(a) Large, elongated-pyramidal. 



Fertile seeds light brown to jet black, 3-7 mm. long, l|-4 mm. broad, somewhat 

 oblong to elongated or obliquely pyramidal, with 3-5 diverging ridges, the back 

 moderately smooth. Hilum terminal, rather large in E. marginata. 



Sterile seeds pyramidal to D-shaped, much smaller than the fertile seeds. 



E. marginata. 

 E. gigantea. 



E. marginata. 



" Seeds all very angular and without any appendage, the sterile mostly not narrow, but smaller 

 than the rather large fertile seeds. Seeds forming two rows in each cell ; the fertile grains 1^-2| lines 

 long, black, somewhat shining, much fewer than the sterile seeds, which are pale-brownish and 1-J-l lines 

 long, and nearly as broad." (" Eucalyptographia," figs. 9 and 10.) 



Fertile seeds jet black, glossy, 4-7 mm. long, 3-4 mm. broad, minutely rugose, 

 the majority usually narrow or elongated and angular, the broader ones more or less 

 pyramidal, with 3-5 prominent ridges radiating from the hilum, the back moderately 

 smooth and much convex. Hilum terminal, usually whitish, its shape largely depending 

 on the shape of the seed, e.g., compare (a) with (r). It is, however, very conspicuous. 



Sterile seeds very light to dark brown, D-shaped to pyramidal, barely 3 mm. 

 long, less numerous than the fertile seeds. King George's Sound, Western Australia 

 (J.H.M., September, 1909). 



E. gigantea. 



Fertile seeds light brown, glossy, 3 mm. long, 1-lJ mm. broad, oblong, semi- 

 ovate to obliquely D-shaped, usually with 1-3 small acute ridges on the inner face, 

 sometimes the lower half quite smooth, semi-ovate, the back smooth, faintly pitted. 

 When face downwards the long, smooth back is oblong-ovate in outline. Hilum 

 terminal or nearly so, very small and sometimes difficult to discern ; testa firm, rather 

 thin. 



Sterile seeds light brown, somewhat darker than the fertile seeds, very angular, 

 shorter and slightly smaller, and often without the long, smooth back of the fertile 

 seeds. Hilum terminal and usually easy to find ; testa very hard and brittle.
