below, is sometimes nearly lost upwards. The spore masses are disposed in 

 broad, continuous, sub-marginal lines, with, the firm, unaltered edge of the frond 

 at first wrapped over them. This plant is a native of New Guinea, Malaysia, 

 the Neilgherries, Ceylon, the Seychelles, &c. — Hooker.^ Species Filicum, v., 

 p. 117. Nicholson, Dictionary of Gardening, iv., p. 188. 



Y. (Tseniopsis) Stipitata — Ta3n-i-op'-sis ; sti-pit-a'-ta (stalked), Kunze. 



The habitat of this species extends from Columbia to Peru. Its fronds, 

 l^ft. to 2ft. long and scarcely Jin. broad, gradually taper below into a long, 

 slender stem ; they are of firm texture, with an indistinct midrib except 

 towards the base. The spore masses are sunk in a groove within the margin, 

 with the. flattened, thickened edge of the frond produced beyond it. — Hooker, 

 Species Filicum, p. 179. 



Y. (Teeniopsis) Stricta — Tfen-i-op'-sis ; stric'-ta (upright), Carmichael. 



A species from Tristan d'Acunha, with thick fronds IJft. long, |in. broad, 

 and narrowed below to a compressed stem ; a stout midrib extends to their 

 summit, the spore masses occupying the whole space between it and the 

 much-reflexed edge.^^Rooker, Species Filicum, v., p. 182. 



Y. (Taeniopsis) sulcata — Taen-i-op'-sis ; sul-ca'-ta (furrowed), Kuhn. 



This species, native of Ceylon and the Society Islands, produces from 

 a short-creeping rhizome its strap-shaped, stalkless, blunt fronds, which are 

 narrowed to the base, 2in. to 4in. long, and Jin. broad. The midrib is visible 

 only in the barren lower half of the fronds. The spore masses are disposed 

 in a deep, intramarginal furrow confined to the very much thickened upper 

 half of the frond, where the midrib and veins are quite lost. — Hooker, Synopsis 

 Filicum, p. 518. 



Y. zosteraefolia — zo-ste-ras-fol'-i-a (Zostera-fronded). Synonymous with 

 V. elongata. 



In addition to the species above described, we may mention V. (Tceniopsis) 

 dehilis of Kuhn, and F. (T.) pumila of Mettenius, both diminutive plants of 

 botanical interest only.
