背景-安娜是苦苣苔科的一个小属，产于中国和越南。方法：通过植物标本的分类学和形态学研究，花粉和种子的扫描电镜观察，以及分子系统发育分析，发现了一个新种，即红花安娜属（Anna rubidiflora），该属为一新种，命名为S. Z. He，F.Wen & Y. G. Wei。描述了中国南方（贵州省开阳县）的一种狭区分布种。它不同于形态相似的种A。Ophiorrhizoides（Hemsl.）Burtt & Davidson是一个较大的植株，茎不裂，全缘叶片边缘，背面带绿色的白色叶片具稍紫色的叶脉，倒卵状披针形的萼裂片具截形和近圆形先端没有叶脉，以及红紫色花冠。新描述的物种都说明了线条画和照片。还提供了一个位置和分布图。系统发育分析证实A. Rubidiflora是安娜的一个成员，也是A. Ophiorrhizoides。
Background - Anna is a small genus of Gesneriaceae, occurring in China and Vietnam. During fieldwork in Guizhou, China, a representative of this genus was discovered which did not match the description of any of the three known species.Methods - Herbarium taxonomical and morphological studies, SEM of pollen and seeds and molecular phylogenetic analyses were performed.Key results - A new species, Anna rubidiflora S.Z.He, F.Wen & Y.G.Wei, a stenochoric species from the southern part of China (Kaiyang county of Guizhou province), is described and illustrated. It differs from the morphologically similar species A. ophiorrhizoides (Hemsl.) Burtt & Davidson by being a larger plant with undivided stem, its entire leaf blade margins, its abaxial greenish-white leaf blades with slightly purple nerves, its obovate-lanceolate calyx lobes with truncate and nearly rounded apex without nerves, and its reddish-purple corolla. The newly described species is illustrated both by a line drawing and photographs. A locality and distribution map is also presented. A phylogenetic analysis confirmed that A. rubidiflora is a member of Anna and a close relative of A. ophiorrhizoides.
