11. T. Godmani, Hk. MSS. ; fr. tomentose, strong, |-| in. 1., \-\ in. br., sub- 

 orbicular or obovate, the margin entire or slightly lobed ; venation flabellate 

 above, but the frond furnished with a distinct central costa through the lower 

 half ; spurious venules indistinct ; sori 1 to 9, the tube quite sunk in the frond, 

 the mouth dilated, entire. 



Hab. Guatemala, Salvin & Oodman; Panama, Hayes. Similar to T. Motleyi in habit, 

 but quite different in the fruit. 



12. T. punctatum, Poiret ; fr. stalked or subsessile, J-J in. br., suborbicular or 

 obovate, undulated or slightly lobed at the margin ; veins closely placed, with 

 thick prominent spurious venules between them ; sori 1 to 4, placed on the 

 outer edge of the frond, and more or less exserted, the mouth distinctly two- 

 lipped. -#. Sp. I. p. 116. Hk. Sf Gr. Ic. Fil. t. 236. Hemiphlebium, V.D.B. 



Hab. Tropical America, both the islands and mainland. 



13. T. reptans, Swartz ; st. % in. 1. ; fr. -| in. br. each way, obovate-cuneate, 

 often with short blunt lobes ; veins close ; spurious venules conspicuous ; sori 

 1 to 4, placed on the outer margin, tube partially or quite exserted, the mouth 

 distinctly two-lipped. #. Sp. 1. p. 116. Hk. & Gr. Ic. Fil. t. 32. Hemiphle- 

 bium, V. D. B. T. sphenoides, Kunse in Schk. F. t. 88.^. 2. in greater part. 



Hab. Tropical America, both the islands and mainland. There has been considerable 

 confusion between this species and the preceding, which are very closely allied . 



ft Fronds with a distinct central costa from apex to base. Sp. 14-20. 



14. T. Barklianum, Baker ; fr. very shortly stalked, 2-3 lin. 1., 1 lin. br., 

 linear-oblong, entire, the margin undulated ; veins pinnate ; spurious venules 

 none ; sori solitary, terminal, the tube partially exserted, with a large dilated 

 entire mouth. Baker in Linn. Proc. inedit. cum icone. 



Hab. Tamari Cascade, Mauritius. A very interesting novelty, the discovery of which 

 we owe to Sir Henry Barkly, the Governor of Mauritius, and Lady Barkly. 



15. T. Vitiense, Baker ; fr. subsessile or very shortly stalked, oblong, entire 

 or rarely bifid, 2-4 lin. 1., 1-2 lin. br., furnished with a midrib only ; lat. veins 

 none ; spurious venules none ; sori solitary, terminal, the tube partially exserted, 

 the mouth entire, slightly dilated. Baker in Linn. Proc. inedit. cum icone. 



Hab. Fiji Islands, Milne. This species rivals in minuteness Hymenophyllum parvifo- 

 lium and the preceding. From this latter it is readily distinguishable by the absence of 

 lateral veins, and the two are the only pinnate-veined species that are without spurious 

 venules. 



16. T. Neilgheriense, Beddome ; st. 1-2 lin. 1. ; fr. -$ in. 1., 1-2 lin. br., oblong- 

 lanceolate, not lobed, but sometimes bifid at the apex ; spurious venules nume- 

 rous ; sori 1 to 2, the tube more or less sunk in the frond, the mouth exserted, 

 with two large rounded lips. Bedd. Fil. S. Ind. t. 6. 



Hab. Western slopes of the Neilgherry range, S. Hindostan, discovered and figured by 

 Captain Beddome. 



17. T. Petersii, A. Gray ; st. 1-2 lin. 1. ; fr. - in. 1., 1-2 lin. br., varying in 

 shape from linear to obovate-spathulate, crenate or slightly lobed ; spurious 

 venules few, short and often unconnected ; sori solitary, terminal, the tube sunk 

 in the frond, the mouth much dilated, but entire. A. Gray, in Sill. Am. Journ., 

 1853, p. 326. Hk. Ic. PL t. 986. Microgonium, V. D. B.
