重庆荨麻科一新种——缙云赤车

在重庆市北碚区缙云山野外植物调查过程中,于海拔500~800 m的溪边阴湿沟谷中发现一种荨麻科植物,虽然该物种雌花序具花序托,但因其雌花花被片5枚,外面先端具角状突起,瘦果只具瘤状突起,更符合赤车属的特征,且结合分子系统学证据,该物种明显属于赤车属。该物种的特征在于其具花序托和总苞的雌花序,根据这一特征可将其置于头序赤车组(Sect.Elatostematopsis W.T.Wang),与头序赤车(Pellionia cephaloidea W.T.Wang)相似,但与后者区别在于其为草本,叶为羽状脉,侧脉在狭侧2~3条,宽侧3~4条,外层苞片2枚,无毛,背面具1绿色龙骨状突起,内层苞片8~12枚,无毛,背面具1绿色龙骨状突起,雌花花被片背面顶端具角状突起,瘦果椭圆形,具瘤状突起。基于形态学和分子系统学证据,特将它描述为赤车属一新种,命名为缙云赤车(Pellionia jinyunensis C.Xiong,F.Chen&H.P.Deng)。
