brandies long, their tips much drawn out, flagellate, with 

 their leaves very minute and distant. Leaves alternate, sub-

 ticulate on two margins, the lower side entire and nearly- 

 straight and very slightly decurrent ; teeth few (5-9), very 

 irregular in length, two (sometimes three) outermost at tip 

 very long and straight, their sinuses large and broad. Cells 

 minute, orbicular, sub-opaque.
