| 摘要: |
| 报道了广西石灰岩地区苦苣苔科报春苣苔属(Primulina Hance)1新种——北流报春苣苔(P. beiliuensis B. Pan & S. X. Huang)。该新种在形态上与黄花牛耳朵[P. lutea(Yan Liu & Y. G. Wei)Mich. Möller & A. Weber]较近,但叶宽卵形,叶基部近心形,叶缘具浅钝齿或呈浅波状齿,花冠紫色,花冠、花序梗、花梗、苞片及花萼均被紫色短柔毛而区别与后者; 分子生物学证据表明,在系统发育上与桂林小花苣苔[P. repanda var. guilinensis(W. T. Wang)Mich. Möller & A. Weber]近缘,但两者在形态学上相差较远。 |

| Abstract: |
| A new species of Gesneriaceae,Primulina beiliuensis B. Pan & S. X. Huang from limestone areas in Guangxi, China,is described and illustrated here. The new species is morphologically similar to P. lutea(Yan Liu & Y. G. Wei)Mich. Möller & A. Weber,but easily differs from the latter in its leaf blades broadly ovate,base nearly cordate, margin shallowly obtuse-dentate or shallowly undulate-serrate, corolla purple, corolla, peduncle,bracts and calyx lobes outsides,and pedicel with purple pubescence. Molecular evidences hint that it is systematically similar to P. repanda var. guilinensis(W. T. Wang)Mich. Möller & A. Weber,but the morphologies of two relatives are obviously different. |
