ramifications . 
Stem depressed^ very much branched. Branches alternate; very long; alter¬ 
nately winged; with an odd one at tlie end. Wings cut into winged clefts; 
segments thick; awl-shaped and fructifying at the ends. This plant is

F. obtu'sus. Gristly, thread-shaped, compressed, branched, doubly
