densely so, the scales peltate, copiously ciliate to fimbriate, partially smallc 

 and decoloured, partially larger and cinnamon-coloured; costa prominent, n 

 fous, rather sparingly scaly ; veins hidden, horizontal. Fertile fronds lineai 

 to ± 35 c.M. long, + 1 c.M. broad; upper surface densely scaly, lowe 

 densely soriferous.

Sori indefinite; sporangia densely crowded over the under surface of th 

 much contracted or narrovred, + linear pinnae of the fertile fronds. 



Rhizome woody, high-scandent, often reaching the tops of the highes 

 trees. Fronds pinnate, dimorphous or polymorphous, whether or not articu 

 late to the rhizome, the abnormal barren fronds, when present, variously an( 

 often finely divided, the fertile fronds Lomaria-like ; veins free, simple oi 

 forked, those of the fertile pinnae sometimes slightly anastomosing, but alwayi 

 united at the base by a more or less distinct or spurious, + costal, trans 

 versing vein, those of the barren pinnae sometimes so. Hk. Bk., Syn. Fil.

Arrangement of the sections. 



§ 1. LOMARiOPSIS. Barren fronds uniform; abnormal fronds wanting. 



§2. TERATGPHYLLUM. Barren fronds dimorphous; abnormal fronds present 



§ 1. LO.VIARIQPSIS. 



It. Barren pinnae not articulate to the rachis, cordate at the base. 



(1) S. laurifolia 

 u>a. Barren pinnae articulate to the rachis. 



b. Barren pinnae unequal-sided at the base; upper base rather truncate, 

 lower + cuneate. (2) S. arthropteroides. 



(*) The fertile pinnae hate the edges not rarely recurved, ± modiiied and indnsiam- 

 like, and then it is rather difficult to distinguish the species from Lomaria, except when the 

 rhizome is shown.
