Genus ADONIDIA Beceari 
ADONIDIA MERRILLII Bece. (Plate II, III). BUNGA DE CHINA. 
Local names: Bunga de China, binga de Jolé (Span.-Fil.) ; oring-oring 
(Tagbanua). 
This species is the only representative of the genus and is 
known only from the Philippines. In Manila it is extensively 
cultivated for ornamental purposes. The species was originally 
described from material taken from cultivated specimens in Ma- 
nila, its origin being unknown. Since then its original home 
has been located, as it occurs in abundance on limestone forma- 
tions in Palawan and the Calamianes Islands (Coron). In 
habit this palm resembles the betel palm, but it is not so tall, 
and its leaves are much more strongly arched. It reaches a 
height of 8 meters and a diameter of 10 to 15 centimeters. 
The leaves are about 2 meters long with 40 to 50 pairs of leaf- 
lets. Its inflorescence, too, is quite different from that of the 
betel palm: The bright-crimson fruits, contrasting with the 
whitish fruit-stalks and sheaths, are very ornamental. The 
fruits are said sometimes to be used as a substitute for the betel 
nut, in preparing buyo (fruit of Areca catechu, leaves of Piper 
betle, and lime) for chewing. The name “Bunga de Jolo,”’ 
which is very seldom used, may indicate the true origin of the
