Calamus L. Palmae (in). 280 palaeotrop., mostly leaf-climbers with 

 thin reedy stems. In some there are hooks on the back of the mid- 

 rib, but the more common type of 1. is one in which the pinnae at 

 the outer end are repres. by stout spines pointing backwards (cf. 

 Desmoncus). The 1. shoots almost vertically out of the bud up 

 among the surrounding veg., and the hooks take hold. The stem 

 often grows to immense lengths (500 600 ft.) ; the plants are 

 troublesome in trop. forests because the hooks catch. The stripped 

 stems (rattan canes q.v.), are largely used for making chair bottoms, 

 baskets, cables, &c.
