    Note
    " Richards 14161b bears four determinations! Kobresia lehmannii (completely erroneous), S. lanceum, S. rufum det. Kukkonen in 1984 and S. ludwigi Hochst. det. Kukkonen in 1985. Gordon-Gray cites the Haines and Lye reference to S. rufum including their fig. 761 drawn from Robinson 3070 which was determined as S. rufum in 1984 and 1985. Kükenthal sinks S. ludwigii into S. rufum as also did Kukkonen in 1983.
