanks are due to the liberal way in which this organisation made the enterprise possible, as a continuation of an expedition to the Philippines, on which a report by the same author is now in the press with the journal Blumea.

Abstract

This paper deals with the names and typication of the 34 species recognized in Malesia. Specimens important for the knowledge of the distribution of each species have been cited with their locality. Indexes to names and to all examined specimens are given. Ten new species are described: Castanopsis clemensii, densinervia, endertii, microphylla,, oligoneura, oviformis, paucispina, peduneulata, psilophylla, all from Borneo, and johorensis from Malaya. C. hypophoenieea and C. lucida are new combinations based on Quercus hypophoenieea v. Seem, and Alseodaphne lucida Nees in Wall, respectively. Castanopsis ebneri and woodii are reduced to evansii, hullettii to lucida, pachycarpa to rhamnifolia, conspersispina, to tungurrut, dispersispina to hypophoenieea, ridleyi partly to tungurrut and partly to megacarpa, kinabaluensis to foxworthyi, pearsonii to mottleyana, junghuhnii and schlenkerae to acuniinatissima. Castanopsis selangorensis A. Cam. is regarded as a doubtful species. The number of endemic species is for Malaya 5, Borneo 11, the Philippines 1; the total number of species, is for Sumatra 11, Malaya 17, Java 4, Borneo 20, the Philippines 4, Celebes 2, the Moluccas 1, New Guinea 1, the Lesser Sunda Islands none.
