 including the lateral leaves; pinnae ovate or lanceolate, to 20 cm. long, 

 the rachises puberulous; ultimate branchlets hardly more than 2 mm. 

 broad. Leaves heteromorphous ; leaves of the stipe scattered; of the 

 lower plane acute, minutely denticulate on both sides, broadest at the 

 rounded upper base, straight at the lower base, the largest 2Va mm. 

 long and 1 mm. broad; of the upper plane obliquely ovate, aristate- 

 acuminate, slightly keeled, the inner side minutely denticulate, rounded 

 at the base, the outer side subentire, slightly decurrent at the base, the 

 largest leaves 2 1 ;* mm. long and IVa mm. broad, with the cusp J A as 

 long as the blade; leaves of the branched portion gradually approximate; 

 leaves of the main rachis the largest; of the lower plane very remote, 

 spreading, to 3Va mm. long and IVa mm. broad, obliquely lanceolate, 

 acute, the upper side minutely denticulate, pale-margined in the lower 

 3 A, rotundate-cuneate at the base, the lower side entire, rotundate-cuneate 

 at the base; of the upper plane obliquely ovate, to 2V mm. long and 

 IVa mm. broad, subcuspidate-long-acuminate, the cusp Vs as long as the 

 blade, the sides partly narrowly pellucid-margined, the inner side remotely 

 denticulate, rotundate-cuneate at the base, the outer side hardly den- 

 ticulate, cordate-auriculate at the base, the auricle rounded ; leaves of the 

 branchlets similar but smaller; of the lower plane approximate, to 1V 

 mm. long and '2 mm. broad, bluntish, narrowed at the base. Spikes 

 solitary, IVa mm. diam.; sporophylla subisomorphous, ovate, mucronate, 

 keeled, denticulate, the ventral ones the largest, to IVa mm. long; macro-
