    Florets
    Basal sterile florets male, or barren (1); with palea. Lemma of lower sterile floret lanceolate (1), or elliptic (6); membranous; 5-6 -veined (1/6), or 7 -veined (4/6), or 8-9 -veined (2/6), or 11-13 -veined (1/6); obtuse (1), or acute (3), or acuminate (2), or attenuate (1); muticous (6), or awned (1). Fertile florets bisexual (5), or female (2). Fertile lemma lanceolate (1), or elliptic (3), or oblong (3); membranous (1), or chartaceous (1), or cartilaginous (5); without keel; 5 -veined (3/3).
