1. V. elongata (elongated), Swartz ; Hook, and Bale. Syn. Filic. 395; Benth. 

 Fl. Austr. vii. 718. Rhizome creeping, covered with black or purple hair-like 

 scales. Fronds varying from 2 or Bin. to 2ft. in length, 1 to 2 lines broad when 

 fertile, 2 to 5 lines when barren, acute obtuse or truncate at the end, gradually 

 tapering into a short stipes, of a rather coriaceous texture. Veins very oblique, 

 sometimes almost parallel with the midrib and all as well as the midrib embedded 

 in the substance of the frond. Sori usually extending nearly the whole length of 

 the fertile fronds. — R. Br. Prod. 153 ; Leurss. in Schenk and Leurss. Mittheil. 

 Bot. i. 90, t. 11 ; Bedd. Ferns S. Ind. t. 21 ; Bail. Litho. Ferns Ql. 50.

2. v. falcata (sickle-shaped), Kunze ; Fee, Vittar. p. 20, t. 4, /. 1 ; Hook. 

 Spec. Filic. V. 182 ; Syti. Filic. 395. Fronds 4 or 5in. long. |^in. broad, the 

 point blunt, the lower part narrowed gradually to the base ; texture leathery 

 "and very thick ; a distinct raised midrib attaining the apex in the barren fronds, 

 but lost in the fertile ones ; veins short, oblique, parallel, immersed ; sori quite 

 sunk in slightly intramarginal grooves. 



Hab.: Bellenden-Ker.— Sajrer, F. v. M. Sou. Soi. Eeo. 1887. 



3. V. wooroonooran (the aboriginal name for Bellenden-Ker), Bail. 3rd 

 Suppl. Syn. Ql. Fl, 92. Rhizome erect or slightly repent, clothed with long, 

 light-brown, linear-lanceolate scales. Fronds 1 to l|in. long, 2 to 3 lines broad, 

 coriaceous, spreading horizontally, very obtuse, tapering to a very short stipes, 

 bearing minute, scattered, setose scales ; veins once forked from a central costa, 

 but both concealed by the thick substance of the frond ; sori continuous in a 

 groove more or less distant from the margin on the upper part of the frond, 

 but never meeting at the apex. — Bail. Litho. Ferns, Ql. 50. 



Hab.: On rocks amongst moss at an elevation of from 4,000 to 5,000ft., Bellenden-K«r. 

 In some respects this species approaches V. falcata. 



19. LINDS.ffiA, Dryand. 

 (After Dr. Lindsay.) 

 Rhizome creeping or shortly horizontal. Fronds pinnate or compound. Sori 

 in a continuous or rarely interrupted line under the margin of the frond, with a 

 continuous indusium opening along the upper or outer margin, the margin of the 

 frond sometimes slightly dilated and assuming the appearance of an upper valve. 

 Veins forked, free or anastomosing. 



A considerable tropical and subtropical genus, common to the New and the Old World. 

 Pinnules obliquely flabellate, one aide of the base longer than the inner. 

 Rhizome creeping. Fronds simply pinnate ; rhaohis black, wiry. Pin- 

 nules small, distant 1. L. linearis. 



Rhizome short. Fronds tufted, simply pinnate; rhachis slender. Pin- 

 nules small, distant, often bipartite 2. L. dimorpha. 



Rhizome short. Fronds tufted, simply pinnate. Pinnules near together, 



3 to 4 lines broad 3. L. cultrata. 



■Rhizome creeping. Frond pinnate and l)ipinnate Pmnules often Jin. 

 broad. 



Veins forked, all free or very rarely anastomosing i. L. flabellulata. 



Veins in most of the pinnules more or less anastomosing . . . . 5. L. lohata. 

 Pinnules obovate or cuneate, equilateral. Veins free.

trunoate, 1 to 2 lines long 6. i. microphylla.

 cuneate lobes, 1 to 2 lines long 7. i. incisa.
