long; leaflets six to eight pairs, the number not always 
equal on each pinna of the same leaf, up to 7 mm. long; 
rachis 2 to 2°3 cm. long. 
Nos. 5 and 6. Abruptly bipinnate, petiole up to 4 mm. 
broad in the case of No. 6, gland towards base, 1°5 to 3°9 
cm. long; leaflets eight to ten pairs on either; rachis up to 
3°7 cm. long. 
Nos. 7 and 8. Abruptly bipinnate, sometimes with two 
pairs of pinne, petiole up to 6 mm. broad in No. 7 and 9 
mm. in No. 8, with the midrib below the centre of the 
lamina, 2°7 to 4°7 cm. long; leaflets eight to eleven pairs. 
Nos. 9 and 10. Abruptly bipinnate, sometimes with two 
pairs of pinnse, petiole up to 4°7 cm. long, 1 cm. broad, 
gland near base; leaflets nine to eleven pairs. 
Nos. 11 and 12. Abruptly bipinnate, often with two pairs 
of pinnee, petiole up to 4°3 cm. long and 1°4 cm. broad. 
Nos. 13 and 14. Leaflets sometimes up to fourteen pairs. 
This species is very variable in regard to the stage at 
which phyllodes appear. In one case No. 9 was reduced 
toa phyllode while several later leaves were bipinnate. On 
plants two feet high there may be numerous leaves with 
petioles developed as broad phyllodes, but having one, two 
and even three pairs of pinne (Fig. 1). There is usually a 
gland at the base of the dilated petiole, and also at the 
_ bases of the second and third pairs of pinnee.
