The rbacliis and pedicels are margined with a thin, irregularly broken, transpai*ent 

 membrane, which is edged with short clubbed or obtuse processes, or teeth, which also 

 occur on the edges of the bracts. The flowers are very minute in proportion to the 

 rather long pedicel and ovary, and are opposite to each other, singly or in pairs, for the 

 whole length of the raceme.
