Java and Celebes to New Guinea. 



I), canmrcforniis Rolfe most closely resembles />. grandis Ridl. in its size and 

 fruit, but is easily distinguished by its larger flowers, its stamen with a long- 

 linear lateral lobe, its silky pubescent ovary, and its fruit covered tbinly with 

 bairs. Tbe seed is more oblong and wrinkled. 



K. Schumann in Pflanzenreich 1 1 lias made a sad mixup in this simple genus. 

 At present only four species are known, as follows: 



I), arundastrum Lour., a dwarf plant with larger flowers than the others, and 

 a turbinate 3-seeded fruit. It is abundant on river banks from Siam, Cochinchina 

 and India to the Malay Peninsula. 



1). parviftora Ridl., a native of the Malay Peninsula. 



I>. grandis Ridl., a very large plant, with globose, glabrous, 1-seeded fruits and 

 smaller flowers, ranging from Siam to Singapore. 



I), cannacformis Rolfe, ranging from Java to New Guinea and the Eastern 

 Archipelago, an often tall plant with larger flowers than D. grandis, and 1-seeded 

 hairy fruit. 



17. PHACELOPHRYNIUM K. Schumann. 



Tufted herbfl with long-petioled leaves. Inflorescence a dense or 

 interrupted panicle of spikes, with distichous bracts, from a leaf-petiole. 

 Flowers in pairs or threes, pedicellate. Bractooles two to each flower. 

 Sepals linear or subovate. Corolla-tube short or very abort, the lobes 

 oblong. Lip with an oblique villous ridge. Petaloid stamen spathu- 

 late or ovate, cucullate, short. Ovary 3-celled. Capsule 3-angled, 3-, 

 rarely 2-seeded. Seed 3-angled. 



Species 7, Nicobar Islands, the Malay Peninsula and Archipelago. 



1. P. interruptum K. Sebum, in Pflanzenreich 11 (1902) 121. 



Stems 2 to 3 m tall. Leaves lanceolate or elliptic-lanceolate, 30 cm 

 long, 9 to 11 cm wide, glabrous; petiole 3 to 5 cm long; sheath glabrous. 

 Inflorescences usually three, interruptedly panieled, 12 to 20 cm long. 

 the internodes about 8 cm long, the racemes fascicled, fairly dense, 

 four together, 5 cm long. Primary bracts oblong-lanceolate or ovate, 

 4 cm long or less. Floral bracts about 8, oblong, obtuse, fleshy, 1 cm 

 long. Flowers yellow, in pairs on pedicels 5 mm long. Ovary triquet-
