Low mangrove or nepa palm banks characterize these streams; and occasionally slight eminences, with timber, are to be seen.
With its four hind legs the nepa swims, but at a very slow pace.
Notanecta and nepa are of the same order, but are true water-bugs, formed for diving and sub-aqueous life.
After two days' paddling from the mouth of the Rejang, the boats arrived at Sibou, where there is a manufactory for nepa salt.
The nepa is a variety of bamboo grown near shallow sea water.
The nepa palm grows down to the edge of the banks, which are washed by a salt tide, and furnishes the Dyak with many necessaries.
One (nepa cinerea) which was put into a basin of water with several young tadpoles, killed them all without attempting to eat one.
Ginseng is found wild in the mountain forests of eastern Asia from nepa to Manchuria.
