本文報導了廣西壯族自治區石灰岩地區苦苣苔科報春苣苔屬(Primulina)兩新種:假密毛小花苣苔(P. pseudomollifolia)和多裂小花苣苔(P. multifida)。根據細胞核ITS 及葉綠體trnF-L 基因間與內插子DNA 序列,此兩新種植物確定屬於報春苣苔屬。假密毛小花苣苔與密毛小花苣苔(P. mollifolia)較相近,但不同在於葉基部楔形到闊楔形,花冠白色至粉紅色,12-14 毫米長,花冠筒筒狀,8-9 毫米長,花絲5-6 毫米長,退化雄蕊3 枚,花期7-9 月。多裂小花苣苔與文采苣苔(P. renifolia)相似,但不同在於葉邊緣羽狀半裂,苞片卵形至闊卵形,長3-4 毫米,寬1.5-2 毫米,花冠筒筒狀,5-7 毫米長,花絲3-5毫米長,退化雄蕊3 枚,柱頭舌狀,花期6-8 月。
Primulina pseudomollifolia W.B. Xu & Yan Liu and P. multifida B. Pan & K.F. Chung from karst caves in Guangxi Zhuangzu Autonomous Region, China are described and illustrated as two new species. Their generic placement in the recently recircumscribed Primulina is supported by phylogenetic analyses of DNA sequence nuclear ITS and chloroplast trnF-L intron spacer regions. Primulina pseudomollifolia is similar to P. mollifolia (D. Fang & W. T. Wang) J.M. Li & Y.Z. Wang in being densely pubescent on both blade surfaces, but differs in the base of its blades being cuneate to broadly cuneate, its 12-14 mm long white to pink corolla 8-9 mm long tubular corolla tube, 5-6 mm long filaments, 3 staminodes, and flowering from July to September. Primulina multifida resembles P. renifolia (D. Fang & D. H. Qin) J. M. Li & Y. Z. Wang, but differs in the blade margins being pinnatifid; its ovate to broadly ovate bracts, 3-4 × 1.5-2 mm, 5-7 mm long tubular corolla tube, 3-5 mm long filaments, 3 staminodes, linguiform stigma, and flowering from June to August.
