over, and usually with about two fairly prominent ridges extending from the truncate 

 hilum to the end of the seed, the margin somewhat expanded or acute. Hilum terminal, 

 Small, often thicker on the inner face ; testa thick, brittle. 



Sterile seeds glossy, yellowish-brown, similar to the fertile seeds, but with more 

 rounded edges and more compressed. 



Differing from the majority of the D-shaped series in colour and fewer ridges. 

 Queensland (per F. M. Bailey, May, 1913). 



E. pilularis var. pyriformis. 



Fertile seeds glossy, dark-brown, 2-3 mm. long, 1-2 mm. broad, thick, somewhat 

 D-shaped to obliquely pyramidal, with two to four radiating ridges extending from the 

 hilum to the prominent edge, minutely pitted rugose, truncate at the hilum. Hilum 

 terminal, rather large, paler than the firm testa, and the ridges. 



Sterile seeds glossy, light to dark reddish -brown, somewhat similar to the fertile 

 seeds, but smaller, and without the rather prominent pale ridges. 



Slightly larger than the typical form. Bucca Creek, South Grafton to Dalmorton 

 (J. L. Boorman). 



E. pilularis. 



" Sterile seeds mostly not much narrower than the fertile seeds, all without appendage." (' : Eucalyp- 

 tographia," figs. 10 and 11.) 



Fertile seeds glossy, light brown, 1^—2 mm. long, 1-lJ mm. broad, somewhat 

 pyramidal to D-shaped, the base rather broad, surrounded by a distinct sharp rim 

 which connects with the 3-5 radial ridges, the face and back minutely pitted rugose. 

 Hilum terminal, usually orbicular, testa firm. 



Sterile seeds glossy, reddish-brown, polymorphic, the majority D-shaped and 

 slightly smaller than the fertile seeds. 



In colour and size it resembles E. hamiastoma and E. obtusiflora. Wyong (J. L. 

 Boorman, 1915). 



E. macrorrhyncha. 

 " Sterile seeds not very narrow, all without appendage." (" Eucalyptographia," figs. 9 and 10.) 



Fertile seeds glossy, dark brown, 1^-2| mm. long, the majority about 1 mm. 

 broad, somewhat D-shaped to obliquely pyramidal, with about three radiating, rather 

 acute, ridges extending from the hilum to the thin edge of the seed, minutely pitted 

 rugose ail over. Hilum terminal, paler than the rather firm testa.
