300 SPECIES BLANCOANAE 
PLUMBAGINACEAE 
PLUMBAGO Linnaeus 
Plumbago viscosa Blanco Fl. Filip. (1837) 78 (sp. nov.); ed. 2 (1845) 58; 
ed. 3, 1 (1877) 111=PLUMBAGO ZEYLANICA Linn. 
The species is of wide distribution in the settled areas of 
the Philippines at low and medium altitudes, but is of rather 
local occurrence; it is undoubtedly an introduced plant in the 
Archipelago, although now thoroughly naturalized. 
Illustrative specimen from Balayan, Batangas Province, Lu- 
zon, August, 1914 (Merrill: Species Blancoanae No. 479). 
SAPOTACEAE 
BASSIA Linnaeus 
Azaola betis Blanco Fl. Filip. (1837) 402 (gen. et sp. nov.); ed. 2 (1845) 
281; ed. 8, 2 (1878) 157=BASSIA BETIS (Blanco) Merr. in Philip. 
Journ. Sci. 10 (1915) Bot. 56 (Payena betis F.-Vill., Illipe betis Merr.). 
This endemic species is of wide distribution in the Philippines, 
occurring in the primeval forest, yielding a very valuable build- 
ing timber, and universally known as betis, which is also the 
commercial name of its timber. 
Illustrative specimen from Cavite Province, Luzon, April, 
1915, there known as betis (Merrill: Species Blancoanae No. 
956). 
PALAQUIUM Blanco 
Palaquium latifolium Blanco FI. Filip. (1837) 404 (sp. nov.); ed. 2 (1845) 
282; ed. 3, 2 (1878) 159=PALAQUIUM PHILIPPENSE (Perr.) C. 
B. Rob. in Philip. Journ. Sci. 3 (1908) Bot. 304. 
Palaquium oleiferum Blanco op. cit. 405 (sp. nov.).; 283; 160=PALAQUIUM 
PHILIPPENSE (Perr.) C. B. Rob. 
From Blanco’s descriptions Palaquium latifolium and P. oleife- 
rum cannot be distinguished, the description of the former being 
fairly complete, and that of the latter much shorter, incomplete, — 
and of the leaves and fruits only. The common Tagalog names 
for the species are palac-palac (from whence the generic name) 
and alacac, while the Ilocano name, as it appears on our speci- 
mens, is araca and dapagan; Blanco cites the Ilocano name 
daracan. for his Palaquium oleiferum. The species is common 
and widely distributed in Luzon and Mindoro, at low and medium 
altitudes, generally growing in the primeval forest. Synonyms oe 
appear to be Chrysophyllum macrophyllum Desf. and C. grandi- 
folium Steud., but the earliest valid specific name is that sup- 
plied by Chrysophyllum philippense Perr. in Mém. Soc. Linn, 
Paris 3 (1824) 109. : ee
