lobes at the lower part) ; terminal lobes with g or 10 acute 

 teeth about an inch long and half an inch wide at the base; 

 whole blade about 2 feet long and 8 inches across in the widest 

 part; terminal lobes 6 inches long; nerves and midrib very 

 prominent on both surfaces, above dark green, beneath 

 glaucescent. Spathes boat-shaped, about 6 inches long. 

 Spadix 2-3 branched; peduncle 3 inches long; branches 4 

 inches wide, densely covered with reddish wool. Flowers 

 spirally arranged, remote. Male flower ^ inch long; petals 

 triangular, acuminate. Female ^ inch long, subglobose. 

 Sepals orbicular, striate, glabrous. Fruit (not quite ripe) 

 olive-shaped, half an inch long. Seed nearly as long, base 

 blunt, ribbed externally. Albumen ruminate, with rather 

 large intrusions running nearly to the centre. 



This palm is the only one, except two Calameae, occurring 

 on the Padang. It is abundant in all the wet woods from 

 below the Gully to nearly 6,000 feet elevation. It constantly 

 emits lateral buds from the stems. I had a great difficulty in 

 finding any male flowers, till by cutting into a leaf-sheath that 

 appeared to be swollen I found a much decomposed spathe 

 with some rotten flowers on the spadix, and the female flowers, 

 though not }et free from the leaf-sheath, were fairly developed. 

 I suspect that this palm is usually self-tertilized before the 

 spathe opens. Spadices with female flowers and young fruit 

 were abundant. The rachis of the spadix is red and the fruits 

 apparently black when ripe.
