292 SPECIES BLANCOANAE 
of the forms have been described under other specific names. 
Blanco’s Melastoma asperum—M. obvolutum Blanco, non Jack, 
represents what I take to be fairly typical Melastoma polyan- 
thum Blume, as I understand Blume’s species. It is hardly 
Melastoma malabathricum Linn. to which Fernandez-Villar 
reduced it. Blanco’s material was from Angat, but his descrip- 
tion, as to the size of the leaves, applies, in our material, only 
to the smaller leaves. Fernandez-Villar reduced Melastoma 
malabathricum Blanco to M. sanguineum Sims. I can now see 
no reason for considering it other than M. polyanthum Blume.

Melastoma tamonea Blanco Fl. Filip. (1837) 367, non Sm.—Melastoma 
dodecandrum Blanco op. cit. ed. 2 (1845) 258; ed. 3, 2 (1878) 116, non 
Roxb., nec aliorum=MELASTOMA HOMOSTEGIUM Naud. 
Fernandez-Villar reduced this to Melastoma imbricatum Wall., 
a species that does not extend to the Philippines, while I pre- 
viously expressed the opinion that it was certainly the same as 
Melastoma polyanthum Blume. However, Blanco describes his 
species as having 6-merous flowers, his specimens being from 
Panay. Specimens of Melastoma having 6-merous flowers con- 
form with Melastoma homostegium Naud., the type of which is 
from the Philippines, Cuming 927, and has 6-merous flowers. 
’ Cogniaux reduced Melastoma homostegium Naud. to Melastoma 
obvolutum Jack. The type of Jack’s species is not extant, but 
Mr. A. W. Hill informs me that all the material so-named in 
the Kew Herbarium, except my No. 800, which matches Cuming 
927, and a specimen from Borneo, has 5-merous flowers. 
OSBECKIA Linnaeus 
Osbeckia multiflora Blanco Fl. Filip. (1837) 293, non Smith—Osbeckia 
ee sinensis Blanco ed. 2 (1845) 205; ed. 3, 2 (1878) 20, t. 421=— 
OSBECKIA CHINENSIS Linn. | 
This species is of very wide distribution in the Philippines. — 
Blanco’s description applies to a small, unbranched form. ee
