摘要:

长期以来,白毛算盘子(Glochidion arborescens Blume)被认为广布于中国云南西部至南部地区。该研究基于多年野外考察及标本查阅工作发现,由于白毛算盘子在中国的分布实为标本错误鉴定所致,相关错误鉴定的标本绝大部分属于绒毛算盘子 [G. heyneanum(Wight & Arn.)Wight],少部分属于里白算盘子(G. acuminatum var. acuminatum Müll. Arg.)、毛果算盘子(G. eriocarpum Champ. ex Benth.)、艾胶算盘子 [G. lancolarium(Roxb.)Voigt]或厚叶算盘子 [G. zeylanicum var. tomentosum(Dalzell)Trimen]等物种,故在此将白毛算盘子在中国的分布予以排除。另外,对白毛算盘子进行了后选模式指定,并提供了白毛算盘子与相关混淆种的物种检索表。

Abstract:

The species Glochidion arborescens Blume has long been considered to be widely distributed in Yunnan Province, China. Based on years of extensive specimen examinations and field investigations, we demonstrated that all the Chinese specimens previously identified as G. arborescens mostly belonged to G. heyneanum(Wight & Arn.)Wight, while several others belonged to G. acuminatum var. acuminatum Müll. Arg., G. eriocarpum Champ. ex Benth., G. lancolarium(Roxb.)Voigt or G. zeylanicum var. tomentosum(Dalzell)Trimen. G. arborescens is not found to China and thus the distribution of the species in China is excluded. In addition, a lectotype of G. arborescens is specified, and a species key of G. arborescens and relevant misidentified species is provided.
