 spreading, smaller, to about 2 mm. long, often more acute, the sub- 

 marginal spurious vein accompanied by 2 abbreviated or interrupted 

 intermedial ones, the upper surface provided with a few scattered, short, 

 spine-like hairs near the lower edge, the base obliquely rotundate-cuneate ; 

 intermedial leaves erect, roundish- or oblong-ovate, pellucid-margined, 

 long-cuspidate, the cusp as long as the blade ; of the main rachis abruptly 

 cuspidate, the inner edge ciliate, the outer edge ciliolate, the base semi-

 the branchlets acuminate-cuspidate or less abruptly cuspidate, sparingly 

 ciliolate or serrulate, obliquely rotundate or rotundate-cuneate at the base. 

 Spikes solitary or apparently 2-nate (i. e. solitary on very short branchlets), 

 square, 1 — 1 % mm. diam. ; sporophylla lanceolate-ovate, acuminate, ciUolate-

Shoots erect from a short-creeping base, about 35—40 cm. high, the 

 lower part simple, stipitiform, obtusely 4-angular, dirty-pale-fuscous, 2 — 272 

 mm. thick towards the base, the upper part closely pinnately decompound, 

 deltoid or ovate in outline; main rachis to 4—5 mm. broad including the 

 lateral leaves; pinnae more or less ascending, the lower ovate-lanceolate, 

 to about 17 "j cm. long, 8-pinnate in the lower part; pinnulae to about 

 272 cm. long, suberecto-patent ; tertiary branches erecto-patent, simple or 

 more generally forked or sparingly pinnate; ultimate branchlets suberect, 

 '/i— IVj cm. long, 174—2 (sometimes to 27,) mm. broad. Leaves of the

 copiously, minutely serrulate, ciliolate towards the base; leaves of the 

 branches and those of the upper part of the main rachis heteromorphous ; 

 lateral leaves subfalcate-ovate, more or less ascending ; of the main rachis
