Euc. sp., Kalangadoo. 



Fertile seeds dark brown, rather dull, 2-2|- mm. long, l-l| mm. broad, oblong 

 to obliquely ovate, a few somewhat orbicular, and even oblong, very thin, wrinkled 

 on both sides, and sometimes with a few faint ridges on the face and one on the back, 

 minutely scurfy all over. Hilum ventral, ovate, rather large, the shallow depression 

 surrounding it also large ; testa very thin. 



Sterile seeds glossy, light-yellowish to reddish-brown, the majority narrow, 

 shorter than the fertile seeds. Kalangadoo, South Australia (Prof. J. B. Cleland). 



(b) Fertile seeds not exceeding 2 mm. long, dark-brown ; hilum ventral, usually 

 surrounded by a moderately large, shallow depression. 



E. Smithii. E. viminalis. 



E. elwophora. E. Kitsoniana. 



E. Macarthuri. E. cinerea. 



E. Dunnii. E. nitens. 



E. Smithii. 



Fertile seeds dull, light to dark brown, 1-2 mm. long, 1 mm. broad, oblong to 

 somewhat triangular in shape, compressed, one end sometimes very acute, the other 

 rounded with a few faint ribs, or radial ridges, but not as prominent or as acutely angled 

 as E. Dunnii, more or less wrinkled on both sides, the back minutely pitted. Hilum 

 ventral, rather small, nearly the same colour as the thin testa, the depression varying 

 according to the shape of the seed, but usually shallow and rather large. 



Sterile seeds glossy, reddish-brown, usually very narrow and shorter than the 

 fertile seeds. Wingello (A. Murphy, 1916). 



E. elceophora. 



Fertile seeds shiny, dark brown, 1-2 mm. long, 1-1 \ mm. broad, somewhat 

 compressed-pyramidal to compressed-ovate or orbicular, with 1-4 very faint ridges 

 extending from the hilum to the edge, the back and sometimes the face with shallow 

 wrinkles, the surface covered with a minute, black, scurfy substance, which is fringe- 

 like on the ridges and margin. Hilum ventral, usually large, orbicular, paler than the 

 thin testa. 



Sterile seeds glossy, reddish-brown, the majority narrow, subulate to oblong, 

 straight or curved, the broad ones more irregular, but shorter, the former rarely 

 exceeding 2 mm. long. 



Smaller, less angular and more orbicular than E. Stuartiana. Marulan (J. L. 

 Boorman, 1916).
