Shoots 14 — 20 cm. long, to 3-pinnate, erect from an ascending base, 

 the stem 2-sulcate down the face, convex on the back ; branches spreading, 

 elongated, acuminated, narrowed at the base; ultimate branchlets 2 — 3 'A 

 mm. broad including the lateral leaves. Leaves heteromorphous; lateral 

 leaves of the stem ovate, obtuse, entire, nearly equally cordate on both 

 sides at the base, the upper (inner) side ciliated in the lower half, the 

 lower (outer) side only so at the base; intermedial leaves of the stem 

 rhomboidal-ovate, acuminated, ciliated on both sides, auriculate-cordate 

 on the outer side and rounded on the inner side at the base; leaves of 

 the branches deep-green above, paler beneath; lateral leaves of the 

 branchlets rather approximate, with the interstices less broad than the 

 leaves, spreading, ovate, subfalcate, subobtuse, subentire, auriculate-cordate 

 and ciliated on the upper side at the base, rounded or rotundate-cuneate 

 on the lower side at the base; intermedial leaves of the branchlets 'A as 

 long, broadly ovate, subfalcate, acuminate, obliquely rounded at the 

 base, with both edges ciliated. Spikes to 5 mm. long; sporophylla not 

 very heteromorphous; of the upper plane ovate-elongate, acuminate, 

 ciliolate, keeled; of the lower plane somewhat smaller, broadly ovate, 

 acuminate, ciliate, slightly keeled ; microspores smooth ; macrospores

 thick, sparingly foliate, the upper part branched, lanceolate in outline; 

 lower pinnae 10 — 15 cm. long, 2-pinnate; ultimate branchlets 6 — 8 mm.
