The new species of Hua have not been seen ; but they are stated to be founded 
solely on the hairiness of the midrib of the under surface of the leaves, and on the 
degree of curvature and divarication of the cells of the anther of the intermediate 
stamen. The large series of J. thyrsiflora in Kew shows that these characters cannot 
be employed to found species upon.

The localities in Lower Guinea hang on the correct reduction of P. congolana, 
Hua, which has not been seen, 
It appears from an observation of Hua that his P. prionostachys had a hairy 
ovary, and was therefore not the present species which has the ovary quite glabrous 
as in P. thyrsiflora, to which it is very closely allied.

Originally described from a cultivated plant. This appears to have been one of 
the hemiscapose group ; the leaves only are described by Masters; and his description 
‘may do for any one of the first 3 species above.
