ultimate branchlets similar in appearance but more or less com- 

 pressed at the nodes. Leaves firmly chartaceous to subcoria- 

 ceous, elliptic to broadly elliptic-oblong, 15 to 23 cm long, 7 to 

 10 cm wide, base acute, apex obtuse to shortly and broadly blunt- 

 acuminate, pale-olivaceous and shining when dry ; primary lateral 

 nerves 12 to 15 on each side of the midrib, irregular, distinct, 

 anastomosing, the secondary nerves also rather prominent, retic- 

 ulations lax; petioles stout, up to 1 cm in length. Inflorescence 

 terminal, of few, fascicled, peduncled, rather many-flowered 

 heads, the peduncles usually two or three at the apex of each 

 branchlet, stout, up to 1 cm in length, each bearing 20 or more 

 sessile flowers, the involucral bracts lanceolate to oblong, some- 

 what acuminate, 9 to 13 cm long, somewhat puberulent toward 

 the apex. Flowers white, about 2.5 cm long, slender, the tube 

 glabrous, the lobes rather densely puberulent inside. Ovary 

 narrowly ovoid, rather densely appressed-hirsute in the upper 

 part. Fruit broadly ovoid, very slightly compressed, subacute, 

 2-celled, about 12 mm long and wide, glabrous. 



Amboina, Paso and Batoe merah River, Rel. Robins. 1802, September, 

 1913, in thickets and along the river, altitude 5 to 60 meters. 



The genus Phaleria seems to be well developed in the Malay Archipelago, 

 but from the material available for comparison and the published descrip- 

 tions, I cannot definitely refer this Amboina plant to any previously de- 

 scribed species.

The specimen presents imperfect flowers and no fruits, so that its 

 identity with Korthal's species is somewhat doubtful. The type of the 

 species was from Borneo, and the Amboina specimen agrees well with the
