sharply ancipital. Cataphyls 1 or 2 basal pairs, usually with another 

 pair some 5 mm. higher, tubular-bifid, white-margined. Leaves falcately 

 lanceolate, obtuse, 1.5-3x7-10 cm., distinctly about 5-nerved, cuneately 

 attenuate for 5-10 mm. or more. Spikes mostly solitary, long (30-50 

 mm.), with about 3 rather slender joints turbinately some 30- to 50- 

 flowered in 4+2 series : peduncle 5-8 mm. long : scales not ciliate. Fruit 

 (immature) subglobose, microscopically cellular-papillate, 4 mm. in 

 diameter : sepals inflexed. Plate 184.

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

 5-7.5 cm., very obtuse, slenderly long-attenuate rather than petioled.
