E. ochrophloia. 

 Fertile seeds rather dull, light to dark brown, 1^—3 mm. long, 1-1^ mm. broad, 

 the majority very thin, somewhat compressed or slightly concave on the inner face, 

 with a small shallow depression surrounding the hilum, slightly convexed on the back, 

 and minutely wavy-striate longitudinally. Hilum ventral or nearly so, very small 

 pale-coloured, the small depression surrounding it shallow and darker than the remainder 

 of the thin testa. 



Sterile seeds glossy, dark reddish-brown, polymorphic, the broad ones more 

 numerous than the thickish narrow ones, all considerably shorter than the fertile 

 seeds. 



Differing from E. prumosa in the somewhat narrower seeds. 



E. Staigeriana. 



" Seeds disk-like." (Mueller.) 

 Fertile seeds dull to slightly glossy, light to dark brown, 1^-2 mm. long, about 

 1 mm. broad, oblong, ovate, obtuse, or acute, a few somewhat triangular with rounded 

 angles, thickish, the back convexed and minutely striate longitudinally to almost 

 smooth. Hilum ventral, very small, whitish, sometimes the depression surrounding 

 it rather broad and shallow, and as long as the face of the seed ; testa thin. 



Sterile seeds glossy, light to dark reddish-brown, polymorphic, the narrow ones 

 awl-shaped, about as numerous as the broad ones and rarely as long as the fertile 

 seeds. 



Somewhat similar to E. populifolia, but larger and thicker.
