Stip. slender, 6—15’ long, stramineous or brownish, glossy, pa- 
leaceous below with dark brown gga long-acuminate sparingly 
glandular scales of 4—6 in length. Frond open, thin chartaceous, 
rather pale, glossy, deltoid-ovate, penne 8—15’ long, with a 
naked or fibrillose rhachis, bi-, tripinnate. Stipitate pinnae 7—11 on 
a side, al anadromous from the base, subascending; the lowest on stalks 
of 3—12“, deltoid, much broader in the lower half, 5—8‘ long. Lowest 
secondary pinnae the largest, 3—4‘ long, deflected outward. Tertiary 
segments or pinnules 1/2—1/ long, sessile and decurrent or shortly stipitate 
with a cuneate or unevenly truncate base, obtuse or bluntly pointed, 
notched or deeply cut into ovate or oblong lobes which point toward the 
apex and are mucronate with 1—3 closely approximate teeth. Veinlets 
at acute sires simple or forked, the upper basal branch ending in a 
sinal tooth. Sori subterminal on raised receptacles, copious, large, in less
