    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; oblong; 1 length of spikelet; membranous; 5 -veined; obtuse. Fertile lemma oblong; 3-4.5 mm long; indurate; dark brown; without keel. Lemma surface granulose. Lemma margins involute. Lemma apex acute. Palea involute; indurate; without keels.
