| 英文摘要 |
A new species of Aristolochiaceae, Aristolochia geantha Z.R. Guo & Y.Fan Wang, from Southwest China, is described herein. Detailed scientific illustrations, color figures, and a key are provided. The species is morphologically proximate to A. petelotii, but can be readily distinguished by its flat, cupuliform calyx limb, which adaxially covered with golden or rusty villous hairs, a velvety pink upper tube, unusually elongated peduncle, which extends from the basal lignified stems, and distinctive stripe patterns radiating from the throat to the calyx limb margin. Comparative assessments with other congeners are provided to establish its unique taxonomic status within the genus. |
