 elevation. Its fronds, 2ft. to 4ft. long, 1ft. to lift, broad, and borne on 

 brownish, naked stalks 1ft. or more in length, are produced from a creeping 

 rhizome (prostrate stem). They are composed of a terminal leaflet and from 

 two to six pairs of lateral ones, all large, oblong in shape, variously forked, 

 .especially the lower ones, and of a leathery texture, the principal veins 

 being distinct to the edge. The small, abundant, scattered sori (spore

 disposed along the midvein, and covered with a small, smooth, persistent 

 involucre. — Hooker, Synopsis Filicum, p. 494. 



N. (Lastrea) Preslii— Las'-tre-a ; Presl'-i-i (Presl's), Baker. 



A stove species, of small dimensions, in general appearance resembling

 (spore masses) disposed close to the base of the obscure veinlets. — Hooker,
