Pale, PHILIPPINE PALMS 
The palm is decidedly ornamental and is worthy of more ex- 
tended cultivation for this reason. 
Heterospathe negrosensis is known in Visayan as saltai and 
Heterospathe sibuyanensis as bilis. 
Genus KORTHALSIA Blume 
This genus is represented in the Philippines by four known 
species. It is closely allied to Calamus and Daemonorops, but 
is readily distinguishable by its inflorescence and its broad, 
wedge-shaped leaflets which are usually whitish beneath. Like 
Calamus and Daemonorops, our species of Korthalsia are climb- 
ing palms. They are invariably sylvan. The stems are of in- 
definite length and of the same diameter throughout. These 
palms are of some biological interest from the fact that the 
more or less inflated sheaths are always inhabited by colonies 
of ants. In general the stems of Korthalsia may be used for 
the same purposes as those of Daemonorops and Calamus, but 
no special use is recorded for any of the Philippine forms.

Genus LICUALA Thunberg 
LICUALA SPINOSA Wurmb. (Plate XXXIII). BALATBAT. 
Local names: Balatbdt (Bisaya); ugsdng (Balabac, Palawan, Moro). 
This is the only representative of the genus found in the 
Philippines and no special economic uses are recorded for it. 
It is found near the sea in Palawan and in the Calamianes Is- 
lands, sometimes growing immediately back of the mangrove and 
within the influence of salt water, sometimes on banks and in 
ravines near the sea. The palm is of small size, has fan-shaped 
leaves, and is decidedly ornamental. It is now being grown 
considerably in Manila for ornamental purposes.
