Nos. 3 and 4. Abruptly bipinnate, petiole usually slightly 

 dilated, with distinct nerve along lower margin, pilose to 

 hoary, excurrent; leaflets three pairs on No. 3, four pairs 

 on No. 4; rachis green, pilose, excurrent; stipules reduced 

 to scales. 



Nos. 5 and 6. Abruptly bipinnate, petiole vertically 

 flattened from 1"2 to 2*5 cm. long, with a prominent nerve 

 following the base of the lower margin for about one fourth 

 the length of petiole, and beyond this point being slightly 

 removed from the margin, the remainder of the petiole 

 being finely striate with parallel veins; pilose to hirsute; 

 leaflets four pairs. 



Nos. 7 and 8. Phyllodes, oblong-falcate, narrowed at both 

 ends, with two distinct nerves, the lower one the more 

 prominent, and becoming confluent towards the base of the 

 lower margin with another distinct nerve which follows 

 the lower margin from the base for a short distance beyond 

 the point of contact with the prominent nerve.
