simple or forked; ultimate branchlets to 5 mm. long, 2 3 mm. broad 

 including the lateral leaves. Leaves heteromorphous ; leaves of the lower 

 plane subspreading or more or less ascending, more or less involute in 

 drought, somewhat remote on the stem, imbricated on the branchlets; 

 of the stem short-oblong, 1 3 A 2 mm. long, nearly as broad near the base, 

 blunt at the apex, rounded or somewhat cordate at the base, nearly 

 equal-sided, with the upper edge obsoletely denticulate towards the apex, 

 ciliolate in the lower part, the lower edge obsoletely denticulate towards 

 the apex, ciliolate at the base; of the branchlets similar but smaller and 

 relatively narrower; leaves of the upper plane erect, adpressed; of the 

 stem remote, oblong or subovate, 2 mm. long, shortly apiculate-acuminate, 

 very obliquely (nearly longitudinally) attached at the base, both sides 

 very narrowly pellucid-margined, minutely piloso-denticulate, the inner 

 base rotundate-cuneate, the outer base produced, cordate, ciliolate ; of the 

 branchlets similar, smaller. Spikes erect, square, terminal or lateral, 

 single or double, 3 6 mm. long, 1 mm. diam. ; sporophylla ascending, 

 isomorphous, cordate-oblong, to 2 mm. long, acute, subacuminate, the 

 lower more laxly disposed, irregularly and sparingly striolated with 

 longitudinal rows of dark-green cells, both edges minutely piloso-denticulate ; 

 macrospores ivory-white, smooth; microspores pale or orange, provided 

 with scattered, nearly regularly placed, obtusely conical or shortly cylin- 

 drical projections which are sometimes more or less thickened at the 

 apex. The description is taken from a cultivated specimen determined 

 by Hieronymus.

Shoots creeping, the loose branching between dichotomous and pinnate ; 

 main rachis 5 mm. broad including the lateral leaves; ultimate branchlets 

 2 3 mm. broad. Leaves heteromorphous; lateral leaves somewhat obliquely 

 ovate, spreading, shortly acuminate, the upper side minutely denticulate 

 towards the apex, gradually shortly ciliate towards the rounded base, 

 the lower side minutely denticulate towards the apex, sparingly ciliolate 

 at the subtruncate-cuneate base, the leaves of the main rachis the largest, 

 somewhat remote, 2\a mm. long by 1Y mm. broad, those of the branchlets 

 close, to IVz mm. long; intermedial leaves obliquely ovate, long-aristate- 

 acuminate, minutely denticulate on both sides, the outer base rounded, 

 the inner base rotundate-cuneate, the largest leaves 1V mm. long, the
