Hab. Arfak Mts., Angi lakes, 7000’, spinney by ? lake, undergrowth in 
forest. Dec. 5968. ‘'Tree-fern, 3m. in height, brown palew on young 
stem and fronds. Brown and with thorns on old.” 
This plant is represented by two pinne which are entirely sterile. It is 
tentatively referred to Alsophila. In some respects it recalls A. glauca, but 
differs in having the pinnules crowded together and imbricated, and the 
rhachises dull and unpolished. The pinnules are inserted on the pinna- 
rhachis at intervals of about 1:25 cm. and overlap; the middle pinnules are 
horizontal, the lower are deflexed.

Hab. Arfak Mts., 8.W. ridge, Angi lakes, 7000-8500’, common under- 
growth in moss-grown forest. Dec. 5990. Also common about ? lake, 
in forest. ‘Slender tree-fern, stem 1 dm. in diameter and 1 m. in height.

The material consists of the two lowest pinnz and the top 37 em. of a 
frond. A small dark gland is present at the base of the stalks of the 
pinnules.
