blunt to mucronulate, the upper edge minutely denticulate, the lower 

 edge entire; of the rachises 1 mm. long, obliquely 2-auriculate-cordate at 

 the base and moderately copiously ciliolate, produced at the lower (outer) 

 base; of the branchlets smaller, more spreading, cordate and rather 

 sparingly ciliolate at the lower base; intermedial leaves erect; of the 

 rachises ovate, 1 mm. long, subacute, the inner edge denticulate, the 

 outer edge entire, the base obliquely cordate and sparingly ciliolate, much 

 produced on the outer side; of the branchlets smaller, hardly ciliolate at 

 the base, the inner base rotundate-cuneate, the outer base cordate, less 

 produced. Spikes short, terminal, 1 mm. diam.; sporophylla ovate, acute, 

 keeled. - - Plants recently gathered, and very probably identical with 

 this, agree with the following description : Shoots erect from an ascending 

 base, 30 60 cm. long, the lower part simple, terete, stramineous, IV* 2 

 mm. thick, the upper part copiously 4 5-pinnate, lanceolate-ovate in 

 outline, to 40 cm. long and 20 cm. broad, the rachises very sparingly 

 hairy; pinnae erecto- patent, lanceolate, to 20 cm. long; ultimate branchlets 

 1 r/2 mm. broad. Leaves of the stipe erect, adpressed, the lower remote, 

 ovate, bluntish or acute, entire or partly very minutely denticulate, 

 broadly adnate, subpeltate, not produced at the base, the higher similar 

 to those of the main rachis ; leaves of the main rachis- isomorphous, erect, 

 remote, obliquely ovate, acute, the inner side minutely serrulate, ciliolate- 

 serrulate at the rounded base, the outer side minutely serrulate, auriculate- 

 cordate at the base, the auricle produced, slightly incurved, minutely and 

 irregularly eroso-ciliolate, the largest leaves 2Y mm. long, IVa mm. broad; 

 leaves of the branches growing gradually smaller, heteromorphous; lateral 

 leaves involute when dry; of the secondary rachises suberect, nearly as 

 broad as long, bluntish or mucronulate, obliquely 2-auriculate-cordate and 

 irregularly eroso-ciliolate at the base, the upper side minutely denticulate, 

 the lower side entire; of the ultimate branchlets subspreading, close or 

 imbricate, ovate-oblong, blunt, spuriously veined, the upper side sparingly 

 minutely denticulate, rounded at the base, the lower side entire, or 

 sparingly ciliolate-denticulate at the truncate-rotundate or subcordate base, 

 the largest leaves 3 A mm. long and V mm. broad; intermedial leaves 

 erect; of the secondary rachises subfalcate-ovate, acute or shortly acuminate, 

 the inner side minutely serrulate, rounded and sparingly ciliolate at the 

 base, the outer side subentire or obsoletely denticulate, much produced 

 and eroso-ciliolate at the auriculate-cordate base; of the ultimate branchlets 

 close, subfalcate-ovate, acute or shortly acuminate, the inner side provided
