凤仙花属(Impatiens)植物主要分布于旧世界的热带和亚热带山区, 对生长环境要求极度严苛, 深入分析其地理分布格局与特征, 可为种质资源调查和利用提供理论依据。本研究通过系统检索文献资料, 更新了该属植物物种名录, 整合其地理分布、海拔、特有性等信息, 建立了中国野生凤仙花属植物地理分布数据库。截至2022年3月, 中国共记载野生凤仙花属植物352种(包含18变种1亚种1变型), 其中中国特有种273种。除上海市外, 中国其他各省级行政区均有野生凤仙花属植物分布, 其中云南省分布有165种, 其次为四川省(119种)和西藏自治区(69种)。县级尺度上, 贡山独龙族怒族自治县和腾冲市以51种并列物种丰富度第一, 其次是福贡县(42种)。中国野生凤仙花属的分布总体呈现以热带、亚热带为中心向高纬度和高海拔区域扩散的格局, 广义横断山区、西藏南部地区、滇黔桂喀斯特区域、长江中下游等地为凤仙花属植物集中分布的热点地区。     

Impatiens maculifera sp. nov. (Balsaminaceae) Yunnan,China

Impatiens (Balsaminaceae) is a notoriously difficult genus to study for reasons that include small, remote and endemic areas of occurrence, and difficulty in obtaining well‐dried herbarium specimens and separating and reconstructing floral parts from available dried specimens. Impatiens has also been notoriously difficult when it comes to phylogenetic resolution at the infrageneric level, but a new system with two subgenera (Impatiens and Clavicarpa) was recently proposed by Yu et al. and it has made it easier to classify newly discovered species. Impatiens maculifera, a new species of Balsaminaceae from Malipo County, Yunnan, China described here, is similar to I. parvisepala S.X. Yu & Y.T. Hou in having racemose inflorescences, four lateral sepals, clavate capsules and ellipsoid seeds, but differs in having leaves narrowly oval or with elliptic–lanceolate blades (versus obovate or obovate–lanceolate), obvious petioles (versus leaves subsessile), racemose inflorescence with 8–12 flowers (versus 6–8 flowers), flowers greenish yellow (versus yellow), lateral united petals and lower sepal with dense red spots (versus red spots absent), and dorsal petal with apparent stalk at base (versus unapparent stalk). Morphological characters and molecular phylogenetic analyses of DNA sequences from both nuclear ribosomal and plastid genes show that the new species differs distinctively from I. parvisepala. Furthermore, I. maculifera is distinguished from other Impatiens species based on morphological, micromorphological and palynological evidence, and molecular data.     

Impatiens macrantha (Balsaminaceae) sp. nov., a new species from limestone areas in Guangxi,China

Impatiens macrantha S. X. Yu&Ying Qin (Balsaminaceae), a new species from Guangxi, China, is described and illustrated. Phylogenetic analysis based on molecular data shows the new species to belong to I. subg. Clavicarpa and to be closely related to I. tubulosa with which it shares succulent stems and racemose inflorescences, but it can be easily distinguished by having a 4 – or 5 – ridged stem, obovate or elliptic leaf blade, and saccate lower sepal. Furthermore, I. macrantha is distinguishable from other Impatiens in China by its obviously larger leaves and flowers. The evidence from morphology and molecular data both support I. macrantha as new to science.     

Hedychium menghaiense (Zingiberaceae), a new species from Yunnan,China

Abstract Hedychium menghaiense X. Hu & N. Liu, a new species of the Zingiberaceae from Yunnan Province, China, is described and illustrated. The new species is currently known only from its type locality, Nannuoshan Mountain, Menghai County, growing under evergreen broad‐leaved forests at altitudes of 1400–1700 m. It is similar to Hedychium forrestii Diels, but differs in its narrower and emarginate labellum folded inwards lengthwise, narrower staminodes, and scarlet stamen. The recognition of the new species is supported by the results from analysis of sequence‐related amplified polymorphism markers.
