3*. V. delilis, Kuhn ; rhizome creeping ; scales linear, pale-brown ; fr. sessile, 

 tufted, ligulate, curved, blunt, narrowed at base, 1^-2 in. 1., 1 lin. br. ; texture 

 rigidly subcoriaceous ; midrib distinct from the base to the tip ; veins distant, 

 simple, oblique, very short and obscure ; sorus in a furrow near the midrib on

3*. V. sulcata, Kuhn ; rhizome short-creeping ; scales dense, lanceolate, pale- 

 brown ; fr. crowded, ligulate, obtuse, sessile, narrowed to the base, 2-4-in. 1., 

 in. br. ; sorus in an intramarginal deep furrow confined to the very much thick- 

 ened upper half of the frond where the midrib and veins are quite lost ; midrib 

 visible in the barren lower half ; veins forked ; margin beyond the sorus as thick 

 as the central portion of the lamina. Linn. 86. p. 68. 



Hab. Ceylon, Thwaites, 3807, and Society Islands. 



5*. V. Orbignyana, Mett., Kuhn, Linn. 3G. p. 67, Bolivia, differs from stipitata 

 by its narrower frond and broader gradually narrowed scales, obtusely densety 

 toothed, and formed of several rows of cells ; and V. gracilis, Moritz, Kuhn, 

 Linn. 36. 67, Columbia, is like Karsteniana, but with ovate scales, a short winged 

 stem, more ascending veins, and sorus nearer the margin.
