Rather woody, 4 to 6 inches high ; growing in a compact 
bundle ; livid, yellowish; black when dried, Branches nu- 
merous, divided and sub-divided, their extremities forked. 
Lower branches always rounded, upper ones sometimes flatted, 
and ending in long pods with a fork at the extremity, Gmetin 
fuc. 86, Linn, in Syst. Nat, includes the F, barbatus of Sp. pl. 
as a variety of this, In our specimens, as in Gmelin’s figure, 
the thread-shaped branches swell out into pod-like substances, 
principally towards their extremities. These pods have generally 
more or less length of the thread-shaped branch continued be- 
yond them, but without any leafits, divided into blunt segments, 
_ It is evident therefore that the Linngan specific character does 
not apply well to the plant we have been accustomed to call F. 
feniculaceus.
