(235) L.. regularis, Rst., in Med. R. H. L., 1912, is, 31. 



Stipes + half a long as the fronds, compressed, angular, livid-brown, 

 the base asperulous and provided with scattered, ferrugineous scales.

 Branches elongate-lanceolate, 10 — 15 cm. long, I'/i — 2 cm. broad at the 

 middle, acuminate, slightly narrowed at the base ; terminal branch longest, 

 short-stalked; lateral branches shorter, subsessile. Leaflets numerous, 

 sessile, close or approximate, horizontal or nearly so, linear-oblong or the 

 lower anterior ones obliquely conico-flabellate, bounded by a marginal 

 vein; largest leaflets 7*/j — 10 mm. long by 3—4 mm. broad at the middle, 

 slightly dilated at the base, the apex rounded or rotundate-truncate,
