FILICES. 657 



Hedw. Fil. t. 3./. 5. Pr. Hymenoph. t. 9.— Hemiphlebium, Pr.— Leaf 4"'-8'" long, ta- 

 pering into the short petiole.— Hab. Jamaica !, Wils. ; Trinidad !, Pd., Lockh., on trees, 

 near the summit of Mount Tocuche ; [New Granada !, Peru !, Brazil ! j often growing inter- 

 mingled with T. muscoides']. 



47. T. muscoides, Hook. Grev., Sw. Fl. (non ej. Synops.). Leaf cuneate-oblong, or 

 obovate, bluntly sinuate, petioled (or subsessile), glabrous, striated between the distant, al- 

 ternate, forked veins, the later connected by a juxtamarginal streak ; indusium included: 

 limb very shortly 2-lipped, very shortly exserted : column shortly exserted.— SI. t. 27./. 1 : 

 only the inferior larger leaves. Hook. Grev. Ic. t. 179. Pr. Hymenoph. t. 6. B— T. 

 Hookeri, Pr. Microgonium Berteroanum, Pr.— Leaf 12"'-4'" long, 6"'-3"' broad, rarely 

 larger: petiole shorter than the blade. — Hab. Jamaica!, Al., Wils., on trees; Dominica!, 

 Imr., S. Vincent; Trinidad!, Or.; [Cuba!; Venezuela!, Guiana!, Brazil!, Peru!]. 



_ 48. T. apodum, Hook. Grev. Leaf cordate-roundish, pinnaiilobed and crenate- 

 sinuate, sessile, or subsessile, glabrous with a few marginal hairs, remotely and shortly 

 striated along the margin between the distant, simple, pinnate veins : midrib S-parlite ; 

 indusium exserted, margined below towards the base : limb deeplv 2-lipped : column long- 

 exserted.— Hook. Grev. Ic. t. 117.— T. hymenoides, Hedw. {Fil. t. 3./. 3)?: too badly 

 figured and described to merit restoration. T. muscoides, W., Kze., Sw. Synops. (non Fl. Ind. 

 Occ.) -. Swartz not having distinguished the allied species, his name comprises T. mus- 

 coides, apodum, and sphenoides. 1° The description of Fl. Ind. Occ. (" urceoli inclusi," 

 p. 1726, repeated in contradistinction of T. reptans, var., p. 1728) can only be referred to 

 T. muscoides, Hook. 2° The diagnosis of Synops. Fil. ("urceoli exserti," p. 141) belongs 

 partly (as far as it agrees with Hedwig's synonymy), to T. apodum, verified by Kunze in 

 Willd. Herb. 3° The quotation of Sloane (t. 27. f. 1), insisted upon by a special observa- 

 tion (Fl. p. 1726) is remarkable as proving a confusion of T. muscoides and T. sphenoides, 

 which both (growing intermingled) are well to be recognized in that figure, though the pin- 

 nate veins of the larger leaves (T. muscoides) by the artist are wrongly transferred to the 

 rest (T. sphenoides). Thus it appears much more advisable to preserve the names employed 

 for the excellent figures of Hook, and Grev., than, as Presl and Kunze have proposed, to 

 restore Swartz's authority from his specimens, which in the case of T. muscoides prove 

 to be in contradiction with his own primary description. — Leaf 3"'-6'" diam. .- all lobes 

 and crenatures rounded. — Hab. Jamaica (Sw.) ; Barbadoes !, Parker ; [Cuba!; Mexico to 

 Venezuela]. 



49. T. reptans, Sw.(exclus.var). Leaf cuneate-obovale, pinnatilobed (or spathulate, 

 subentire), shortly petioled, ciliate with stellate hairs : lobes blunt, entire : midrib excurrent : 

 veins and veinlets pinnate, both arched towards the margin, the latter approximate, ofteu 

 forked above ; indusium margined beyond the lobe : limb 2-lipped to the base. — Hedw. Fil. 

 t- 3./. 4. — Kunze (Bot. Zeit. 5. p. 279) is so far correct in his observations, that this spe- 

 cies is distinguished from his T. sphenoides by pinnate nervation (indeed together with the 

 tapering, but excurrent, strong midrib the only clear difference of both spee'es, which how- 

 ever, as veins and veinlets ruu in a flabellate manner towards the margin, possibly may 

 prove fallacious) : but at the same time he has confounded T. reptans with two other species, 

 viz. T. quercifolium, Hook., and T. Kraussii, Hook. Grev. (T. reptans, Kze. ! in PI. Kegel.), 

 which both are deprived of the numerous, densely approximate veinlets, so characteristic for 

 T. reptans and T. sphenoides— Leaf 12"'-4'" long, 5^-1"' broad, cuneate dr tapering at the 

 base.— Hab. Jamaica !, Wils. ; [Cuba (Pcepp.) ; Venezuela (AT/.)]. 



50. T. sphenoides, Kze. Leaf roundish, or obovate, cuneate or contracted at the base, 

 sinuate-lobed or repand, ciliate with stellate hairs : veins flabellate-dichotomout, approxi- 

 mate, midrib distinct below the middle : petiole shorter than or as long as the blade ; in- 

 dusium margined beyond the blade : limb 2-lipped to the base.— Hook. Grev. Ic. t. 32. 

 Kze. Farnkr. t. 88./. 2.— T. reptans, Hook. Grev. T. reptans, var., Sw. Fl. (p. 1728).— 

 Leaf 3"'-6'"(-8'") long, 3"'-5'^ broad : petiole 3"'-l"' long— Hab. Jamaica !, Pd., Wils., 

 on trees j S. Vincent !, Guild., Barbadoes ; [Cuba ! to French islands ! ; Venezuela ! to Bra- 

 zil ! and Peru]. 



51. T. punctatum, Poir. Leaf roundish, rounded or subcordale at the base, sinuate- 

 crenate, or repand, glabrous, or with a few stellate hairs at the margin, remotely striated be- 

 tween the flabellate-forked, distant veins ! midrib short, or none : petiole very short, or
