Usually forked and the long branches therefore mostly with cataphyls 
on all joints, androgynous. Internodes long (2-5x70-150 mm.), some- 
times granular, nearly terete, somewhat enlarged below the nodes. Cata- 
phyls a basal pair, mostly followed by a second or occasionally a third 
pair at intervals of 5-10 mm., subannular. Leaves from broadly lance- 
olate to elliptical, ovate or orbieular, very obtuse or somewhat blunt- 
aeuminate, 5-8 or 10x10-16 em., usually abruptly wing-petioled for 10-20 
mm. Spikes often clustered, long (30-50 or 70 mm.), with mostly 4 or 5 
rather long joints thickened except at the ends, some 20-flowered in 44-2 
series: pedunele some 8 mm. long, with a basal pair of scales. Fruit 
white, round-ellipsoid, mostly smooth, 3x4 mm.: sepals inflexed or some- 
what parted.— Plates 202, 203. 
Upper West Indies and Northern South Ameriea; absent from the 
intervening Caribbees.— The type from Cayenne.
