 below, sometimes with a faint one above, the common 

 petiole 1 to 2*5 cm., hispid to pubescent; leaflets up to 

 twelve pairs. 



Nos. 17 to 25. Usually linear pungent pointed phyllodes, 



2 to 2*5 cm. long, 1 to 1*5 mm. broad, usually with three 

 nerves, the centre one most prominent and the upper one

 leaves and later with phyllodes.
