E. leucoxylon. 



" Fertile seeds finely net-veined, as well as the ranch narrower sterile seeds, usually very small 

 and without any expanding membrane." (" Eucalyptographia," figs. 11 and 12). 



Fertile seeds rather dull, dark-brown, 1 to \\ mm. long, nearly \\ mm. broad, 

 ovate to orbicular, compressed, but slightly thicker than E. Dawsoni, the back minutely 

 longitudinally striate, the face slightly pitted rugose, and with one or two obtuse ridges. 

 Hilum ventral, rather large, usually orbicular, paler than the thin testa, the depression 

 surrounding it not large, rather shallow, and sometimes oblique. 



Sterile seeds glossy, dark reddish-brown, the broad ones cubiform to triangular ; 

 the narrow ones, which are more numerous, subulate, clavate, and usually as long as 

 the fertile seeds. Near Myponga, South Australia (W. Gill, April, 1918). 



E. Caleyi.. 



Fertile seeds rather dull, light to dark brown, 1 to 1^ mm. long, about 1 mm. 

 broad, ovate angular to somewhat triangular, a few rather thick and somewhat pyramidal, 

 with obtuse ridges radiating from the vicinity of the hilum, the back convex and minutely 

 striate longitudinally. Hilum ventral very small, the depression surrounding it very 

 often obscure ; testa thin. 



Sterile seeds glossy, light to dark reddish-brown, polymorphic, the broad ones 

 more numerous than the narrow, subulate ones, the former often about -J mm. long, 

 the latter sometimes 1^ mm. long. 



Differing from E. albens in being smaller and more angular. 7 miles from 

 Ashford (Forestry Commission of New South Wales). 



E. sideroxylon. 



Fertile seeds rather dull, dark -brown, l-l|- mm. long, about 1 mm. broad, rather 

 thick, ovate, oblong to P-shaped, a few somewhat orbicular, moderately compressed 

 to very slightly pyramidal, convex and minutely striate longitudinally on the back. 

 Hilum ventral, very small, and also the shallow depression surrounding it ; testa thin. 



Sterile seeds glossy, light to dark reddish -brown, polymorphic, the narrow ones 

 1-2 mm. long, the broad ones usually shorter than the fertile seeds, both forms 

 apparently of equal proportions. 



Closely allied to E. hemiphloia. Dubbo (J. L. Boorman, 1916). 



E. siderophloia. 



. " Seeds all without appendage, the sterile seeds not very narrow." (" Eucalyptographia," figs. 10 

 and 11.)
