4. V. remota, Fee. — Rootstock slender, short, erect, the scales very- 

 minute, reticulated, and dark ; stipites csespitose, erect, few to a plant, 

 purple, short, winged by the decurrent fronds to near the base; fronds 

 erect or suberect, f— \\\ ft. 1. J— ^ in. w., tapering gradually both ways, 

 the apex acuminate, very rarely forked, pellucid, chartaueous, a bright 

 glossy green, pale beneath, margins thin and slightly reflexed or 

 bevelled, sometimes irregularly narrowed and forming a shallow notch 

 in the line; midrib evident, raised on the upperside, the base dark 

 purple; veins close, about 1 1. apart, connected exteriorly within the 

 margin, and also casually interiorly; sori forming a dark-brown band, 

 superficial, or the receptacle, very slightly depressed, continuous or 

 interrupted. 



Rare in forests on decaying logs of wood, growing in grass-like 

 masses, gathered at Chesterfield, St. Mary. A well marked but rather 

 anomalous species, distinguished by the superficial broadish bands of 

 sori, the close veins, which casually form medial conn ctions as well as 

 the normal exterior anastomosis, and the distinct midrib. The veins 

 though immersed (as is also the midrib) are slightly raised on the upper 

 side. The texture while fresh is pellucid, and the colour a very fresh 

 bright green. 



Genus XXXIV. T^mtis Swartz. 



Sori linear, continuous or interrupted, rarely in oblong patches, sub- 

 marginal, intramarginal or medial, superficial or more or less impressed 

 or sunk in a narrow furrow; veins freely reticulated or the veinlets 

 connected by a transverse longitudinal vein, which forms a linear or 

 elongated receptacle; fronds simple, furcate or pinnate, generally cori- 

 aceous, naked or slightly scaly; rootstock shortly repent or free- 

 creeping. 



A very small genus, much resembling the preceding, but dis- 

 tinguished by its more superficial sori, generally copiously reticulated 

 venation, stiffer and coriaceous texture of leaf, and erect or less pendent 

 habit. There are barely a dozen species, all tropical, two-thirds of 

 which are American, and the others Asiatic. They are all epiphytal, 

 growing on the branches and stems of trees, mostly in moist districts 

 or situations. 



Fronds simple. — 1. T. Swartzii. 



2. T. angustifolia. 



3. T. lanceolata. 



1. T. Swartzii. Jenm. — Rootstock free-creeping, thick as slender 

 cord, dark tomentose-scaly in the extending part; fronds scittered, 

 4-6 in I. in or more wide, acuminate, tapering at the base and 

 decurrent on the short purple petioles, which are i-l| in. 1 , elastico- 

 coriaceous, opaque, thinly sprinkled with minute peltate fimbriate-edged. 

 scales, underside paler than the upper, costae purple, thread-like 

 upwards ; veins immersed, hidden or obscure, reticulated, thi areolae 

 elongated and parallel with the costae and margins , sori superficial, 

 intramarginal, continuous or interrupted, mostly in oblong patches in 

 pmall fronds, confined to the upper part. Grammitis elonjata, Swartz.
