1GS 



space between the ridge uneven, or irregularly rugose, sometimes showing traces of 

 very fine striae, the back slightly convexed, glossy and faintly rugose. Hilum ventral, 

 orbicular, large, much depressed, usually whitish. 



Sterile seeds 4-6 mm. long, red-brown, very variable, the broad ones thin, nearly 

 as broad as long, the narrow ones terete or nearly so ; some, however, are more or less 

 triangular. Dongarra, Western Australia (E. W. Clarkson). 



E. tetrodonta. 



" Sterile seeds not much narrower than the fertile seeds, all without any membranous appendage. 

 Sterile seeds often narrow-pyramidal and truncated, fertile seeds mostly oblique-oval." (" Eucalypto- 

 graphia," figs. 6 and 7.) 



Only two good seeds seen, and these are fertile ones, sub-hexagonal or nearly 

 circular, slightly convex, brownish-black, no wing. In the middle of the concave side 

 a hexagonal hilum, with six slightly raised ribs, radiating to the circumference. 



Fertile seeds dull, brown, 4-6 mm. long and about as broad, orbicular to somewhat 

 quadrangular in outline, compressed but moderately thick, the ventral marked with 

 5-7 radiating ridges, the space between them concave and minutely pitted rugose* 

 the dorsal much convexed, smooth or slightly rugose. Hilum ventral, orbicular, rather 

 large and sometimes deeply depressed, or much lower than the somewhat ridged surface 

 surrounding it. 



Sterile seeds glossy, dark brown, compressed, usually angular, the broad ones 

 somewhat pyramidal, the longest rarely exceeding 3 mm. 



Fertile seeds smaller and more compressed than those of E. erythrocqrys. Darwin 

 (N. Holtze, 1905). 



Series Cochleatffi. 



Fertile seeds light to dark brown, 2-8 mm. long, more or less D-shaped to 

 triangular ; the thin firm testa expanded from the dorsal into a narrow or broadish 

 membrane or wiirg ; the ventral usually marked with two or three well-defined ridges, 

 Hihrm terminal, rather small. 



Sterile seeds angular, subulate to broadly D-shaped. 



E. buprestium. 

 E. pachyloma. 



E. buprestium. 



" Perfect seeds very few, large, very irregularly shaped, the acute edge sometimes exj>anded into a 

 narrow wing." (B.FL III, 206.) 



Fertile seeds very angular, not much differing in size from the rather large and broad sterile seeds, 

 but edged by a rather conspicuous membrane." (" Bucalyptographia," figs. 8 and 9.)
