[Jab. Arfak Mts., Angi lakes, 7000', spinney by ? hike, undergrowth in 

 forest. Dec. 5968. " Tree-fern, 3 m. in height, brown paleze on young 

 stein and fronds. Brown and with thorns on old." 



This plant is represented by two pinnae 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 T25 cm. and overlap ; the middle pinnules are 

 horizontal, tlie lower are deflexed.
