ACACIA SEEDLINGS. 159 



margin, glabrous; leaflets six to ten pairs; rachis 1*5 to 

 2*5 cm. 



Nos. 10 to 20. Linear-lanceolate one-nerved phyllodes 

 with nerve-like margins, from about 1*3 to 2*7 cm, long, 

 2 to 4 mm. broad, narrowed towards the base, mucronate, 

 usually with small marginal gland, glabrous. 



This seedling is quite different from that of A. obtusata 

 (Part IV, 424, 1918), a species with which it has affinities, 

 and in most cases the petioles of the last two bipinnate 

 leaves are longer than any of the first twenty phyllodes. 



Plurinervbs — (Triangulares). 

 Acacia amblygona A. Ounn. Seeds from Tottenham, New 

 South Wales. Plate IX, Numbers 6 to 8. 

 Seeds black, obliquely oval to obovate, 3*5 to 4 mm. long, 

 2 to 2*5 mm. broad, 1*5 mm. thick. 



Hypocotyl terete, greenish to reddish-brown and red, 1*5 

 to 2 cm. long, about 1*5 mm. thick at base, about 7 mm. at 

 apex. 



Cotyledons sessile, auricled, oblong to oblong-oval, 4 to 

 5 mm. long, 2 to 2'5 mm. broad, upperside reddish-green, 

 underside reddish-brown with perhaps two or three raised 

 lines, sometimes with warty surface, remaining erect and 

 falling in two or three days, or earlier than those of any 

 other species yet examined. 



Stem terete, hirsute to tomentose. First internode *5 

 mm.; second 1 mm.; third 1 to 2 mm.; fourth and fifth 2 

 to 4 mm.; sixth to eighth 3 to 5 mm. 



Leaves — Nos. 1 and 2. Abruptly pinnate, forming an 

 opposite pair, petiole, about 3 to 4 mm.; leaflets two pairs, 

 oblong-acuminate, 3 to 6 mm. long, 1*5 to 2 mm. broad, 

 venation obscure, upperside green, underside pale green 

 to reddish; rachis 2 to 3 mm., green, glabrous, with 

 terminal seta; stipules acuminate scales 1 mm. long.
