in outline, with the leaves similar or subsimilar to those of the barren 

 branches but not quite similarly arranged on the ultimate branchlets 

 (=: the stalks of the spikes) which are ± I'/i — 6 cm. long. Spikes 

 terminal and solitary on the branchlets, deflesed, cylindrycal, ± 1— 2'/2 

 cm. long, + 5 mm. diam. ; sporophylla spreading, with a short, roundish- 

 oblong, coriaceous base with a flmbriate-ciliate, scariose margin and a 

 long, white-scariose, flmbriate-ciliate-serrulate, subulate apex. 



It seems that the stalks of the spikes and perhaps also other parts 

 of the plant are capable to curl and catch as tendrils of a vine when 

 meeting with other objects. — Te ventral and dorsal leaves of the lateral 

 rows are only distinguishable from each other by the position (ventral 

 or dorsal) of their apices.

Main stem (rhizome) wide-trailing, usually hypogeous, distichously 

 branched, with leaves only rudimentary; branches erect, the lower cop- 

 iously subflabellately branched ; branchlets subquadrangular, about 2 mm. 

 diam. including the leaves. Leaves 4-farious, erect, adpressed, imbricate, 

 subisomorphous, the dorsal ones a little smaller than the ventral, sub- 

 ulate-oblong, to 3 mm. long, thick, acute, entire, rounded or keeled on 

 the back, broadly adnate to and decurrent upon the stem or rachis. 

 Spikes solitary and terminal on the branchlets, sessile, cylindrical, 1 ' 4 — 2'/2 

 cm. long; sporophylla ascending, broadly ovate, acute or acuminate, 

 denticulate.
