that it is highly probable they will all be hereafter con- 
sidered varieties of the same. 
Branches slender, erect, deeply furrowed. Phyllodia 
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.
