Other Uses

Basketry  Furniture  String  Wood

Other uses rating: High (4/5). Other Uses The stems are used in basketry, as a tying material etc[ 454 ]. Although they can be many metres long, they only attain the thickness of a pencil[ 454 ]. In addition to their use in basket making, the stems are used for making the bottoms of chairs, for which purpose they are first split into long thin strips to render them elastic and pliable[ 454 ]. When twisted, they can be used as very strong ropes for towing purposes[ 454 ]. Finally, the thin strips cut from this cane are used for making the frames for hats used by some of the working classes in Sri Lanka[ 454 ].

Cultivation details

Most species in this genus are more or less vigorous climbing plants in rainforests. In general, they are likely to grow best with their roots in the shade but with their stems able to grow up to the light. They are also likely to grow best in a humus-rich soil[ K ]. A dioecious species, both male and female forms need to be grown if fruit and seed are required.
