Abstract

The breadfruit genus (Artocarpus J.R.Forst. & G.Forst., Moraceae) has 16 species in Singapore, 14 of them native. The following taxonomic changes in Artocarpus subgenus Pseudojaca Trécul, based on recent phylogenetic work, are presented with diagnostic characters. Artocarpus griffithii (King) Merr. is reinstated as distinct from A. lamellosus Blanco (which is called A. nitidus Trécul in the earlier literature), also requiring the reinstatement of the following taxa not found in Singapore: A. borneensis (Merr.) F.M.Jarrett, A. humilis Becc., A. vrieseanus Miq. var. subsessilis F.M.Jarrett and A. xanthocarpus Merr. Artocarpus dadah Miq. is reinstated as distinct from A. lacucha Roxb. ex Buch.-Ham., thereby necessitating the reinstatement of the following taxa not found in Singapore: A. fretessii Teijsm. & Binn. ex Hassk., A. ovatus Blanco, and A. vrieseanus var. refractus (Becc.) F.M.Jarrett. Artocarpus gomezianus Wall. ex Trécul is restricted to the type subspecies, and A. zeylanicus (F.M.Jarrett) E.M.Gardner & Zerega, formerly a subspecies, is elevated to species level. Thirteen lectotypes and two neotypes are designated.

伪槐亚属(桑科)的分类更新，特别关注新加坡的分类群

面包果属。& G.Forst。(Moraceae)在新加坡有16种，其中14种为本地种。本文根据近年来的系统发育研究，提出了以下在树属Pseudojaca tracimcul的分类变化及其诊断特征。阿托卡普斯·格里菲斯(国王)作为与A. lamellosus Blanco(在早期文献中称为A. nitidus tracimcul)不同的物种而被恢复，还需要恢复以下在新加坡未发现的分类群:A. borneensis (Merr.)。f.m.j rett, A. humilis Becc。， A. vrieseanus Miq。黄果仁和黄果仁。Artocarpus dadah Miq。恢复为不同于A. lacucha Roxb。Buch.-Ham交货。，因此有必要恢复下列在新加坡没有发现的分类群:A. fretessii Teijsm。& Binn。Hassk交货。(1)、卵形花和折射花(2);F.M.Jarrett。山竹。原属亚种的a . zeylanicus (f.m.j jarrett) E.M.Gardner & Zerega被提升为种。指定了13种类型和2种新类型。
