Selliguea albidosquamata (Bl.) Parris 
original distr. as Crypsinus albido-squamatus (Bl.) Copel. 
New Ireland, Hans Meyer Range; Angil Mountain, pristine subcloud forest 
dominated by bryophytic and ferny growth, elev. c. 1800 m, centered 
around 152 deg. 56.8' E x 4 deg. 25.2’S (coll, site 4). 
with sequence starting Lycopodium 9339; common epiphyte; rhizome 
long-creeping, densely squamose, paleae: peltate, ferruginous (margins 
pale), cauda upturned and spreading; stipes to about 20 cm long, 
articulated to paleaceous phyllopodia, glabrous, smooth, shiny brownish- 
black, essentially terete, not channelled, vasculature of one or two 
strands; fronds avg. 50 cm length, pinnately compound; lamina firm, 
glabrate, upper surface dull dark green and marked with conspicuous 
lime dots on the soral disk and blade margin, underleaf light green; 
pinnae conform, subequal in length, linear, typical 22 cm x 2 cm, apex 
attenuate, margins subentire, base cuneate and stipitate: equal or not; 
venation regularly anastomose with 2 costal ranks of large areoles, each 
areole containing one sorus, included veins pointing in all directions, their 
ends capitate, other veins extending straight to the margin from the 
commissural nerve, the distal ends also dilated in a hydathode; sori 
round, exindusiate, forming medial rows on each side of the costule.
