摘要


本文報導了中國廣西苦苣苔科(Gesneriaceae)一個新種-陽朔報春苣苔(Primulinayangshuoensis Fang Wen & Y.G. Wei)。該種近緣於長毛報春苣苔(P. villosissima (W.T. Wang) Mich. Moller & A. Weber)與方氏報春苣苔(P. fangii (W.T. Wang) Mich. Moller & A.Weber),且易於與報春苣苔屬內其他種區分。陽朔報春苣苔具多數葉(12-14枚);葉片小型(3.5-6.5 × 2-4.5cm),具長葉柄(2-5cm),闊倒卵狀圓形、近圓形或圓形,且肉質化,葉兩面均具乳頭狀凸起基部的硬毛;它有較多的花序(8-10);每一花序上具較少的花(1-4);苞片披針形;花藥無毛;退化雄蕊2枚;其花期於10月後半期到11月。

並列摘要


A new species of Primulina, P. yangshuoensis Y.G. Wei & Fang Wen (Gesneriaceae) from NE Guangxi, China, is described and illustrated in this report. This new species is similar to P. villosissima (W.T. Wang) Mich. Möller & A. Weber and P. fangii (W.T. Wang) Mich. Möller & A. Weber,, and is easily distinguished from other species in Primulina by its morphology of leaves and flowers. P. yangshuoensis has more leaves (12-14) with long petioles (2-5 cm long), smaller carnosulus or carnosus leaf blades (3.5-6.5 × 2-4.5 cm), broadly ovate-round, subround or round in shape, broadly cuneate or sub-rotund base and densely papillose-hispid hairs on both surfaces, and it possesses more cymes (8-10), fewer flowers (1-4 per cyme), lanceolate bracts, glabrous anthers, and two staminodes per flower. It flowers from second half of October to November.
