Abstract

The semi-double (semiplenus) floral trait is highly valued in the field of horticulture, yet it remains exceptionally rare in wild plants. Rubussemiplenus, a new species with naturally occurring semi-double flowers, is described and illustrated. This new species was discovered in the Nanyue Hengshan National Nature Reserve, Hunan Province, China. It is distinguished by its herbaceous to dwarf subshrub habit, simple suborbicular leaves (0.7-2.5 × 0.7-2.5 cm), and semi-double flowers with dicyclic petals (10-12). Molecular phylogenetic analyses based on ITS and rbcL + matK sequences consistently confirmed that R.semiplenus belongs to Sect. Rosaefolii as defined by Focke and is closed to R.hirsutus.

Rubussemiplenus(蔷薇科),一新种,开半重瓣花,产于中国湖南。
半重瓣花性状在园艺领域具有很高的价值,但在野生植物中却极为罕见。本文描述了半重瓣花的一新种半重瓣花。本新种发现于中国湖南省南岳横山国家级自然保护区。其特点是草本到矮灌木习性,单叶近圆形(0.7-2.5 × 0.7-2.5 cm),花半重瓣,花瓣双环(10-12)。基于ITS和rbcL + matK序列的分子系统发育分析一致地证实了r.t semiplenus属于Focke定义的Rosaefolii节,与r.t hirsutus接近。
