摘要

我们描述了在云南西南部双江县发现的一个独特的植物种群--Tuberowithania pengiana gen.新属和新种具有独特的形态特征组合，包括大块茎根、瓶形和密被短柔毛的深紫红色花、密被短柔毛的紫红色花丝，以及黄白色、卵圆形的浆果，由 10 肋增生花萼紧密覆盖。基于四个 DNA 标记（nrITS、trnL-F、waxy、LFY）的组合矩阵进行的分子系统发育分析表明，T. pengiana 被深深地嵌套在 Withaninae 亚部类中。它与 Archiphysalis chamaesarachoides 是姊妹关系，但支持度较弱。

Tuberowithania pengiana (Withaninae, Physalideae, Solanaceae), a new species and genus from southwest Yunnan, China

We describe a small population of remarkable plants found in Shuangjiang County, SW Yunnan, as Tuberowithania pengiana gen. & sp. nov., a unique genus within the subtribe Withaninae, tribe Physalideae of the Solanaceae family. The new genus and species feature a distinctive combination of morphological traits, including a large clumped tuberous root, urceolate and densely pubescent dark purplish flowers, densely pubescent purplish filaments, and yellowish-white, ovoid berries snugly covered by 10-ribbed accrescent calyx. Molecular phylogenetic analysis, based on a combined matrix of four DNA markers (nrITS, trnL-F, waxy, LFY), revealed that T. pengiana is deeply nested within the subtribe Withaninae. It forms a sister relationship with Archiphysalis chamaesarachoides, although with weak support.
