E. miniata. 



" Fertile seeds large, without any appendicular membrane ; sterile seeds comparatively small and 

 partly very narrow. Fertile seeds 2 J— 4 lines long, angular and often truncated, convex on the outer face, 

 edged around the large circular hilum, thence radiating-streaked to the acute margin of the seed; testa 

 neither much shiny or distinctly reticulated. Sterile seeds 1-1| lines long, mostly on'y between J and 

 § line broad." (" Eucalyptographia r " figs. 8 and 9.) 



Fertile seeds dull, dark brown, 5-9 mm. long, 5-7 mm. broad, moderately thick,
