the lower plane remote on the main rachis, contiguous on the branchlets; 

 of the main rachis more or less spreading, oblong, 3 mm. long, Vj as 

 broad, blunt or bluntish, entire or subentire towards the apex, minutely 

 denticulate on the upper side in the lower part, obliquely rotundate to 

 cuneate at the base; of the secondary rachises similar but more falcate, 

 somewhat narrower, more or less indistinctly spuriously veined, more 

 narrowed at the base ; of the branchlets similar, more ascending, smaller, 

 to 2 mm. long; leaves of the upper plane erect, shortly cuspidate, 

 somewhat keeled ; of the main rachis subremote, broadly oblong, to 2 mm. 

 long, very minutely denticulate, obliquely rotundate-cordate at the base; 

 of the branchlets similar, smaller, oblong, entire or nearly so, the outer 

 base cordate and somewhat produced, the inner base rotundate-cuneate. 

 Spikes solitary, square, to 2 cm. long, 1 V2 mm. diam. ; sporophylla erecto- 

 patent, ovate, acuminate, minutely denticulate, keeled, the largest Vk mm. 



long; macrospores ? microspores yellowish, provided with tuber- 



culiform, subconical, capitate or stipitate-capitate projections on the basal 

 side. — Largest secondary shoots of the dichotomous forms whether or 

 not flagellate at the apex of both sterile and fertile ultimate branchlets 

 and growing out to now shoots.

Shoots decumbent, 20 cm. more or less long, pinnately compound, 

 whether or not forked at the base, the stem 5 — 6 mm. broad including 

 the lateral leaves, the ultimate branchlets 2V2 — 3 mm. broad. Leaves 

 heteromorphous ; lateral leaves somewhat remote on the stem, contiguous 

 on the branchlets ; of the stem varying from spreading to slightly deflexed, 

 unequal-sided, lanceolate-oblong, 2% — 3 mm. long, 1 mm. broad, bluntish, 

 the upper side entire or subentire towards the apex, denticulate in the 

 lower part, whether or not ciliolate at the broadly rounded or subcordate 

 base, the lower side entire, or minutely and sparingly denticulate at the 

 narrowly rounded base ; of the branchlets similar but smaller, the largest 

 r/2— 1'/4 mm. long, more ascending, less unequal-sided, rather narrowly 

 rotundate-cuneate at the base; intermedial leaves erect; of the stem 

 remote, oblong, 2V« — 3 mm. long, cuspidate, denticulate, obliquely cordate 

 at the base or the inner base rotundate to rotundate-cuneate, the outer 

 base produced, the cusp as long as the blade or somewhat longer; of the 

 branchlets similar but smaller, imbricate, more narrowly rotundate-cuneate
