at the base ; of the ultimate branchlets subdimorphous, crowded, decurrent, 

 to 2 mm. long, acutely acuminate, the ventral ones su bianceolate, sub- 

 erect, slightly incurved, minutely spinuloso-serrulate, the dorsal and lateral 

 ones subulate,, subspreading, strongly incurved, entire or sparingly denticul- 

 ate, thickened towards the base, somewhat longer than the ventral ones. 

 Spikes solitary and terminal on the branchlets, sessile, often cernuous, 

 cylindrical, + 3 — 10 mm. long, + 2 — 3 mm. diam. ; sporophylla acum- 

 inate from an ovate base, coriaceous, ecostate, eroso-ciliolate.

Main stem erect or more probably scandent, terete, pinnately branched, 

 sparsely leafed. Barren branches copiously dichotomous with leafy, mostly 

 more or less erected rachises and erected ultimate branchlets + 10—20 

 cm. long, flattened, I'/j — 1''/4 mm. broad at the base. Leaves hetero- 

 morphous; leaves of the main stem scattered irregularly, + '/a — ''4 ^^'^• 

 long, with a - small, coriaceous, peltate-oblong, keeled portion pale-brown 

 to castaneous when dry, and a flat, white-scariose, more or less deciduous 

 portion at the base and the apex, the basal portion short, more or less deeply 

 longitudinally fimbriate, the apical portion long-subulate, ciUolate-denticulate; 

 lower leaves of the branches similar to those of the main stem, following 

 ones passing gradually into those of the ultimate branchlets; leaves of 

 the branchlets platystichous ; lateral leaves opposite, in 2 close planes 

 (apparently 1 plane), isomorphous, imbricate, + '/a — ^U cm. long including 

 the long-decurrent-adnate portion brown when dry, the free portion with 

 a short, thick, convex basal part and a long, erect, subadpressed, 

 subulate, flat, deciduous or persistent, sparingly serrulate-ciliolate, 

 white-scariose apex, the decurrent portions contiguous, separated by 

 a narrow ventral groove, and a broad dorsal groove in which the 

 intermedial leaves are placed, the leaves of both (ventral and dorsal) 

 planes similar but alternate; intermedial leaves remote, in 2 close rows 

 (apparently 1 row), the decurrent portion narrowly cuneate, keel-shaped, 

 the base of the free portion flattened, the apex similar to that of the 

 lateral leaves. Fertile branches copiously divergent-dichotomous, roundish
