摘 要 :琴叶风吹楠(Horsfieldia pandurifolia Hu)自1963年命名发表以来,其分类学位置一直存在争议。本文以中国野生肉豆蔻科(Myristicaceae)11个种为材料,从形态学、油脂化学和分子遗传学方面对琴叶风吹楠分类学位置进行研究。结果表明,琴叶风吹楠与H.macrocoma ssp. prainii的形态特征高度一致,与中国风吹楠属其它类群,以及红光树属和肉豆蔻属植物在形态学和油脂化学方面存在决定性差别,在分子遗传学方面存在较大差异。支持将H.pandurifolia并入H.macrocoma ssp. prainii,以H.macrocoma为模式种建立Endocomia属,琴叶风吹楠的学名变更为Endocomia macrocoma(Miq.) de Wilde ssp. prainii(King) de Wilde。
Abstract:Horsfieldia pandurifolia Hu was discovered in 1963. There have been many controversial opinions about its taxonomic position. The taxonomic position of H.pandurifolia was studied based on plant morphology, chemical taxonomy and DNA molecular marking from 11 wild species of Myristicaceae in China. H.pandurifolia was in accordance with H.macrocoma ssp. prainii, and was distinguished from Horsfieldia, Knema and Myristica obviously. These evidences supported that H.pandurifolia was reduced to H.macrocoma ssp. prainii effectively and the genus Endocomia was established with the type species H.macrocoma. We suggested that Endocomia macrocoma(Miq.) de Wilde ssp. prainii(King) de Wilde takes place of the sciential name H.pandurifolia Hu.
