Y58 FERNS OF NORTH QUEENSLAND, 



ginatum, but says of T. muscoides Sw., "durch die Tropen allei 

 Welttheile." Sadebeck, in Pflanzenfamilien (1899), takes the 

 same view, and merges T. himarginatum in T. muscoides, accord- 

 ing to earlier determinations. Luerssen, in " Fil. Gr?ef." (1871), 

 held that T. himarginatum was not distinguishable from T. mus- 

 coides Sw. This opinion he recalled in Bot. Centralbl., ix., 12 

 (1882). Christensen, in Index Filicum (1906), separates these 

 plants and limits T. muscoides to tropical America. Domin 

 follows Luerssen and Christensen in this. Bailey's T. yandineuse 

 appears to be identical with T. himarginatum. F. von Mueller 

 identified T. yandinense with T. cuspidatuin Willd., but this 

 species is apparently limited to Madagascar and E. and W. 

 Africa. 



A plant collected by me at Josephine Creek, where it was 

 plentiful on the stems of trees, I at first regarded as T. himar- 

 ginatum, with which it agrees in its submarginal spurious vein: 

 but the description of T. himarginatum in A. van Rosenburgh's 

 "Malayan Ferns," is " oblong- lanceolate, not lobed, sometimes 

 bitid at apex.' With this the tig. (PL iii.) in Domin agrees, as 

 do also my specimens from Kuranda. The Josephine Creek 

 plant is cuneate-oblong, distinctly and often deeply lobed, with 

 crenulate and undulate margins ; the spurious veins also are 

 stronger and fewer. In general outline it resembles the fertile 

 frond of T. cuspidatum, according to Christ's figure, and is 

 apparently the plant figured by Bailey in Q. Bot. Bull. No. 13 

 (1891), and described as 7\ muscoides Sw. Believing it to differ 

 from all the three plants named, I have ventured to describe it 

 as a new species, and have dedicated it to the veteran pteridolo- 

 gist, Mr. F. M. Bailey.
