188 USEFUL PLANTS OF GUAM. 



Arecaceae. Palm family. 



Among the palms growing in Guam are Areca cathecu, Saguerus pinnatus, Cocos 

 nudfera, Nypa frulicans, the recently introduced Coelpcoccus amicarum and Phoenix 

 dactylifera, and a small, slender-stemmed palm with pinnate leaves called "palma 

 brava. ' ' 



Arenga saceharifera. Same as Saguerus pinnatus. 



Argyreia tiliaefolia. Linden-leaved morning-glory. 



Family Convolvulaceae. 



Local names. — Alalag, 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 

 7.5 cm. 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.
