Poaceae Group 9

See list of 10 genera in this group
  • 1a. Spikelets not organized into pairs or triplets, all pedicellate in an open panicle; disarticulation above the glumes, the falling floret leaving the glumes behind
  • 1b. Spikelets organized into pairs or triplets, some sessile (all pedicellate in Miscanthus, but that genus with glumes subtended by a ring of long, silky hairs); disarticulation below the glumes or between the rame segments, in either case the spikelets falling intact
    • 2a. Spikelets unisexual, with the carpellate inflorescences or carpellate portion of inflorescence borne below the staminate ones or staminate portions [Fig. 280]
    • 2b. At least the lower spikelet of each pair or triplet bisexual
      • 3a. Reproductive stems decumbent, creeping over the ground or other low vegetation; spikelets solitary at each node, the pediceled spikelet absent, represented only a pedicel up to 3 (–4) mm long
      • 3b. Reproductive stems ascending to erect, not creeping; spikelets solitary, paired, or 
in trios at each node, when solitary, with a pedicel usually longer than 3 mm
        • 4a. Spikelets in homogamous and homomorphic pairs (i.e., both spikelets of a pair 
of similar sex and similar morphology, respectively) [Fig. 240]
          • 5a. Spikelets in sessile-pedicellate pairs (i.e., one spikelet of a pair sessile, the other borne on a short pedicel) [Fig. 240]; terminal inflorescence of (1–) 2–4 (–6) branches originating from the summit of the peduncle, without or with a very short rachis less than 4 cm long
          • 5b. Spikelets in unequal-pedicellate pairs (i.e., both spikelets of a pair pedicellate, but 1 spikelet on a shorter pedicel than the other); terminal inflorescence usually with more than 15 branches distributed along a rachis 4–15 cm long
        • 4b. Spikelets in heterogamous and heteromorphic pairs or trios (i.e., spikelets of a pair or trio not of similar sex nor of similar morphology, respectively)
