研究背景东南亚与热带非洲、马达加斯加、南印度和斯里兰卡以及东喜马拉雅地区是凤仙花属植物物种多样性的5个主要热点地区。中国也有丰富的凤仙花种类，特别是在石灰岩岩溶或丹霞地貌中。凤仙花属植物具有左右对称的花朵和不同的花冠形态和颜色，以其观赏用途而闻名，但它们在分类学上也是臭名昭著的。在浙江及邻近地区凤仙花属修订工作中，采自浙江省。结果基于核ITS、叶绿体atpB-rbcL和trnL-F序列的系统发育分析，以及花粉粒和种皮的显微形态，有力地支持了该新种与扁平萼凤仙花（Impatiens platysepala）的亲缘关系。Chloroxantha YL Chen.反过来，无论是分子数据和形态特征也足以区分其他两个countermeasurement.ConclusionsOur详细的形态观察和分子系统发育分析的新物种武夷凤仙作为一个新的物种科学的认可。
BackgroundSoutheast Asia, together with tropical Africa, Madagascar, South India and Sri Lanka, and the eastern Himalayas, are the five primary hotspots of species diversity of Impatiens (Balsaminaceae). China is also rich in Impatiens species, especially in the limestone karsts or ‘Danxia’landforms. With zygomorphic flowers and diverse corolla morphology and color, the species in Impatiens are well-known for their ornamental use, but they are also notorious in taxonomy. During the preparation of revision of Impatiens in Zhejiang and adjacent regions, an unknown species was collected from Mt. Wuyi in Fujian Province, Southeast China.ResultsPhylogenetic analyses based on nuclear ITS, chloroplast atpB-rbcL and trnL-F sequences, together with micromorphology of pollen grains and seed coats, strongly supported the close relationship of the new species with Impatiens platysepala YL Chen and I. chloroxantha YL Chen. In turn, both molecular data and morphological characters also were sufficient to distinguish the new species from the other two counterparts.ConclusionsOur detailed morphological observations and molecular phylogenetic analyses support the recognition of Impatiens wuyiensis as a species new to science.
