Calamus dumetosus is a spiny, clustering rattan palm (sometimes called a climber) native to Borneo, growing in tropical lowland dipterocarp forest. It is rare in the wild and is not known as a house or garden plant, so its care is largely untested.
Calamus dumetosus, synonym Retispatha dumetosa, is a species of flowering plant in the palm family endemic to Borneo, where it is rare and known as wi tebu bruang (dialectal: wi tebi bagadap) or 'the bear's sugar cane'. The specific epithet dumetosus means 'bushy'. As Retispatha dumetosa it was the only species in the genus Retispatha. While classified with other rattans, it retains only superficial climbing organs; it sprawls and leans but is not a true climber.
Calamus dumetosus is scattered across Borneo forming dense patches in hills and valleys of Dipterocarp forests, absent from the montane and heath varieties. No local uses have been recorded.
