Hab. Hongkong, C. Wright. — We owe the discovery of this species to the United 

 States North Pacific Exploring Expedition of 1853-6, under Capts, Ringgold and 

 Eodgers, 



44. T. hwmile, Forster ; rhixome creeping, deeply intermatted ; St. J-| in. 1., 

 slender, winged above; fr. 1-2 in. 1., J in. br., bipinnatifid, lanceolate-oblong in 

 general outline, cut down to a narrowly-winged rachis ; segm. pinnatifid, with 

 simple or once-forked linear lobes ; substance membranaceous, surface and margin 

 naked ; a central casta only in each segment ; no spurious venules; sori solitary, 

 on the upper side of the pinnse, tube more or less exserted, the mouth spreading, 

 two-lipped.— JJ/fc. Sp. I. p. 123. Hi. Gr. Ic. Fil. t. 35.— -ft T. Endlicherianvm, 

 Presl ; fr. more elongated ; segm. narrower and less branched. T, ereotum, 

 Brackenridge. 



Hab. Java, New Zealand, and Pacific Islands. — T. aureum, Y. T>. B., differs from the 

 type by its longer and broader slightly-crisped segments. Probably a mere variety of 

 pyxidiferum. 



4&>'-a?'.'»fegfi^j^^^ Kunze ; rhizome long, wiry, wide-creeping, more or less 

 tomentose ; fr. l^Sm. apart, nearly sessile, 3-6 in.l., 1-]^ in. br., once-pinnatifid, 

 cut down to a broadly- winged rachis ; lower pinnas oblong, blunt, ^-1 in. 1., ^-J br,, 

 varying from nearly entire to cut down to a broadly-winged rachis. with linear 

 lobes ; texture membi-anaceous ; surface nearly naked or ferrugineo-tomentose, 

 especially on the veins ; veins prominent ; lat. veins of the pinnse parallel and 

 erecto-patent ; no spurious venules ; sori 1 to 12 to a pinna, placed at the edge of 

 the lower half on both sides, tube long, cylindrical, stalked, mouth scarcely 

 spreading. — Hk. Sp. 1. p. 121. T. ^Ajikq ^;aiij Parker, in Hk. Gtr. Ic. Fil. t. 201. 

 ■ — ;8, T. Tanaicum, Hk. ; fr. 6-9 in. L, linear, undivided ; sori in long rows on 

 both sides. 



Hab. Trop ical AmfiWBWifoom the West Indian Islands scnthward to Peru and the 

 South o^BSSffl^^^ very distinct plant, which corresponds to the genus Lacostea of Van 

 den Bosch, who makes nine species. 



46. T. palMdam, Blume ; rhizome wide-creeping, slender, tomentose ; St. 1-3 

 in. 1., slender but wiry ; fr. 2-6 jn. 1., I-I5 in. br., ovate-lanceolate acuminate, 

 bipinnatifid, just divided down to a naiTowly-winged rachis ; lower pinnce ovate- 

 ihomboidal, divided more than halfway down, and the lobes again slightly cut ; 

 substance subcoriaceous, both surfaces, when dry, often decidedly coated with 

 white, always more or less clothed with strong light-brown liairs ; veins broad 

 and few ; sori 1 to 4 to a pinna, axillary on the segments on both sides, the tube 

 nearly sunk, the mouth dilated, but scarcely two-lipped. — Hk. Sp. 1. p. 139. 

 T. glauco-fascum, Hk. Sp. 1. p. 128. *. 40. A. T. album, Blume, Hk. Sp. 1. 

 p. 129. 



Hab. Malayan Peninsula, Ceylon, Java, Sumatra, and Pacific Islands. — This cor- 

 responds to the genus Craspedoneuron of Van den Bosch, who makes four species. The 

 pallid hue of the dry frond is very peculiar, and the coating of hairiness is sometimes 

 very prominent, but is sometimes nearly deciduous, 



47. T. serratulum. Baker ; rhizome slender, wide-creeping ; st. slender, naked, 

 about \ in. 1. ; fr. under | in. 1., about \ in. br., oblong, or subrhomboidal in 

 general outline, pinnatifid down to a narrowly-winged rachis ; segm. erecto-patent, 

 in 2-6 pairs, linear, simple or forked, \ in. 1., under \ lin. br., toothed at the 

 margin, texture membranaceous ; a central costa only in each segment ; spurious 

 venules none ; sori 1 to 2, terminal on the upper segments, the tube exserted or 

 even stipitate, the mouth slightly two-lipped, deeply ciliated with sharp linear 

 teeth. 



Hab. On trees, Lohong Peak, Borneo. — ^Eesembling T. caVoescem, Lyallii, and dentiai- 

 latum in its toothed segments, but diflferent in other respects, and a very distinct 

 species.
