Spikelets small, 2-nate, one sessile, the other pedicelled, similar in shape or 

 the pedicelled reduced and smaller, the latter always different in sex except 

 sometimes the lowermost pair which may be homogamous (male or neuter), on 

 the fragile rhachis of many-jointed shortly peduncled racemes' ; joints and 

 pedicels filiform, longitudinally grooved and hyaline in the groove, disarticu- 

 lating horizontally; sessile and pedicelled (always ?) spikelets deciduous,. 

 the former with the adjacent joint and pedicel. Florets 2 in the sessile 

 spikelets, lower reduced to an empty glume, upper hermaphrodite, 2 or 1 in 

 the pedicelled spikelet, the lower male or neuter, the upper neuter or usually 

 quite suppressed. Sessile spikelet dorsally compressed, awned ; callus small, 

 shortly bearded. Involucral glumes equal, thinly chartaceous to membranous r 

 lower 2-keeled, with narrow sharply inflexed margins ; upper boat-shaped, 

 3-nerved, acutely keeled, Lower floral glume hyaline, nerveless, upper a 

 hyaline linear stipe, firmer upwards, passing into a slender awn. Pales or 

 very minute. Lodicules 2, minute, glabrous. Stamens 3. Stigmas exserted 

 laterally usually low down, longer than the styles. Grain oblong, obtuse, 

 dorsally slightly compressed ; embryo about half the length of the grain. 

 Pedicelled spikelet awnless, glumes, if present, hyaline, nerveless. 



Species probably over 25, mostly in Tropical Asia. 



Cke. (ii, 977-981) mentions 8 species which belong to the section 

 Amphilophis of Andropogon : Andropogon ccmpressus, Hook, f., A. Wood- 

 rowii, Hook. f., A. pertusus, Will-d., A. Kuntzeanus, Hack., A. ensiformis, 

 Hook, f., A. concanensis , Hook.f., A. intermedins, Cooke (non R. Br.), 

 A. odoratus, Dna. Lisboa. All these are now being transferred to the new 

 genus Amphilophis, Nash,
