Abstract

A new species of Gesneriaceae, K.Huang & Z.X.Fu, , from the Feilaifeng Scenic Area of Longmen Mountain National Geological Park (Pengzhou, Chengdu City, Sichuan Province, China), is described and illustrated. Morphological and phylogenetic analyses provide robust evidence for its recognition as a new species. While morphologically most similar to Craib, phylogenetic reconstructions reveal its closest affinities with and (W. T. Wang) Z. J. Qiu. The new species is morphologically distinguished from by a suite of diagnostic characters: leaf shape (ovate to oblique-ovate vs. ovate to nearly orbicular), corolla throat (spotless vs. bearing two deep purple spots), and filament pubescence (translucent-puberulent vs. rust-brown puberulent). A distribution map and a comparative morphological table with , , and S. Z. Zhang & Z. Y. Liu, and a preliminary conservation assessment following IUCN criteria are provided.

摘要

描述并图示了一种来自中国四川省成都市彭州市龙门山国家地质公园飞来峰景区的新种苦苣苔科植物,即黄健 & 傅昭新。形态学和系统发育分析为其被认定为新物种提供了有力证据。虽然在形态上与 Craib 最为相似,但系统发育重建显示它与 和 (王文采)邱治业关系最为密切。该新物种在形态上与 的区别在于一系列诊断特征:叶形(卵形至斜卵形与卵形至近圆形)、花冠喉部(无斑点与有两个深紫色斑点)以及花丝柔毛(半透明柔毛状与锈褐色柔毛状)。提供了分布图、与 、 以及 张石泽 & 刘仲英的形态比较表,以及根据 IUCN 标准进行的初步保护评估。
