The sepals of this plant in Sikkim are grcen, as is the bract; and the petals and
lip arc of u greenish-yellow. The species is a very common and variable one. In the
north-west Himalaya the leaves are occasionally almost orbicular; the lip varies in
widtli from linear to hinceolato but its edges are always reflexed. A small form is
common in Sikkim.
