Abundant at low altitudes everywhere in Hupeh and Szech'uan where it is 

 known as the " ko t'eng." The fibre from the shoots is made into a coarse cord 

 and is employed as a slow-burning fuse to explode the native gingals and match- 

 locks. This fibre is also more elaborately perpared and made into a textile cloth 

 known as " ko-pu." From the thickened rootstock starch is prepared as a food. 

 This starch (ko-feu) is, however, but little valued and is only used in times of 

 scarcity and by the poorer peasants. E. H. W.
