Forked at every node, sometimes with a terminal spike, the rather : 
long slender branches therefore with cataphyls on all joints, androgy- 
nous. Internodes rather long (1-3x30-80 mm.), the upper transiently 
more or less rhombieally compressed. Cataphyls a nearly basal pair fol- 
lowed at 10-20 mm. by a second, exceptionally a third pair interposed, 
not tubular, acute, white-margined. Leaves lanceolate, mucronately sub- 
acute, 2-3x6-9 or even 5x12 em., euneately subpetioled for scarcely 5 mm. 
Spikes mostly solitary, long (40-75 mm.), with about 4 slender joints 
some 18- to 40-flowered in 44-2 series: peduncle 2 mm. long, followed by 
a sterile joint: scales scarcely ciliate. Fruit white, round, nearly smooth, 
4 mm. in diameter: sepals inflexed.— Plates 237, 238, 239. 
Antillean region on Mangifera, Petitia, Trichilia, ete.—The type 
from Santo Domingo.
