General Information

Korthalsia jala is a spiny, evergreen, climbing palm producing a cluster of robust stems that climb into the surrounding trees. The stems can reach lengths of 60 metres with a diameter of 60mm and internodes around 20cm long - they are unbranched in their lower parts, then orm a number of branches in the canopy where they can form considerable entanglements. The stem is very slender towards the base, but new growth gradually thickens, reaching its greatest diameter at the upper end at the time of flowering[

Many species in this genus have a close association with ants that make their nests within swollen structures in the leaf sheaths known as ocreas. The ant-rattan relationship also seems to involve the presence of scale insects that are husbanded by the ants for honey dew on young rattan tissue. Ants occupying the ocreas of some species can be extremely aggressive and, in this species, can also be very noisy - producing an alarm call when disturbed by banging their mandibles against the dry ocreas[

Edible Uses

The fruit of all members of this genus is more or less edible. It is sometimes eaten, but there is little flesh and it is therefore more likely to be used as a famine food when little else is available[

All members of the genus produce long and very durable canes and are used to make some of the most durable and attractive carrying baskets in southeast Asia. Unfortunately, the inner epidermis of the leaf sheaths adheres to the stem, making it difficult to clean and leaving the stem lacking the attractive, shiny appearance of many Calamus species. In addition, the nodes are frequently very irregular and marked with shallow pits or the remains of branches The canes are very widely used locally and often traded, but not usually more widely than local markets[
