that it is highly probable they will all be hereafter con- 

 sidered varieties of the same. 



Branches slender, erect, deeply furrowed. Plii/llodia 

 linear-lanceolate, falcate, tapering to the base, obtuse at 

 the point, which is formed by a short, brownish, recurved 

 mucro ; a minute gland is present just above the base ; the 

 central rib, and all the numerous lateral elevated veins, are 

 covered with minute patches of whitish matter exuded 

 through the cuticle, and giving the phyllodia a gray pow- 

 dery appearance. Peduncles axillary, simple, divaricating, 

 pubescent, 2 or 3 together, rather longer than, or about 

 the same length as, the pale-yellow heads of flowers.
