E. eudesmioides. 



Large, black, irregular in shape, with a distinct hilum, the margin encircled with 

 a narrow membrane. Sterile seeds many, brown. (Minginew, W.A., J.H.M.) 



Fertile seeds dark brown, 4-5 mm. long, 3 mm. broad, usually oblong or ovate in 

 outline, surrounded by a pale, thin, membranous wing and sometimes with another 

 irregular membrane extending partly over the centre of the endosperm, which is rather 

 soft, protected by a very thin testa-like membrane, which is more or less reticulate in 

 appearance, the inner face marked with slight depressions, the back moderately smooth, 

 and slightly pitted. The seeds are very light for their size. Hilum ventral, rather 

 large, ovate to orbicular, lighter in colour than the seed. 



Sterile seeds red brown, less than 2 mm. long, usually quadrangular or cubiform, 

 very numerous. 



E. tetragona. 



" Fertile seeds surrounded by a narrow, tender membrane . . . very angular, much larger 

 than the sterile seeds." (" Eucalyptographia.") 



Fertile seeds dark brown, 4-6 mm. long, 3 mm. in diameter, ovate, surrounded 

 by a pale, thin, but very distinct membranous Aving, which sometimes is fully half as 

 broad as the endosperm ; the inner face is often marked with an irregular longitudinal 

 membrane, and 3-4 smaller transverse ones, the back smooth and shiny, more or 

 less concave, owing to the upturned outer membrane. The seed is very light for its 

 size ; it is also soft. Hilum ventral, usually ovate, rather large, paler than the seed. 



Sterile seeds red-brown, very angular, 1^-2 mm. long, glossy, pitted rugose, 

 very numerous. 



E. tetraptera. 



" Seeds without any broad membranous appendage. Sterile seeds variable in width, but ususally 

 much more slender than the fertile seeds." (" Eucalyptographia.") 



Comparatively few fully-developed seeds, which are broad, irregular in thickness and outline, dull 

 black, dotted ; thinnish round the edge, but without membrane. The numerous sterile seeds shiny, narrow 

 reddish-brown to black. (Near Stirling Range. Cape Riche, 3622/] 8.) 



Fertile seeds very dark brown or nearly black, 4-5 mm. long, and about as broad, 

 ovate to nearly orbicular in outline, surrounded by a thin, undulate membrane, which 

 is about half as broad as the endosperm ; the inner face somewhat alveolate, with cell- 

 like depressions or short, irregular, rudimentary wings or ridges, the back moderately 

 smooth, but distinctly marked with reticulate veins. The wing-like membrane is so 

 thin that it rolls over with the slightest touch or pressure. Hilum ventral, usually 

 orbicular, rather small and often concealed by a thin membrane. 



Sterile seeds oblong to awl-shaped, 2-4 mm. long, of a reddish-brown colour.
