 Fertile seeds without wings or sometimes with a very narrow dorsal or marginal 

 rudimentary wing, narrow to broadly navicular, compressed laterally or dorsiventral, 

 and with a more or less prominent keel. Hilum ventral. 



Sterile seeds dark reddish brown to jet black, scale-like to somewhat flaky, 

 smaller than the fertile seeds.

E. Nowraensis. E. eximia. 



E. calophylla. E. citriodora. 



E. calophylla var. rosea. E. maculata. 



E. peltata. 

 E. trachyphloia. 



(a) Fertile seeds 5-16 mm. long, narrow, navicular, compressed laterally into 

 a very narrow membranous-like wing along the keel, which sometimes becomes slightly 

 more elongated at both ends. 



Sterile seeds dark brown to reddish brown, scale-like to somewhat flaky, smaller 

 than the fertile seeds. 



E. corymbosa. E. calophylla. 



E. Nowraensis. E. calophylla var. rosea. 



E. corymbosa. 



"' Seeds large, ovate, more or less bordered by a wing, usually narrow." (B.Fl. Ill, 256). 



Fertile seeds large, provided with a narrow or short appendicular membrane; sterile seeds much 

 smaller." (" Eucalyptographia," figs. 9 and 10.) 



Lance-shaped or lunate, thick, the thick portion with a hilum at the side, the keel continued 

 into a narrow membrane. Fertile seeds brown, numerous." (J. H. Maiden, Como, Sydney, 1916.) . 



Fertile seeds dull, pale brown, 6-8 mm. long, 3 mm. broad, navicular, the ventral 

 portion moderately straight, keeled on the back, the dorsal edge bordered by a narrow 

 scarcely membranous wing. Sides moderately smooth, the inner edge rough and 

 somewhat crested. Hilum ventral, rather large, usually in the centre of the endosperm; 

 testa thin, very firm. 



Sterile seeds glossy, reddish brown, very irregular, the majority compressed 

 scale-like to flaky, 2-5 mm. long, \-\\ mm. broad. 



Slightly longer and paler than E. Nowraensis, and also with a more prominent 

 dorsal wing.

Fertile seeds shiny, dark reddish brown, 5-7 mm. long, 2-3 mm. broad, navicular, 

 the dorsal keel more or less winged, especially at both ends, the face truncate, muricate
