This was reduced by Fernandez-Villar to Melodorum fulgens 
Hook. f. & Th., a manifestly wrong reduction, for Blanco’s de- 
scription does not at all apply to the latter species. The present ° 
interpretation of the species is undoubtedly correct. 
Illustrative specimen from San José, Batangas Province, Lu- 
zon, February, 1915, there known as amuyong (Merrill: Species 
Blancoanae No. 803). 
MITREPHORA Blume

MITREPHORA LANOTAN (Blanco) Merr. in Govt. Lab. Publ. 
(Philip.) 35 (1906) 71. 
Blanco’s species was erroneously reduced by Fernandez-Villar 
to Goniothalamus giganteus Hook. f. & Th., a species that does 
not extend to the Philippines and one to which Blanco’s descrip- 
tion does not at all apply. Im making the original transfer to 
Mitrephora I erroneously included, as a synonym, Mitrephora fer- 
ruginea Merr.=M. merrillii C. B. Rob.=Griffithianthus merrillit 
W. H. Br., and my description in part applies to the latter 
species. The plant interpreted as Mitrephora lanotan agrees 
perfectly with Blanco’s description, is common in the regions 
from which Blanco secured most of his material, and is also 
known to the natives as lanotan, a name also applied to a number 
of other annonaceous trees. at 
Illustrative specimen from Bataan Province, Luzon, June, 
1915, comm. H. Borromeo, there known as lanotan (Merrill: 
Species Blancoanae No. 940). 
XYLOPIA Linnaeus 
Unona dehiscens Blanco Fl. Filip. (1837) 466 (sp. nov.); ed. 2 (1845) 
325 (dehincens); ed. 3, 2 (1878) 238=XYLOPIA DEHISCENS 
_ (Blanco) Merr. (Xylopia blancoi Vid.) . 
Fernandez-Villar erroneously reduced Blanco’s species to 
Anaxagorea luzonensis A. Gray, to which Blanco’s description 
does not at allapply. Vidal redescribed it from actual specimens 
as Xylopia blancoi, citing Blanco’s species as a synonym. Blan- 
co’s description is very poor and imperfect, but his species ap- 
parently belongs here. It is found in various parts of Luzon 
and in the Visayan Islands.
