Arecaceae. PALM FAMILY, 
Among the palms growing in Guam are Areca catheen, Saquerus pinnatus, Cocos

Argyreia tiliaefolia. LINDEN-LEAVED MORNING-GLORY. 
‘amily Convolvulaceae. 
Loca NAMrEs.—Alilag, Abubo (Guam); Bululacao (Philippines); Pilikai 
(Hawaii). 
A stout, climbing morning-glory with pale purple flowers, woody stem, and cor- 
date or reniform leaves. Corolla large, funnel-shaped; style single, bearing 2 globose 
stigmas; fruit a leathery capsule, not bursting open like that of an Ipomoea; sepals 
coriaceous, silky-pubescent; young shoots canescent; leaves glabrate with age, 6 to 
7.6 em, long and as much or more in breadth. 
A common plant in the thickets of Guam. Unlike other members of its family it 
does not bloom continuously, but flowers in the month of November. The flowers 
do not wither like many morning-glories, but remain open all day. The natives call 
them “abubo,’”’ a different name from that applied to the plant itself. The children 
string them on strings and sticks, and are very fond of them as ornaments. The 
species is found in India and the Philippines. It has been introduced into the 
Hawaiian Islands, where it has escaped from cultivation and established itself.
