5. Rotan Tanah. 
Abundant and widely distributed, occurring 
under a wide range of conditions. The name Rotan 
Tanah is given because this rattan frequently creeps 
along on the ground for some distance before climb- 
ing. As many as 30 stems are borne from one clump 
and they reach a length of 150 feet. Cane a pale 
yellow. Length of internode up to 25 inches ; 
diameter up to 0.6 inch. A very durable cane. 
Seldom used whole except plaited into a three strand 
buffalo rope. Used split for a variety of purposes, 
but does not split finely. Used for tying thatch, 
basket making, etc. When collected for export it 
is washed in sand and mixed with other rattans 
under the name of Rotan Barang. 
6. Rotan Batu. 
Calamus insignis Griff. ? 
A fairly abundant and well distributed rattan on 
hill slopes and on the well drained banks of rivers. 
Stems 20 to 30 per plant, up to about 200 feet in 
length. Cane plain pale yellow. Said to be very 
strong and probably our most durable rattan. 
Length of joint 7 to 13 inches; diameter about 0.3 
inch. The cane is used whole, split, and “ drawn,' ” 
and is considered superior to Rotan Sega in every 
way except in the matter of natural polish. Used 
whole for buffalo ropes, securing beams, etc. When 
“ drawn ” it is used for furniture and basket making. 
Split, it is used for tying thatch, fishing traps, bird 
snares, furniture and mats. This rattan is in great 
demand. It is sold unmixed, after being washed in 
sand. It is probable that other species with similar 
stems are also known by this name.
