    Scleria verticillata Muhl. ex Willd.

  • Description

    Species Description - Leaf blades inversely W-shaped. Inflated epidermal cells at median adaxial groove remarkably tall, oblong-ovate or bulliform. Adaxial epidermis with tall cells on both sides of lateral costas. Cells of abaxial epidermis uniformly small. Mesophyll not distinctly differentiated into palisade and spongy portions, without large intercellular spaces. A number of tannin cells throughout mesophyll. Assimilatory cells and tannin cells radially oriented around vascular bundles. Vascular bundles in one row in abaxial mesophyll; only single bundle sheath noted in the material so far examined, the component cells not conspicuously lignified; large vascular bundles supported by an abaxial crescentiform girder and an adaxial fiber strand.

  • Discussion

    Note. The radially arranged assimilatory cells are not a common anatomical character in the tribe Sclerieae. This arrangement is manifestly shown by this species and Scletia mikawana.
