Uninerves — Racemose. 



Acacia suaveolens, Willd. "Sweet-scented Wattle." 

 Seeds from Ulladulla, growing on Permo-Oarboniferous 

 sandstone. (Plate IX, Numbers 8 to 10.) 



Seeds black, oblong, 6 to 7 mm. long, 3 mm. broad, 2 mm. 

 thick. 



Hypocotyl erect, terete, pale pink, about 1 to 4 cm. 

 long, 1*3 or rarely 2 mm. thick at base, 1 mm. at apex, 

 glabrous. 



Cotyledons sessile, oblong, apex rounded, sagittate, 7 to 

 8 mm. long, 3 to 3*5 mm. broad, at first erect, but becoming 

 horizontal in a few days, and usually remaining until the 

 phyllodes are present, outer or underside deep red, and 

 showing distinctly, especially when dry, a raised central 

 nerve, and a shorter almost parallel vein on each side 

 thereof, the cotyledon being triplinerved and also having 

 numerous reticulating and anastomosing veins, inner or 

 upperside at first greenish-brown, becoming reddish-green 

 and finally green, glabrous. (Fig. 1.) 



Stem terete in the lower portion, angular above owing 

 to the presence of decurrent leaf-stalks, brownish-green, 

 or sometimes glaucous. First internode *5 mm.; second 

 *5 mm.; third 1 mm.; fourth 1 mm.; fifth 2 to 3 mm., vary- 

 ing in length in different individuals. 



Leaves — No. 1. Abruptly pinnate, petiole 4 to 8 mm. long, 

 glabrous ; leaflets three to four pairs, oblong to obovate- 

 oblong, shortly acuminate, often mucronate, 5 to 7 mm. 

 long, 2 to 3*5 mm. broad, the basal pair usually smaller, 

 underside red or reddish-green, becoming pale green, central 

 nerve distinct, second nerve and reticulating veins show-
