| 摘 要： | 报道了中国四川报春花属(Primula L.)一新种——小繸瓣报春(P.hydrocotylifolia G.Hao,C.M.Hu&Y.Xu)。小繸瓣报春植株无毛、无粉,叶片多少呈圆形,具纤细的叶柄,开花期叶丛基部无鳞片,球形蒴果藏于宿存花萼,成熟时裂成不规则碎片,显然属于脆蒴报春组(sect.Petiolares Pax)革叶报春亚组(subsect.Chartacea W.W.Sm.&Forrest),并与该亚组的川西繸瓣报春(P.veitchiana Petitm.)最为接近,但后者植物体的各部分均远大于此新种,花序多花,花亦较大,二者之间无过渡类型。

| Abstract: | A new species of Primula is described and illustrated under the name of P. hydrocotylifolia G. Hao, C. M. Hu & Y. Xu. From general morphology it is clearly allied to the species of section Petiolares subsection Chartacea, which is characterized by the plants being glabrous and efarinose, lacking bud-scales at flowering time, the globose capsule including in the persistent calyx, not opening by valves but crumbling at the membrane apex, and by the leaves with more or less rounded blades and slender petioles. The new species superficially resembles P. veitchiana, but the latter can be easily distinguished by its much taller stature, many-flowered inflorescence and larger flowers. |
