CANANGIUM Baillon 
Unona odoratissima Blanco Fl. Filip. (1837) 467 (sp. nov.); ed. 2 (1845) 
325; ed. 3, 2 (1878) 239, t. 221 —CANANGIUM ODORATUM (Lam.) 
Baill. (Cananga odorata Hook. f. & Th.). 
Unona ossea Blanco FI. Filip. (1837) 467 (sp. nov.) =Uvaria ossea Blanco 
op. cit. ed. 2 (1845) 322 (comb. nov.) ; ed. 3, 2 (1878) 233 =CANAN- 
GIUM ODORATUM (Lam.) Baill. (Cananga odorata Hook. f. & Th.). 
The identity of Unona odoratissima Blanco is unmistakable, 
as it is the common and widely distributed ilang-ilang tree. 
Unona ossea Blanco—Uvaria ossea Blanco was reduced by Fer- 
nandez-Villar to Unona discolor Vahl, which I formerly con- 
sidered to be the correct disposition of it. However, Vahl’s 
species scarcely occurs in the regions from which Blanco secured 
his material, and moreover a comparison of his description with 
specimens of Vahl’s species shows that Unona ossea Blanco 
cannot possibly be the same as Unona discolor. Blanco com- 
pares Unona ossea with Unona odoratissima, as identical in 
floral characters with the latter, stating that except in its fra- 
grant fruit it could not be distinguished from ilang-ilang. There 
is no doubt whatever that Unona ossea Blanco is merely a slight 
variant of the common and widely distributed Canangium 
odoratum Baill. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
January, 1914, there known as ilang-ilang (Merrill: Species 
Blancoanae No. 466). Te 
POLYALTHIA Blume 
Unona cabog Blanco FI. Filip. (1837) 466 (sp. nov.)=Unona odorata 
Blanco op. cit. ed. 2 (1845) 325 (nom. nov.); ed. 3, 2 (1878) 237, 
non Dunal=POLYALTHIA sp. 
Fernandez-Villar reduced this to Unona desmos Dunal, which | 
I formerly thought might be the correct disposition of:it At 
cannot, however, be Dunal’s species. The description applies 
unmistakably to Polyalthia, but beyond this I can make no 
suggestion as to what species was intended by Blanco’s very 
imperfect description. 
PHAEANTHUS Hooker f. & Thomson 
Uvaria tripetala Blanco Fl. Filip. (1887) 465, non Roxb.=Unona. tripe- :

of the Philippines at low and medium altitudes. jariei 39
