MEMOIRS OP THE NEW YORK BOTANICAL GARDEN 



[VOL. 11 



3-celled tip, the margins entire, the vitta only half as wide as the segment base, 

 ending well below the apex ; leaf-cells thick-walled, the trigones and pits rarely 

 distinct, the margins irregular, the cuticle verruculose; lamina ovate, the 

 margins often incised, toothed, or ciliate at the base, the vitta forked near 

 the base, continuing as two distinct ribs into the segments. Underleaves as large 

 as the leaves, the lamina less ovate, the segments conspicuously divergent. Plants 

 dioicous. Male inflorescence terminal but becoming intercalary on the stem, the 

 bracts and bracteoles as large as the leaves and underleaves, pouched ; antheridia 

 large, spherical, in pairs in the axils of the bracts and bracteoles. Female inflor- 

 escence terminal on the stem, with one subfloral innovation, the bracts and 

 bracteoles in four or five series, the innermost series largest, with a long lamina 

 with decurved marginal teeth and cilia, the segments divergent, linear. Perianth 

 (immature) 3-parted to near the middle, the divisions deeply bilobed, the seg- 

 ments narrow, linear. Sporophyte not seen. Fig. 3, a-e.

Plants large, light green to greenish-brown, in tufts or pendent ; stems 

 slender, to 30 cm long, often shorter, when dry mostly 1.5 mm wide, occasionally 

 branched, the branches lateral or ventral, leafy. Line of leaf insertion trans- 

 verse. Leaves more or less faleate-secund and the stem-tip curved when dry, or 

 irregularly spreading, sub rectangular, imbricate at the base, bifid to less than 

 one-half of the length ; segments shorter than the lamina, lanceolate, tapering 

 to the 1-2-celled tip, the margins entire, the vitta about one-fourth to one-half 

 the width of the base of the segment, ending below the apex ; lamina long, with 

 a few marginal teeth or cilia near the base, the vitta bifurcate just below the 

 sinus ; leaf-cells thick-walled, the trigones and thin-walled pits occasionally dis- 

 tinct, the cuticle verruculose. Plants dioicous. Female inflorescence terminal, 

 with one subfloral innovation, appearing lateral, the bracts and bracteoles in 

 four or five series, the innermost series with crenulate and toothed margins. 

 Perianth (immature) deeply 3-parted, each part deeply bifid, the segments 

 lanceolate, the margins dentate and crenulate as in the bracts. Male inflorescence 

 and sporophytes not seen. Fisr. 4. a-c.
