摘　　要：该研究描述了产于福建省邵武市的苦苣苔科(Gesneriaceae)报春苣苔属(Primulina)一新种——邵武报春苣苔(P.shaowuensis X.X.Su,Liang Ma&S.P.Chen)。形态学观察结果表明,邵武报春苣苔与休宁报春苣苔(P.xiuningensis)最相近,二者的主要区别为:邵武报春苣苔的花筒近钟形,在中部膨大;花冠乳白色;退化雄蕊3,顶端稍显头状。经核糖体ITS和两个质体标记(atpB-rbcL和rpL32-trnL)进行系统发育分析结果表明,邵武报春苣苔在系统发育树上具有独立的位置,支持邵武报春苣苔为苦苣苔科植物一新种,且休宁报春苣苔和大齿报春苣苔(P.juliae)为其姐妹类群。This paper describes a new species of Primulina(Gesneriaceae)——P.shaowuensis,from Shaowu County in Fujian Province.Morphological analyses indicated that P.shaowuensis is most similar to P.xiuningensis.The main differences of them are P.shaowuensis flower tube subcampanulate and inflated in the middle;the corolla is milky white;staminodes 3,apex is slightly capitate.The result of phylogenetic analysis used nuclear ribosomal ITS and two plastid markers(atpB-rbcL and rpL32-trnL)indicated that P.shaowuensis has an independent position on the phylogenetic tree,which supports P.shaowuensis as a new species of Gesneraceae,and P.xiuningensis and P.juliae are its sister group.
