154 R. H. CAMBAGE. 



sometimes obovate, 3 to 7 mm. long, 1 to 2 mm. broad, 

 upper and undersides pale green, midrib distinct; rachis 2 

 to 4 mm., green, glabrous, with terminal seta. 



No. 2. Abruptly bipinnate, petiole 7 mm. to 1*5 cm., 

 terete or slightly dilated, faintly pilose, green, with ter- 

 minal seta; leaflets one to two and a half pairs, often 

 unequally pinnate, 1 to 3 mm. long, '5 to 2 mm. broad, 

 slightly mucronate; rachis 3 to 5 mm. with terminal seta; 

 stipules minute flat acuminate scales. 



No. 3. This may be a phyllode, or bipinnate, petiole 1*3 

 to 1*5 cm. long, up to 1 mm. broad, midrib below the centre 

 of lamina; leaflets one to two pairs, usually smaller than 

 those of No. 2; in one case only one pinna appeared but the 

 terminal seta was present. 



Nos. 4 to 10. Linear phyllodes, from about 1*3 to 2 cm. 

 long, 1 to 2 mm. broad, narrowed at the base, obtuse, with 

 the apex often curved outwards and downwards, more so 

 than in later phyllodes, slightly mucronate, with sometimes 

 a minute gland showing in a depressed portion of the upper 

 margin near the base, midrib above the centre of the lamina 

 which is unusual in early phyllodes. (See under A. falcata, 

 Part II, 151). Bentham mentions that on mature plants 

 the prominent nerve is very near the lower margin. 1 



This is the fourth seedling described in this series where 

 the No. 3 leaf has been reduced to a phyllode, the previous 

 ones being A, excelsa, A. alata, and A. aspera,
