more like Wallich’s O. angustifolia. It is probable that 
the three are but varieties of one species. 
Melastoma macrocarpon Don. DC. Prod. 3. 145 ?—speci-

Melastoma calycina (sp. n.; ramulis petiolis nervisque

non Linn.—A large-flowered species, much handsomer than 
M. Malabathrica, which does not appear to be indigenous to 
any part of China. Mr. Hinds's specimen is not in flower, 
but is evidently the same plant as one from Mr. Vachell, 
with very good flowers, which I have here described. The 
M. septemnervia of Loureiro, from Canton, may possibly be 
the M. macrocarpon, Don; but is certainly neither M. Mala- 
bathrica Linn., nor yet my M. calycina.

I have referred this plant to Allomorphia, Blume, notwith- 
standing the absence of the 4 sterile stamina, as several of the 
allied genera are made to include both aplostemonous and 
diplostemonous species. The most important character 
consists in the ovary, viais included in the bottom of the
