(U. S. Expl, Exped.). Also from Aneitum and Eromanga (M‘Gillivray !). 
This species is certainly different from D istingui t once by the 
i ny . pentaphylla, Blume, and may be distinguished at once DY 
greater number of the divisions of the frond, the be a ternate lower ak and the obvious veins. We 
er see no reason for separating the two forms described by Brackenridge as distinct. A large series 
collected by M‘Gillivray shows that the characters on which he depends are not constant.
