Sori marginal, lateral, or terminal, sometimes upon a changed 

 frond and forming a spike, free or united or sunk in the frond, 

 always terminating a vein. Involucres monophyllous, tubu- 

 lar, subcylindrical, tapering at the base, more or less spread- 

 ing at the mouth, sometimes two-lipped, of the same texture 

 as the frond or thicker and more compact, entire, rarely 

 toothed or serrated. Receptacle elongated, columnar, or 

 more frequently fdiform, much exserted, sometimes to a very 

 great length. Capsules sessile or nearly so, clothing the base 

 (}f the receptacle within the involucre, rarely the npper por- 

 tion also, depressed, surrounded by an entire, broad, nearly 

 transverse riny, bursting on one side vertically. Sporulcs ;3- 

 angular or 3-lobed ; in the subgenus Hymenostaclnjs oval. — 

 Ferns usually of small size, but varyiny from 2 incites to 2 

 feet in lenytli, inhahiting the tropics or temperate climates. 

 Caudex generally more or less creeping, JiUform or stout, gla- 

 brous or lomentose : sometimes apparently wanting. Fronds 

 more or less stipitate, sometimes sessile, of a membranaceous 

 rarely subcoriaceous texture, generally loosely reticulated, 

 but occasionally fi/iT. reniformcy' very closely and compact ly 

 so, the mesJies or areola; mostly placed without order, but 

 sometimes (in T. membranaceum and its allies) arranged 

 in lines corresponding with the direction of the venation ; 

 generally of a deep green color, darker and brownish or al- 

 most black U'hen dry ; glabrous or hairy, rarely fringed with 

 scales ; simple or pinnated or pinnatijid, and variously di- 

 vided, with narrow oblong or linear segments, which are in- 

 cised or usually undivided, entire, seldom toothed or serrate, 

 with a strong costa or vein in the centre: sometimes the veins 

 radiate from the base (as in T. reniforme bfc.) in a very ele- 

 gant manner.— Hook. Gen. Fil. Tab. 31. Tah. 108. (Ily- 

 menostachys, Bory). Hook. Ex. Fl. Tab. 52. (Feea, Bon/).
