Hickelia A. Camus
Excluding Pseudocoix
Habit, vegetative morphology. Perennial. The flowering culms leafy. Culms woody and persistent (slender); scandent; branched above. Leaves not basally aggregated; without auricular setae. Leaf blades lanceolate (acuminate); broad; to 1015 mm wide (to 10 cm long); rounded at the base; pseudopetiolate; disarticulating from the sheaths (presumably); ligule present; small.
Reproductive organization. Plants bisexual, with bisexual spikelets; with hermaphrodite florets.
Inflorescence. Inflorescence indeterminate; without pseudospikelets; with stellate spikelet clusters around the nodes. Spikelet-bearing axes capitate; clustered (the dense capitula aggregated); persistent.
Female-fertile spikelets. Spikelets 1018 mm long; becoming ventricose; disarticulating above the glumes (the glumes persistent). Rachilla prolonged beyond the uppermost female-fertile floret.
Glumes several (35); relatively large; hairy (long-pilose); pointed; awnless; very dissimilar (the lower short and membranous, the two upper crustaceous and like the lemma). Spikelets with incomplete florets. The incomplete florets proximal to the female-fertile florets. Spikelets with proximal incomplete florets. The proximal incomplete florets 2. The proximal lemmas awnless; more or less equalling the female-fertile lemmas to decidedly exceeding the female-fertile lemmas; similar in texture to the female-fertile lemmas; becoming indurated (shining, ventricose).
Female-fertile florets 1. Lemmas broad, convolute, ovate; decidedly firmer than the glumes; becoming indurated (and inflated); entire; awnless; non-carinate; many-nerved. Palea present; relatively long; palea apically pilose; indurated (shining); several nerved (1620 nerves); keel-less. Lodicules present (acute, small). Stamens 6. Ovary hairy; with a conspicuous apical appendage. The appendage broadly conical, fleshy. Stigmas 3.
Fruit, embryo and seedling. Fruit medium sized (9 mm long); longitudinally grooved. Pericarp thin (becoming dilated at the base of the style).
