ACACIA SEEDLINGS. 157 



No. 2. Abruptly bipinnate, petiole 8 mm. to 2 cm., gland 

 on upper margin, glabrous, with terminal seta; leaflets 

 four to seven pairs, oblong-acuminate, 2 to 8 mm. long, *5 

 to 2 mm. broad, underside reddish-green to pale green with 

 red margins; rachis 9 mm. to 2*3 cm. 



Nos. 3 to 5. Abruptly bipinnate, petiole terete, 1*2 to 

 2'6 cm., gland on upper margin, glabrous; leaflets six to 

 thirteen pairs; rachis 1*5 to 4 cm. 



Nos. 6 to 11. Abruptly bipinnate, with usually two or 

 three pairs of pinnae, common petiole 2*5 to 6 cm., slightly 

 dilated, one to three glands; leaflets twelve to seventeen 

 pairs; rachis 3*5 to 5*7 cm. 



Nos. 12 to 20. Usually abruptly bipinnate with three or 

 four pairs of pinnae, common petiole 4*6 to 6*3 cm. long, 

 1 to 2 mm. broad, glands two or three; leaflets eleven to 

 eighteen pairs, the latter number being on a No. 14 leaf; 

 rachis 3*2 to 5*5 cm. 



Nos. 21 to 30. These may all be abruptly bipinnate and 

 similar to No. 20, or they may be linear phyllodes about 8 

 to 11 cm. long, 2 to 3 mm. broad, with distinct midrib, and 

 one to three glands on upper margin* 



Seedlings of this species two or three feet high may 

 retain many bipinnate leaves, and individuals vary in regard 

 to the number of bipinnate. leaves they may have before 

 the advent of phyllodes. 



For the disposition of glands on the common petioles see 

 under Glands etc. (supra).
