 Ferns S.I., tab. XXI ; V. elongata, Sw., var. genuina, Rac, Flor., Btz., I, 59. 



Rhizome creeping; scales dense, black, narrowed gradually from the 

 base to a fine, acuminate point, the edge serrulate. Fronds linear, 20 — 180 

 c.M. long, 3 — 10 m.M. broad, pendulous, the apex bluntish or more commonly 

 acute, the lower part narrowed gradually towards the base. Texture subco- 

 riaceous; cosla distinct; veins hidden or indistinct. Sori long; lips of the 

 grooves equal or the upper projecting a little beyond the lower. 



Trop. Asia ^ Polynesia, New South Wales. 



* (8a) ¥. zoisteri folia, Wma., Spec, V, 406; V. elongata, Sw., var. 

 zosterae folia, Rac, Flor., Btz., I, 59, — var. pellucida. 



Rhizome woody, wide-creeping; scales blackish, narrowed gradually from 

 the base to the acuminate, hair-pointed apex, the edge serrulate. Stipes 

 scattered, 1 — 5 c.M. apart, slender, 5 — 25 c.M. long. Fronds lanceolate or 

 linear-lanceolate, 1 — IV2 c.M. broad, 20 — 120 c.M. long, narrowed gradually 

 towards both ends, the apex acute, the base decurrent upon the stipe. Texture 

 coriaceous; costa distinct; veins visible but not very distinct. Sori long, 

 reaching nearly the base and apex of the fronds; lips of the grooves equal 

 or the upper projecting beyond the lower. 



Var. pellueida : Texture thinner, pellucid ; veins conspicuous. 



Malaya; Polynesia, Comores, Mascarenes. 



{8b) \. paebyisteiBiiiia, Christ, Philipp. Journ., II, 174. 



Rhizome creeping, the extremity crowned with black, crisped setae, the 

 rest naked. Stipes approximate, rufo-stramineous like the costa, ± 6 c.M. long. 

 Fronds 25 — 30 c.M. long, falcate, linear-lanceolate, acute (not long-acuminate) 

 + 1*/^ c.M. broad. Texture succulent; colour lurid-glaucous; costa flat but 

 distinct. Sori submarginal, constinuous from the base to the apex; indusium 

 (? lips of the groove) narrow, pale-coloured.

(8c) V. criiipomarginata, Christ, Bull. Herb. Boiss., 2e S^rie, 

 VI, 1007. 



Rhizome slender, creeping, sparingly clothed with thin, short, flaccid, 

 brown setae. Stipes approximate, slender, often filiform, green, 8 — 10 c.M. 

 long, widening gradually into the base of the frond. Fronds to ± 25 c.M. 

 long, the fertile ones the longest. Bai-ren fronds linear-lanceolate, to 1 % c.M.
