Scarcely forked, the rather long branches with basal cataphyls only, 

 androgynous. Internodes moderate (2-5x30-100 mm.), nearly smooth, 

 from somewhat rhombic becoming 2-keeled and terete, more or less swol- 

 len at the nodes. Cataphyls a nearly basal pair, followed by 2-4 other 

 pairs at intervals increasing to 20 mm., subannular-bifid. Leaves round- 

 elliptical, 5-7x8 cm., or elliptical-obovate and scarcely 2.5x5 cm., very 

 obtuse, cuneately or abruptly petioled for some 10 mm. Spikes more or 

 less clustered, rather long (40-50 mm.), with about half a dozen ellip- 

 soidal joints some 14-flowered in 4-(-2 series : peduncle 5 mm. long, some- 

 times with several pairs of sheathing scales. Fruit (immature, said to 

 be whitish) subglobose, fleshy- wrinkled, 3 mm. in diameter: sepals dull 

 red, closely inflexed. Plate 209.
