Our specimens are only in bud, and may prove a distinct species. In one instance the peduncle is terminal 

 and not jointed, so that it perhaps ought to be described as terminal on a short axillary branch, which is 

 furnished about the middle with two small opposite deciduous leaves.

Had. Elizabeth Island. — " This," Mi-. Collie observes, " forms a tree or shrub, the trunk of which is 

 very slender, about two inches (feet?) in circumference, and twenty feet high. The wood is whitish, 

 very hard, and close-grained, with a reddish inner bark." It seems to approach the Cephaelis speciosa of 

 Sprengel, (from Tahiti,) but the leaves are not " oblongo-lanceolate."
