江西蓼属一新变种及其表皮形态特征

A New Variety of Polygonum from Jiangxi and Its Morphological Characters of Leaf Epidermis

    摘要
  • 摘要: 描述了产自江西庐山的蓼科(Polygonaceae)蓼属(Polygonum)一新变种--毛叶支柱蓼(Polygonum suffultum Maxim.var.tomentosum B.Li.et S.F.Chen var.nov.)。这一新变种与原变种支柱蓼(Polygonum suffultum Maxim.)的区别在于叶片背面密被白色绒毛,下表皮细胞垂周壁浅波状,气孔器类型不等型,气孔长20.15～27.55μm,宽17.45～22.47μm,气孔密度128.91个/mm2。

     

    Abstract: Polygonum suffultum Maxim.var.tomentosum B.Li.et S.F.Chen,a new variety of the Polygonaceae from Mt.Lushan,Jiangxi,China,is described.This variety is different from the typical one by hair-covering on lower epidermal,sinuolate anticlinal wall of lower leaf epidermal cells and anisocytic type stomas.The stomas are 20.15-27.55 μm long,17.45-22.47 μm wide,and 128.91 Num./mm2 dense.
