    Note
    C.B. Clarke points out that C. parasitica Kunze (Suppl. Schkuhr’s Riedgräsern: 83 adnot. (1842)) is an earlier name but although he refers to Uncinia digyna Hochst., Herb. Abyss. II: 687 there is no word of description by Kunze nor on the Hochstetter label so it is a nom. nudum. See after next species for hybrids. A number of specimens are very short e.g. Hedberg 5021 (Mt Kenya, Nanyuki District, near Naramoro Lodge, 13 July 1971) and their status needs investigating.
