Abstract

(Acanthaceae), a new species from a karst cave in southwestern Guangxi, China, is described and illustrated based on morphological and molecular evidence. This new species resembles Hemsl. in having elongated stems, cauline leaves, and more than one flower per rachis node, but it can be readily distinguished by its oblong, thickly papery leaf blades (vs. ovate, thinly papery); calyx 2-3 mm long (vs. ca. 6 mm long); and pubescent ovary and style (vs. glabrous). Photographs, an illustration, and a distribution map are also provided.

摘要

基于形态学和分子证据，描述并图示了中国广西西南部一个喀斯特洞穴中的爵床科（Acanthaceae）一新物种。该新物种与半枝莲属（Hemsl.）相似，具细长茎、茎生叶且每穗轴节上有一朵以上花，但可通过以下特征轻易区分：长圆形、厚纸质叶片（与卵形、薄纸质相对）；花萼长2 - 3毫米（与约6毫米长相对）；以及具柔毛的子房和花柱（与无毛相对）。还提供了照片、一幅插图和一张分布图。
