 Bessile fronds and more distant veins ; and V. Jiuiziana, F^e, superficial sori and a flat- 

 tened stem. 



6. V. (Taeniop.) stricta, Carm. ; fr. 18 in. l.j \ in. br., narrowed below to a 

 compressed stem ; texture thick ; midrib stout, continued to tiie apex ; the sori 

 occupying the whole space between it and the much reflexed edge. — Hk, Sp. 5.

7. V. (Taeniop.) lineata, Sw. ; fr. 6-18 in. 1., ^-§ in. br., narrowed gradually 

 downwards to a stout compressed stem, which passes into the frond gradually, 

 the edge often reflexed ; texture firm, a distinct raised midrib running from the 



,base to the apex-; veins immersed, parallel, very oblique ; sori in a broad slightly 

 intramarginal line in a slight furrow, the edge of the frond at first wrapped over 

 it— HL /S>. 5. p. 180. 



Hab. Japan, West Indies, and Florida to Peru and Brazil ; Himalayas, Neilgherries, 

 Malaccas, Mascarea Isles, Guinea Coast, Zambesi-land, Natal; Cape Colony. — Of M. F^e's 

 species we include here lineata and jilifolia (Tropical America), jlexuosa (Hindostan), 

 tenera and sarmeniosa (South Africa), and guineensis (Guinea). 



8. V. (Tseniop.) re?nota, Fe'e ; /r. 12-18 in. 1., §-| in. br., naiTowed gradually 

 to the base or a short compressed stem ; texture moderately firm ; midrib dark- 

 coloured and distinct below, but often lost before it reaches the apex ; vei7is 

 immersed, very oblique ; sori in a broad superficial distinctly intramarginal line, 

 with the edge not at all wrapped over it. — Hk. Sp. 5. p. 185, 



Hab. West Indies to Ecuador. — Distinguished from the other American species by its 

 broader flat frond and the position of the sori. It is very like 2'ienitis angustifolia in 

 general habit, but the veins are free. 



9. V. (Tsniop.) scolopendrina, Thw. ; fr, 12-18 in. 1., ^-| in. br., the point 

 acute, the edge entire, the lower part narrowed very graduall}^ to the base ; 

 texture thick ; midrib thick, blackish, grooved in front below, sometimes nearly 

 lost upwards ; veins oblique, fine, simple, parallel ; sori in broad continuous 

 submarginal lines, with the firm unaltered edge of the frond at first wrapped 

 over it. — V. Forbesii and zeylanica, Fee. Hk. Sp. 5. p. 177. 



Hab. New Guinea, Philippine and Malayan Isles, Neilgherries, Ceylon, Seychelles, 

 Mozambique. — F. loricea, Fee, appears to be closely allied, but the Himalayan plant 

 mentioned in " Sp. Fil." is referred to V. scolopendrina by Mettenius. The largest and 

 finest of the group. 



Gen. 57. T^enitis, Sw. 



Sori linear, but the line sometimes interrupted, central or submarginal. A 

 small genus of not very closely allied sjjecies, all tropical. Some of the sp)ccies 

 scarcely differ from Tsniopsis in fniit, but in all those placed here the veins ana- 

 stomose. Tab. VI. fig. 57.
