160 R. H. CAMBAGE. 



sometimes be confluent with the first or lower vein at both 

 ends, but this latter feature is noticed less in the later 

 phyllodes. The first phyllode in Number 7, Plate III, has 

 a fourth vein above the others, extending from the base to 

 nearly the middle of the upper margin. The small insig- 

 nificant vein extending from the gland towards the base 

 may be seen in phyllodes of this species as in those of A. 

 penninervis and A. Mabellce. 1 



Bentham describes the phyllodes of A. binervata as 

 having two or three longitudinal nerves. The mature 

 phyllodes are usually 2-nerved, and this fact, as in the 

 somewhat similar case of A. stricta, (supra), is suggestive 

 of the possibility that, as the species developed, it reduced 

 the number of veins in the phyllodes. 



Plurinerves — Juliflorse — Falcatae. 



Acacia Maideni, P.v.M., " Sally." Seeds from Milton. 

 Growing on a moderately siliceous soil. (Plate IV, 

 Numbers 1 to 3.) 



Seeds black, oval-oblong, 4 mm. long, 3 mm. broad, 1*5 

 to 2 mm. thick. 



Hypocotyl erect, terete, pale green, up to 2*5 cm. long, 

 2 mm. thick at base, *5 to 1 mm. thick at apex, glabrous. 



Cotyledons sessile, slightly auricled, oval-oblong, about 

 6 mm. long, 3 mm. broad, outer or underside at first yel- 

 lowish-green, becoming pale green, with one or two raised 

 lines along centre, upperside at first yellowish-green, 

 becoming dark green within a week, glabrous. 



On one plant the cotyledons were fused along one side, 

 and appeared as one, almost encircling the stem, the line 

 of fusion being undiscernible.
