ferent forms of root-stocks. The plants are liliaceous in 
structure, though otherwise sedge-like. The flowers are 
single or loosely clustered or in spikes or heads; they are 
small and regular, six-parted, the parts glumaceous. In 
contrast to this, the Cyperaceae are destitute of a perianth, 
or with bristles or scales in its place. 
Britton and Brown give forty species of Juncus and 
seven of Juncoides.
