250 MR. J. G. BAKER ON THE 
the branch is terete; but it passes at the top into an oblanceolate 
thick rigid phylloclade half a foot long, 3-3 in. broad, narrowed 
gradually from the middle to the base, with very fine anastomo- 
sing vertical veins, the same on both sides, and margined with 
teeth about 3 in. apart, indented on the anterior side only. From 
the sides of primary phylloclades branch out others that are 
quite similar in shape and texture; and sometimes these are 
branched again. Dr. Meller gathered it in 1862 in dense woods 
near Mbatomanga, sixty miles south of the capital; and now 
Mr. Baron has obtained it (1631) from woods between Tankay 
and the east coast. The plant is so interesting, from both a sys- 
tematic and a geographical point of view, that it is to be hoped 
perfect specimens may soon be obtained. The wood of the tree, 
Mr. Baron says, is extremely hard. 
CEPHALOPHYTON PARKERI, Hook. fil. 
This is a curious new genus of Balanophoree with the habit of 
a compound Spheria (say Hypoxylon multiforme). It was 
brought home by Dr. Parker, and is used in the island medici- 
nally. As the specimens are few in number and do not show 
the male flowers, Dr. Parker has sent for fuller material; and 
when this arrives Sir J. D. Hooker will characterize the genus.
