should be retained. An exact synonym is Pavetta manillensis 
Walp. (1843). The species is of local occurrence at low and 
medium altitudes in central and northern Luzon.

3, 1 (1877) 76, t. 21. 
Blanco seems to have correctly interpreted the Linnean spe- 
cies, which occurs in the Philippines only as an introduced and 
cultivated plant. From its native name santan (corruption of 
Santa Ana) it is probable that it was introduced after the arrival 
of the Spaniards. This red-flowered form is commonly desig- 
nated as santdn puld, i. e., red santan, in distinction from the - 
white-flowered species I. finlaysoniana Wall. which is called 
santdn puti, i. e., white santan. ;

Taligalea umbellata Blanco FI. Filip. ed. 2 (1845) 387 (sp. nov.); ed. 3, 
2 (1878) 66=IXORA CUMINGIANA Vid. 
This species is common and widely distributed in the northern 
and central Philippines, occurring in thickets and in forests at 
low and medium altitudes. Bianco’s specific name is invalidated 
in Izxora by I. umbellata Valeton. By Fernandez-Villar it was 
reduced to Ixora macrophylla Bartl., but Blanco’s description does 
not apply to Bartling’s species while, moreover, I. macrophylla 
Bartl. was described by Blanco as Ixora arborea. 
Illustrative specimen from Rizal Province, Luzon, November, 
1915 (Merrill: Species Blancoanae No. 954). 
Ixora arborea Blanco Fl. Filip. (1837) 61 (sp. nov.) ; ed. 2 (1845) 42; ed. 
3, 1 (1877) 78, non Roxb.=IXORA MACROPHYLLA Bartl. 
Blanco’s species was reduced by Fernandez-Villar to Ixora 
stricta Roxb., but although the description is short and imper- 
fect it manifestly does not agree with Roxburgh’s species. So 
far as the description goes it is in entire agreement with Ixora 
macrophylla Bartl., a species based on Philippine material and 
one of wide distribution in the forests of the Archipelago at 
low and medium altitudes.
