The affinities of Dendrobangia are clearly with the Icacinaceae. 
Of this Dr. Engler makes three sub-families, to one of which, the 
Icacinoideae, with 1-celled ovary, Dendrobangia pertains. Of the 
four tribes of this sub-family, three comprise only climbing plants 
and their floral characters exclude the genus under consideration, 
which is clearly a member of the tribe Icacineae. In this tribe Dr.. 
Engler recognizes 26 genera, all but 7 of them having the calyx 
gamosepalous, thus excluding Dendrobangia, the sepals of which 
are barely coherent at the base. Of these 7 genera, Vi//aresia is 
the only one known to have representatives in America. Villaresta 
has the petals imbricate, while in Dendyobangia they are perfectly 
valvate. From the six foreign genera the plant is distinguished 
as follows: Cassinopsis, of Africa, has the stamens opposite the 
petals. Leptaulus, of Africa, has a slender infundibular corolla. 
Alsodeiopsis, of Africa, has the filaments free from the corolla-tube. 
Platea, of Polynesia, is polygamous, and has the stamens free. 
Sarcanthidion, of New Caledonia, has the petals imbricate, like 
Villaresia. It may be said that, in addition to the characters given, 
none of the above have apical appendages to the petals, while this 
is a most important character of Dendrobangia. Although the 
remaining genus, Chariessa, of New South Wales, has such append- 
ages, they are very different from those of Dendrobangia. The 
petals of Chariessa, moreover, are distinct, except at the very base, 
and its stamens are free. The characters of filament and anther 
and the absence of a style would also certainly exclude Dendro- 
bangia from that genus. It appears, therefore, that the plant is 
strikingly distinct from any other genus, and that it combines in a 
remarkable manner the characters of the associated genera. It 
agrees with Vi//aresia in the general ovary-characters, with A/so- 
deiopsis and Leptaulus in the partially gamopetalous corolla, with 
Leptaulus in the adnate filaments, with P/a¢ea in the sessile stigma, 
and with Chariessa in having apical petal-appendages. 
In the description of the plant already published, a number Of 
points were misinterpreted or overlooked, and that description 
should be amended as follows: The sepals are barely coherent at 
the base, which fact, taken in connection with its general charac- 
ters, must place it in the first section, described as having a chori- 
sepalous calyx. The term ‘corolla-lobes” and not “ petals,” oe
