ACACIA SEEDLINGS. 161 



Stem terete, green, glabrous. First internode 1 to 6 mm.; 

 second 2 to 9 mm.; third to sixth 8 mm. to 1*8 cm. 



Leaves — No. 1. Abruptly pinnate, petiole 4 mm. to 1*2 

 cm., pale green, glabrous; leaflets four to six pairs, oblong 

 to ovate-oblong, 5 mm. to 1 cm. long, 2 to 3*7 mm. broad, 

 upperside green, underside pale green; rachis 8 mm. to 

 2'5 cm., with terminal seta. 



No. 2. Usually abruptly bipinnate, petiole 5 mm. to 1*4 

 cm., glabrous, with terminal seta; leaflets two to four 

 pairs, oblong-acuminate, about 5 mm. long, 1*5 to 2*5 mm. 

 broad, midrib distinct; rachis 8 mm. to 1*7 cm.; stipules 

 minute. 



In one case No. 2 was abruptly pinnate with four pairs 

 of leaflets. In another case the leaf was strictly tripinnate, 

 the basal pair of leaflets having developed as a pair of 

 pinnae, while the terminal pinna had four pairs of leaflets. 

 (Plate X, fig. 8). 



Nos. 3 to 8. Abruptly bipinnate, petiole 1 to 2*8 cm., 

 becoming slightly dilated, with a strong nerve near the 

 lower margin, glabrous; leaflets four to seven pairs; rachis 



7 mm. to 2*4 cm. 



Nos. 9 to 15. These may be linear phyllodes, or abruptly 

 bipinnate, petiole 2*2 to 4*4 cm., dilated from 1 to 2 mm., 

 with distinct midrib; leaflets four to six pairs; rachis 1*3 



to 2'2 cm. 



Nos. 16 to 38. These may be linear phyllodes, or abruptly 

 bipinnate, petiole 3*1 to 8*2 cm.; leaflets three to eight 

 pairs. In the early phyllodes the midrib is so distinct as 

 to make the leaf appear to be uninerved, though by close 

 inspection a finer vein may be seen on each side of the 

 central one. 



No. 20 may be 10 cm. long and 3 mm. broad.
