208 THE VOYAGE OF H.M.S. CHALLENGER. 



CRYPTOGAMS. 



FILICES. 



The fern vegetation of the Malayan Archipelago is very rich and varied, and the small 

 collection made by Mr Moseley in the South-eastern Moluccas contained several new 

 species. Mr J. G. Baker published a complete enumeration of all the ferns collected 

 by the Challenger Expedition in the Malayan Archipelago and Polynesia, in the fifteenth 

 volume of the Journal of the Linnean Society of London, together with descriptions of the 

 new species. The following were collected in the South-eastern Moluccas by Mr Moseley. 



Alsophila polyphlebia, Baker. 



Alsopliila pdlypMeUa, Baker in Journ. Linn. Soc. LonJ., xv. p. 104. 



Height of trunk up to 25 feet. — Frond ample, tripinnate. Bachis of pinna? pale brown, 

 slightly furfuraceous and rough with raised points. Pinna? oblong-lanceolate, 2 feet 

 long, 7-8 inches broad. Pinnules sessile, lanceolate-ligulate, 3j to 4 inches long, an inch 

 broad, cut down to the rachis into close, blunt, distinctly crenated tertiary segments, 2 

 lines broad. Texture thin, but firm. Both surfaces glabrous, the lower with a few minute 

 bullate scales on the midrib of the tertiary segments. Veinlets 12-14-jugate, close, fine, 

 distinct, deeply forked, the lowest one sometimes twice forked. Sori placed close to the 

 costa, and a space from the edge, with a distinct space between each, sometimes 12-15 to 

 a segment, absent from the upper third of the segment.
