colour, which sometimes turns scarlet. This group is connected with the true Mussendas 
by M. coccinea, which has no enlarged calyx-lobe and scarlet flowers, but otherwise 
comes very near to them, particularly in the leaves and fruit. These species can hardly be 
separated from Mussenda, but they might be made conveniently into a separate section, 
for which I propose the name Asemanthia. 
The leaves of M. coccinea, as it is represented by no. 1357 of Haviland, differ at the 
first glance considerably from the fruiting specimen, 1356, and from Low’s specimen. 
But there is no doubt about the identity of the latter and 1356, and as the inflorescence 
and the flowers of Low’s plant and of no. 1357 entirely agree, I have no doubt that 
they all belong to one species, especially as one of the leaves of no. 1357 has a much 
shorter petiole and is comparatively broader, thus approaching the shape of the leaves in 
Low’s plant, and as the nervation follows the same type, though the nerves are more 
distant in accordance with the lengthened shape of the blade. 
Burck (Ann. du Jard. Buit. iii. 108-112) has shown that at least several of the 
Mussendas are dicecious. It is rather difficult to check his investigations on dry 
material. The structure of the corolla is certainly of the male type, and the anthers are 
polliniferous in the two flowering specimens in my hands; further, the style is very short 
and in all probability imperfect. The ovary is apparently fertile, but the numerous ovules 
did not give me the impression that they are so. The specimen of JM. mutabilis figured 
in Hook. Ic. Pl. t. 1718 is male also; but the specimen of the new species, collected by 
Lobb in Sarawak, seems to be female. The corolla tube is a little widened above, but 
gradually and much less than in the male flowers of M. coccinea and M. mutabilis, and 
the anthers are indehiscent ; the corolla tube, however, is golden papillose down to their 
insertion, as one would expect for male flowers. On the other hand, the style reaches to 
the tips of the anthers and divides into two subulate branches which slightly surpass the 
mouth of the corolla.
