New Caledonia to Polynesia. 
The specimen agrees very closely with Balansa 393 from New Caledonia, 
differing in a few slight characters, such as its calyces being hirsute rather 
than velutinous. In both the seeds are quite wingless. The type of 
Melochia odorata was from the Island of Tanna, near New Caledonia. 
MELOCHIA HIRSUTISSIMA sp. nov. § Visenia. 
Frutex, omnibus partibus dense hirsutis; foliis cordato-ovatis, 
coriaceis, usque ad 8 cm longis, acuminatis, basi late rotundatis 
cordatisque, margine dentato-serratis ; floribus 8 ad 9 mm longis, 
capsulis ovoideis, acuminatis, non sulcatis, hirsutis, seminibus 
anguste obovoideis, obscure 3-angulatis, angulis rotundatis, haud 
alatis. 
A shrub, size not indicated, densely hirsute with long, pale or 
brownish, more or less shining hairs. Branches terete, very 
dark-brown, older ones glabrous or nearly so, the younger 
branchlets very densely hirsute, pale-brownish or grayish-brown. 
Leaves cordate-ovate, coriaceous, 5 to 8 cm long, 3 to 5.5 cm 
wide, base broadly rounded, rather shallowly cordate or sub- 
truncate, apex shortly acuminate or merely acute, margins rather 
finely serrate-dentate, both surfaces of the same color, uniformly 
hirsute with mostly simple, spreading, rather pale, more or less 
shining hairs which are for the most part on the midrib, nerves, 
and reticulations, the upper surface in young leaves with inter- 
mixed, softer, stellate hairs; basal nerves 3, the lateral 
nerves above the base usually 4 on each side of the midrib; pe-
