由于历史久远以及植物命名中的同物异名和同名异物现象的存在,《红楼梦》中的一些植物成为难以鉴定或易于混淆的疑难物种。本文从植物训诂和现代植物分类学角度考证了瓜子、樯木、麝、榆、百合香、黄松、凤尾和白海棠的原植物,为红楼梦植物文化研究提供基础资料。 Due to the long history and the existence of homonymy and the phenomenon of the same name in plants, some plants in A Dream of Red Mansions become difficult species that are difficult to identify or easily confused with. In this paper, the original plants of melon, alder, musk, elm, lily, ponderosa, phoenix and begonia were studied from the perspectives of plant abscess and modern plant taxonomy, which provided the basic data for the study of the plant culture of Amaryllis.
