Abstract

We review the species diversity of the Asian genus Meiogyne (Annonaceae) in Thailand. Four new species, M. anomalocarpa, M. chiangraiensis, M. gardneri, and M. maxiflora, are described. Meiogyne anomalocarpa has the widest distribution of any Meiogyne species in Thailand, but the other three species are narrowly distributed. Meiogyne anomalocarpa and M. maxiflora have the axillary inflorescences typical of the genus, but in M. chiangraiensis and M. gardneri the inflorescences are flagelliform and arise from the lower trunk, a morphology previously unreported from members of this genus. The presence of M. chiangraiensis in northern Thailand extends the range of the genus significantly northward. Meiogyne caudata is reported as new to the flora of Thailand. Several Meiogyne specimens from southernmost Thailand previously identified as M. virgata in the past by various workers were found to be more similar to M. kanthanensis, recently described from Perak, Peninsular Malaysia. A key is provided for the eight species currently recognized as occurring in the country.

标题泰国减数榕属植物订正及四新种记述

本文综述了亚洲减数榕属植物在泰国的物种多样性。描述了4个新种:M. anomalocarpa、M. chiangraiensis、M. gardneri和M. maxiflora。其在泰国分布最广，其余3种分布较窄。Meiogyne anomalocarpa和M. maxiflora的花序具有本属典型的腋生花序，但M. chiangraiensis和M. gardneri的花序是鞭毛状的，起源于下树干，这种形态以前未在本属成员中报道过。在泰国北部的chiangraiensis的存在使该属的范围向北显著扩展。据报道，Meiogyne caudata是泰国植物区系的新种。来自泰国最南部的几个先前被各种工作人员鉴定为M. virgata的Meiogyne标本被发现与最近在马来西亚半岛霹雳州描述的M. kanthanensis更相似。提供了目前在该国公认的八种物种的钥匙。

期刊介绍： Thai Forest Bulletin (Botany) (TFB) publishes papers on plant taxonomy (especially of vascular plants), nomenclature, phylogeny, systematics, plant geography, and floristics, and in morphology, palynology, cytotaxonomy, chemotaxonomy, anatomy and other relevant disciplines. Priority is given to papers written by staff of the Forest Herbarium and by botanists working on the Flora of Thailand project. Limited space is available for other relevant papers. TFB is published twice a year, usually in June and December. Two free copies of the issue in which the manuscript is published are given to each author. The journal makes no page charges. All manuscripts are peer reviewed. Manuscripts are considered on the understanding that their contents have not appeared, or will not appear, elsewhere in the same or abbreviated form.
