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

 broad, rarely exceeding 1 mm., the narrow ones sometimes more than 1 mm. long. 



Differing from E. albens and E. hemi'phloia in being slightly smaller and to some 

 extent more polymorphic. Stuart Town (A. Mnrphy). 



E. intertexta. 



Fertile seeds rather dull, light to dark-brown, 1|— 2 mm. long, about 1 mm. 

 broad, rather thin, with slightly revolute margins, oblong to ovate-acute, with 

 somewhat obtuse angles, the very thin ones concave and much wrinkled on the back, 

 all striate longitudinally. Hilum ventral, almost in the centre of the endosperm, 

 rather large, and also the shallow depression surrounding it ; testa thin. 



Sterile seeds glossy, pale brown, all very small and more or less cubiform, the 

 majority about \ mm. long. 



Differing from E. albens and its allies in the thinner fertile seeds and in the smaller 

 sterile seeds. Broken Hill (E. C. Andrews 1919). 



E. microtheca. 



" Fertile seeds considerably larger than the sterile seeds, all without any appendage." (" Eucalypto- 

 graphia," figs. 9 and 10.) 



Fertile and sterile seeds alike, warm-brown, small, rice-like (? unique). 



Fertile seeds rather dull, light brown, l|-2§ mm. long, about 1 mm. broad, ovate 

 oblong to nearly orbicular, a few slightly angular and oblique; some are also acute at 

 both ends, and occasionally the margin is membranous, but in the majority of cases 

 it is thick; back convex, minutely striate longitudinally. Hilum ventral, ovate to 

 orbicular, pale or dark colomed, usually surrounded by a large depression in the large 

 seeds, and a very small, often quite obscure, depression in the small seeds, which are 

 more conical; testa thin. 



Sterile seeds glossy, yellowish-brown, very small, polymorphic, the majority 

 shrivelled and scale-like, a few of the larger ones about 1 mm. long. 



Differs from E. intertexta and its allies in the rudimentary membrane, and in 

 the lighter colour of the fertile seeds. Bourke (A. Murphy, 1915.) 



E. fasciculosa. 



Fertile seeds rather dull, dark brown, 1 to 2 mm. long, 1 mm. broad, ovate, 

 orbicular to obtusely triangular, rather thin and somewhat concave, the back convex, 

 minutely striate longitudinally, the strias very distinct. Hilum ventral, very small, 

 the depression surrounding it rather large, sometimes darker than the thin testa.
