depressed space surrounding the hilum, the ridges more prominent than in E. megacarpa, 

 the space between, depressed and very minutely pitted rugose, also the broad convexed 

 back. Hilum terminal, greyish and conspicuous. 



Sterile seeds 4-5 angled, somewhat similar in shape to the fertile seeds, but 

 only about half the size, usually light to dark brown. 



Larger than E. megacarpa, and with rather smooth ridges. Wooli State Forest, 

 Wooli (G. Boyd, November, 1919). 



E. megacarpa. 



" Seeds very angular, the fertile of nearly the same size as the sterile seeds, all without appendage.' ' 

 ("Eucalyptographia," figs. 10 and 11.) 



Fertile seeds dark brown to black, shining, 4-5 mm. long, 2-| mm. broad, irregularly 

 3-4 angled, with as many more or less prominent nerves or ridges, each nerve or ridge 

 commencing at the outer edge of the moderately broad and distinct greyish hilum, 

 and extending to the margin ; the space between the nerves or ridges usually depressed 

 or concave, and microscopically striate, the ridges smooth or rugose, the back convex, 

 striate. Hilum terminal, the space surrounding it often broad, but its size is largely 

 controlled by the angles of the seed. 



Sterile seeds light to dark brown, angular, irregularly oblong, usually slightly 

 longer than the seeds. 



Differing from E. Planchoniana mainly in size, and in the somewhat roughish 

 ridges. Centennial Park, Sydney, cult. (J. L. Boorman, 1918.) 



(d) Medium; fertile seeds dark brown to jet black. 



Fertile seeds dark brown to jet black, 1-3 J mm. long, pyramidal to D-shaped, 

 usually with three to four prominent angles or ridges, and minutely pitted-rugose. 

 Hilum terminal, rather large. 



Sterile seeds cubiform to D-shaped.
