(a) Prominently striate. 



Fertile seeds light to dark brown, l|-3 mm. long, ovate, and more or less obtusely- 

 angled to somewhat triangular, inclines to be deeply pitted-striate on both surfaces. 

 Western species. 



E. erythronema. E. fcecunda. 



E. astringens. E. platypus. 



E. Websteriana. E. torquata. 



E. erythronema. 



" Fertile seeds considerably larger than the sterile seeds, all without any appendage." (" Eucalypto- 

 graphia," figs. fl and 10). 



Fertile seeds glossy, light brown, 1-lJ mm. long, about 1 mm. broad, very 

 irregular, ovate, oblong or triangular, somewhat thick, minutely longitudinally pitted- 

 striate, rather plump, many acutely angled. Hilum ventral, rather small, usually 

 ovate ; testa thin. 



Sterile seeds very numerous, very glossy, bright to reddish brown, angular, 

 quadrangular to oblong, the majority shorter and narrower than the fertile seeds. 



E. astringens. 



Fertile seeds light to dark brown, \\ mm. long, 1 mm. broad, oblong to irregularly 

 ovate, minutely longitudinally pitted, striate on both surfaces. Hilum ventral, ovate 

 to orbicular, the depression surrounding it sometimes rather broad ; testa thin. 



Sterile seeds glossy, reddish-brown, very numerous, and very irregular in shape, 

 the majority about half the size of the fertile seed. 



Differing from E. platypus in being more irregular, and in the hilum being more 

 in the centre of the endosperm. 



E. platypus. 



" Sterile seeds varying in form; the fertile ones about half a line long, black, ovate-rotund. Seeds 

 wingless, the fertile ones faintly clathrate. 



" Seeds all without any appendage, the fertile seeds blunt-angled, dotted streaked, the sterile seeds 

 mostly shorter and always narrower. Fertile seeds not fully a line long ; some of the sterile seeds 

 considerably longer than the rest." (" Eucalyptographia," as E. obcordata, figs. 8 and 9). 



Fertile seeds glossy, dark brown, 1^ mm. long, 1 mm. broad, ovate to somewhat 

 oblong, minutely stiiate all over. Hilum ventral, scarcely in the centre of the endo- 

 sperm, small, ovate to orbicular, sometimes oblong, deep sunk; testa very thin. 



Sterile seeds glossy, reddish-brown, the broad ones shorter than the fertile seeds, 

 the narrow or subulate ones sometimes longer than the fertile seeds, and more 

 numerous than the broad ones.
