IV4 mm. long; of the branchlets much smaller, somewhat keeled. Spikes 

 3—6 mm. long, 1 mm. broad, nearly square; sporophylla deltoid-ovate, 

 acute, very narrowly poUucid-margined, loosely minutely denticulate; of 

 the upper plane strongly keeled, to 1 mm. long, proportionally longer 

 and narrower than those of the lower plane, which are slightly keeled; 

 macrospores yellowish or ochraceous, finely and densely verruculose on

(133) S. inlerfcxta, Spring, Mon., II, 237; Bk., Fern All., 107, 

 Shoots decumbent, repeatedly dichotomous, caespitose, the secondary 

 shoots 2—5 cm. long, sparingly pinnate, the apex not rarely tlagellate- 

 elongate and very minutely foliate in the longest forms, the main stem 

 Va mm. thick, pale-stramineous, 2 'A mm. broad including the lateral 

 leaves; pinnae short, to 1 cm. long, simple, or the lower more elongate 

 and sparingly pinnate; ultimate branchlets PA — 2'/4 mm. broad. Leaves 

 heteromorphous, membranaceous; leaves of the lower plane ascending, 

 rather equal-sided; of the stem distinctly, though not very, remote, ovate, 

 IV4 — 2 mm. long, 1 mm. broad, straight or slightly falcate, very minutely 

 apiculate-acuminate, rounded at the base, very minutely (nearly obsoletely) 

 denticulate on both sides, the upper side ciliate in the lower half; of the 

 branchlets similar, less remote, or subcontiguous, more rotundate-cuneate 

 at the base, 1 — Vli mm. long and 'A as broad; leaves of the upper plane 

 erect, broadly subfalcate-ovate, acuminate, subentire, or sparingly piloso- 

 denticulate on the outer side towards the base, the inner base rotundate- 

 cuneate, the outer base cordate or rotundate-subcordate ; of the stem 

 r/2 mm. long, somewhat remote; of the branchlets shorter, somewhat 

 imbricate. Spikes solitary, short, IV2 — 2 mm. broad; sporophylla of the 

 upper plane subfalcate-lanceolate, acute or somewhat acuminate, sparingly 

 or obsoletely denticulate, to I'A mm. long, the lower subspreading; of the 

 lower plane erecto-patent, ovate, acuminate, sparingly piloso-denticulate, 

 the lower ciliate and slightly keeled; macrospores whitish, broadly areolate 

 with a few reticulate, slender rumples, the apical ribs encircled by a 

 ring-shaped rumple; microspores yellow or pale-orange, the smaller smooth, 

 the larger moderately densely verruculose. — Cuming's No. 2015 is 

 unknown to mo, the description is taken from specimens gathered by
