vatis 2 ad 3 mm longis instructis; foliis chartaceis, ovatis, 7 
ad 9 cm longis, 4.5 ad 6 em latis, breviter acuminatis, basi ro- 
tundatis, serratis, supra olivaceis, scabridis, densissime puncti- 
culatis, parce pubescentibus, subtus dense cinereo-pubescentibus,

Ng Chi Leng, McClure 8501, December, 1921. In forested 
ravines, altitude 900 meters. 
A species allied to Debregeasia squamata King of the Malay 
_ Peninsula, and like the latter characterized by the numerous 2 to 
3 mm long, curved, spinelike spicules which are apparently soft 
when fresh. The spicules are not flattened however as in King’s 
species, while the leaves are smaller.
