Physical properties, fibre morphology and chemical constituents of five Malaysian canes, viz. Calamus manan (rotan manau), C.palustris var. malaccensis (rotan manau langkawi), C. scipionum (rotan semambu), Korthalsia rigida (rotan dahan) and Plectomiopsis griffithii (rotan mantang gajah), are reported. There is a wide variation in the fibre dimensions as well as the physical properties of all the species studied. The fibres are relatively short (1.34-2.17 mm) and thick-walled. The oven-dry density ranges between 0.33 and 0.61 g/cubic m and tends to decrease from the basal towards the top portion. With the exception of the holocellulose content, the chemical constituents differs significantly in content with species and height. The higher contents of water and alkali solubles of the rattans observed in the study indicate that proper selection, preparation and treatment should be considered in order to prolong their service lives.
