INTRODUCTION. 
D. Kunsileri) flourish on Mount Ophir and on the Gunong Tambang Batak, between 
500 to 1,500 metres above the sea. 
It seems that those species which show a predilection for high mountains have 
a tendency to shorten their stems and to lose their scandent character. 
Generic differences between Daemonorops and Calamus. 
DAEMONOROPS, 
Leaf-sheaths—Never flagelliferous. 
Ocrea—Always very short; only in D. ursinus it 
is prolonged into two long appendages. 
Leaves—The upper always more or less cirriferous. 
Leaflets—Always narrow sad acuminate; never 
rhomboidal nor 
Spathes— After di ahi o open, wee eymbiform 
or flat, deciduous ; never armed wi 
Spadices—Form a panicle, mostly a very short one; 
no thorns on the axial parts.

Involucrophorum—pedicelliform truncate, and almost

Spikelets— 3 almost always have perfectly bifari-

Involucrophorum—]s either infundibular or cupular. 
Involucre—Cupular.

D. longispathus and D. ruptilis are, perhaps, the species which approach nearest to Calamus.
