 S. Vincent !, Guild. ; Trinidad ! j [Cuba ! and Mexico I to Brazil ! and Peru !]. 



$ 5. Indusia confined to the lowest part of the upper margin of the leaf-segments (rarely 

 appearing on both margins) : otherwise like § 4. 



* Leaf pinnatipartite, subsessile ; ("indusia sometimes on both margins). 



36. T. Ankersii, Parker. Leaves scattered, pinnatipartite, subsessile, glabrous : seg- 

 ments approximate, horizontal, oblong, blunt, obtusely serrate, fertile usually at the lowest 

 serratures of the upper margin, rarely ou both margins : veinlets pinnate, mostly simple : 

 short streaks between them; indusium wholly exserted: limb spreading, truncate. — Hook. 

 Grev. Ic. t. 201.— Leaf turning blackish in drying, 3"-8" long, l"-2" broad.— Hab. S. Vincent 

 {J. Sm.) ; Trinidad (V. d. Bosch) ; [Panama, Guiana !]. 



37. T. brachypus, Kze. Leaves scattered, pinnatipartite, subsessile, glabrous: seg-, 

 ments pinnatifid, nearly horizontal; lobes spreading, linear, blunt, or 2-3-fid, inferior of 

 both margins or lowest only of the upper margin fertile : most veinlets simple : no streaks ; 

 indusium wholly exserted, stipitate, or margined at the base : limb short, subentire. — 

 Hook. Grev. Ic. I. 218.— Leaf 2"-8" long, l"-3" broad.— Hab. S. Vincent !, Guild. ; Tri-

** Leaf 2-S-pinnatipartite, petioled : petiole above and rhachis margined. 



38. T. pyxidifertun, L. Leaves scattered, 2-3-pinnatipartile, narrowly decurrent into 

 the short petiole, glabrous : ultimate segments linear, emargiaate, or blunt, each wit h a 

 simple veinlet and 2 long parallel streaks between it and the entire margin ; indusium free, 

 margined at the base, sessile on the upper margin of the primary segments near their base, 

 half as long as the column : limb spreading, subentire. — Plum. Fit. t. 50. E. — Leaf 5"-l" 

 high, 12"'-6'" broad. — Hab. Jamaica (Sw.), in mountain-woods; [Cuba! to Brazil! and 

 Pern !]. 



39. T. brasiliense, Desv. Leaves scattered, 2-pinnatipartite, very narrowly decur- 

 rent into the petiole, glabrous : secondary segments few-lobed or pinnatifid, or entire, ulti- 

 mate oblong-linear, emarginate, or blunt, each with a simple veinlet, but no streaks ; itidnsium 

 margined to the spreading, subentire limb, usually much shorter than the column, sessile on 

 the lowest inner lobe or on the upper margin of the primary segments near their base.—

 Hook. Grev. T. emarginatum, Pr. T. leptophyllum, V. d. Bosch.— Habit of the prece- 

 ding, but petiole naked below, wing at its summit much narrower (while the rhachis of 

 the primary segments is nearly as broad), and easily distinguished by the wanting streaks, 

 peculiar to T. pyxidiferum. Leaf l"-4" high, 6"'-12'" broad : petiole 6"'-l 2'" long.—
