 1 in. br., subquadrate or rhomboidal in general outline, cut down to a narrowly- 

 winged rachis ; segm. 1-2 in. 1. ; erecto-patent, linear, crenulate at the margin, 

 with a considerable space between them ; a central casta and numerous short

Hab. Johanna Island, West Africa, Dr. KirJc, Sir F. Grey. — Probably a mere variety

 very gradually decurrent below, pinnatifid down to a broadly-winged rachis ; 

 colour bright green, texture delicately membranaceous ; lobes oblong, obtuse, 

 crenate at the margin ; a central casta in each, with 2 to 4 pairs of erecto-patent 

 branches ; spurious venules none, the margin ciliated ; sori 2 to 4 to each lobe,

 distance of the rachis ; segm. linear, erecto-patent, the lower 1 in. 1., with deep 

 rounded lobes ; substance thin ; central veins of the segments with 2 to 6 pairs 

 of lateral veins ; spurious venules none, the margin ciliated ; sori 1 to 3, placed 

 principally near the base of the segments on the upper side, the tube quite sunk, 

 the mouth broadly dilated, two-lipped. — V.D.B. Suj)pl. 2. p. 118. 



Hab. Jamaica. — Closely allied to T. miuosum, but diflferent in outline, and much more

 entire or divided more than halfway down into narrow linear lobes, texture 

 subcoriaceous ; veins thick ; spurious venules none ; sori 2 to 6 to a segment, the

 Suppl. p. 12. 



Hab. Trinidad, Demerara, and northern provinces of Brazil. — Near T. Bancroftii, but
