 some 40- to 60-flowered in 6 series: peduncle 10-15 mm. long, the lower 

 scales forming large funnel-shaped tubes. Fruit (very immature) ap-

 name only. 



More or less pseudodichotomous, the rather long branches with cata- 

 phyls on all joints, androgynous?. Internodes moderate (2-3x60-80 mm.), 

 granular, subterete. Cataphyls usually a nearly basal pair followed by a 

 second pair some 25 mm. higher on the lowest joint, solitary and 15-20 

 mm. above the base on the others, deltoid, keeled and pointed. Leaves 

 lanceolate to elliptical, mucronately obtuse to long-acuminate, 3-6.5x6-9 

 or 10 cm., wing-petioled for some 5-10 mm., 5-nerved, drying thin and 

 orange. Spikes mostly solitary, long (50 mm. or more), with some 4 

 oblong joints about 40-flowered in 6 series : peduncle about 5 mm. long. 

 Fruit yellow, round, nearly smooth, 3 mm. in diameter: sepals closely

More or less pseudodichotomous, the rather long branches with cata- 

 phyls on all joints, drying yellow, androgynous?. Internodes moderate 

 (2-5x40-80 mm.), minutely cellular-papillate, the upper ancipital or 2-
