5, An absence of species with acute anthers, as in Burma and 
the Malayan Archipelago, in each of which only one has 
been collected out of 70 and 50 species respectively ; in 
China proper, on the other hand, nearly one-fourth of the 
known species have acute anthers. 
6. The solitary species with opposite or whorled leaves in Indo- 
China conforms to the condition of the genus in Burma 
and the Malayan Archipelago, in each of which areas only 
one of a large number of species shows this character ; on 
the other hand, of the twelve Malayan Peninsular species 
four have opposite or whorled leaves, conforming with the 
hinese area where species with this character are as 
numerous as those with acute anthers. 
To conclude, the species of the Malayan Peninsula conform with 
those of Indo-China in all but one character, the sixth, and partly 
with that, and may be regarded as together indicating one and the 
same area, most nearly allied to the Burmese and very different from 
the Chinese. 
How far these conclusions will prove aught but crude indications 
remains to be seen when fuller materials for their scrutiny shall be 
forthcoming.
