Fertile seeds dark brown, 3 mm. long, 2 mm. broad, thin, usually ovate, slightly 

 concave or scutelliform, slightly wrinkled, and minutely pitted on both sides. Hilum 

 ventral, very small, usually in the centre of the endosperm, sometimes slightly raised, 

 darker than the testa. 



Sterile seeds reddish-brown, very numerous, the majority linear, about 2 mm. 

 long. 



E. di versicolor. 

 " Seeds without appendage.'" (" Eucalyptographia," figs. 11 and 12.) 



Fertile seeds light to dark brown, 3 mm. long, 2 mm. broad, ovate to obliquely 

 ovate, rather thin and slightly scutelliiorm, both surfaces more or less wrinkled. Hilum 

 ventral or nearly so, very small, usually orbicular, darker than the testa. 



Sterile seeds very numerous, reddish-brown, cubiform to awl-shaped, smaller 

 than the fertile seeds. 



E. dec urea. 



" Wingless seeds. Fertile seeds much larger than the sterile, ones, blackish, nearly oblique- 

 tetrahedric." (Mueller.) 



Fertile seeds dark brown, 3 mm. long, 2 mm. broad, ovate to acutely ovate or 

 elliptical, rather thick, wrinkled, and with a few shallow depressions on both sides, 

 the thin testa more or less membranous on the dorsal margin. Hilum ventral, ovate 

 or elliptical, rather small, the attachment scar surrounding it very conspicuous. 



Sterile seeds reddish-brown, very numerous, usually quadrangular-oblong, 

 about half the length of the fertile seeds. 



Series Striolatae. 



Fertile seeds light to dark brown, usually compressed ovate to orbicular, with 

 a small ventral hilum, and both surfaces deeply to finely striate. In a few cases the 

 striae is more or less transverse, or radiating from the hilum. This series includes the 

 Boxes and Ironbarks.
