SANTALACES. 
Exocarpus sp. ? 
Arfak Mts., Koebré ridge, common in forest undergrowth from 8000- 
8500’. Veg. 5617. 
A leafless parasite, with dark green, rigid, flattened, much branched 
shoots, about 1m. high. The cladodes are 5 mm. broad, showing swollen 
round scars alternately up the nodes, on which the flowers are evidently 
borne in fascicles. I am indebted to Mr. 8. Moore for this determination, 
but, as he points out, in the absence of flowers or fruit the genus must 
remain uncertain.
