Sterile seeds shiny, reddish brown, polymorphic or in irregular narrowish flakes 

 3-6 mm. long. 



Deeper in colour, more rugose and broader on the face, and somewhat more 

 winged on the ends than E. corymbosa. 



E. calophylla. 



" Seeds large, ovate, black, flat, or with a raised angle on one face, the edges acute but scarcely 

 winged, the hilum large on the inner face." (B.Fl. Ill, 256.) 

 Bentham's contrast in the Key (B.Fl. Ill, 199) is — 



Seeds large not winged E. calophylla, 



Seeds (very irregularly) winged ... ... ... ... ... E.jicifoha. 



'' Fertile seeds very large, black, at the dorsal edge acute, not produced into a membranous appendage ; 

 sterile seeds very much smaller, narrow." (" Eucalyptographia," figs. 9 and 10.) 



Fertile seeds glossy, jet black, like fragments of coal, 5-16 mm. long, 5-7 mm. 

 broad, navicular, sharply keeled or winged, the margin almost transparent, smooth 

 and minutely pitted on the sides ; the face wrinkled with short irregular ridges and 

 shallow depressions between them. Hilum ventral, scarcely in the centre of the 

 endosperm, large, linear to ovate, much paler than the hard testa. 



Sterile seeds glossy, dark brown, polymorphic, flaky to quadrangular, nearly 

 all narrow. 



Larger and darker and with a more conspicuous hilum than any of the allied 

 species. 



E. calophylla var. rosea. 



Large percentage fertile, large, lance-headed, with a large, dull hilum near one margin, thin towards 

 the edges, but not membranous. (Rydalmere, Sydney, Dr. Prior, 1918.) 



Fertile seeds glossy, brown, 10-12 mm. long, 4-6 mm. broad, compressed navicular, 

 the dorsal edge more or less winged, sometimes attenuated at one end and produced 

 into a short semi-transparent wing, slightly wrinkled and pitted on the sides, rugose 

 and wrinkled on the face or ventral portion. Hilum ventral, scarcely in the centre 

 of the endosperm, large, ovate, paler than the thin firm testa. Sterile seeds glossy, 

 reddish, narrow, somewhat flaky, 4-7 mm. long. 



Paler and thinner and with a more oblique hilum, and also more prominently 

 winged than E. calophylla. 



(b) Fertile seeds reddish-brown to jet black, 3-10 mm. long, broadly navicular, 

 compressed dorsiventrally into a more or less thickened keel, the margin usually acute 

 or expanded into a narrow membranous-like wing as in E. trachyphloia. 



Sterile seeds dark brown to reddish brown, polymorphic, somewhat scaly and 



resinous-like. 



E. Watsoniana. E. maculata. 



E. eximia. E. peltata. 



E. citriodora. E. trachyphloia. 



E. Bloxsomei.
