Description

They are dioecious,[5] mostly leaf-climbing lianas with slender, reedy stems. To aid scrambling some species have evolved hooks on the underside of the midrib, or more commonly by modified "pinnae" or tendrils in the form of stout, backward-pointing spines. These stems may grow to lengths of 200 metres.[6][7]

The fruits of certain species, in particular Calamus draco, produce a red resin known as "Dragon's blood".[8]
