 DJSTEIB. Malay Islands. 



A tree, 30-40 ft., glabrous except the inflorescence ; branches stout. Leaves 

 610 in., oblong-ovate or oblong, acute or acuminate ; petiole f-lg- in. Floivers iu 

 dense corymbose terminal cymes. Male flower in. long, tubular- campanulate, pedi- 

 celled, 5-toothed ; stamens 8. Female flower much smaller ; stigma penicellate. Fruit 

 .}- f in. long, long-pedicelled. It is very doubtful what name this should bear ; it may 

 probably be identified with P. inermis, Forst., of the Pacific Islands.

ANDAMAN ISLANDS ; forests along the coast, Kurz. DISTRIB. Malay Islands. 



A tree, 30-50 ft., glabrous except the puberulous shoots. Leaves 1^-1 ft. glossy ; 

 petiole ^-1 in. Flowers small, cymose or umbellate ; peduncles sparingly tomentose 

 or glabrescent. Perianth nearly glabrous. Fruit 1 in. or less, glabrous. Kurz has 

 referred this to Seemann's P. umbellifera, which Bentharn affirms (Fl. Austral. 

 v. 281) to be Blume's P. excelsa. I have seen only leaf and fruit, the rest of the 

 above description being from Kurz.
