E. alpina. 



" Seeds without any appendage, the sterile seeds mostly not very narrow." (" Eucalyptographia," 

 Fertile seeds shown at fig. 8.) 



Fertile seeds glossy, jet-black, 3 mm. long, 2 mm. broad, angular and somewhat 

 °bliquely D-shaped, slightly, concave on each side, the inner face marked with two or 

 three sharp ridges, the back convexed, pitted rugose. Hilum terminal or nearly so, 

 ovate, whitish ; testa somewhat hard, but much softer than the sterile seeds. 



Sterile seeds glossy, reddish-brown to dark brown, 3 mm. long, 1-1 J mm. broad, 

 more or less oblong, quadrangular to triangular, minutely pitted or longitudinally 

 striate. More numerous than the fertile seeds ; testa very hard, rather thick. 

 Wonderland Peak, Grampians, Victoria (P. R. H. St. John). 



E. diversifolia (santalifolia F.v.M.). 



" Sterile seeds broad, nearly as large as the fertile seeds. . . . Fertile, seeds few, sharply angular 

 and very slightly membranous at their edges. The approximate conformity of the fertile and sterile seeds 

 is that of the Renantherse or generality of Stringybark trees." (" Eucalyptographia," figs. 9 and 10.) 



Fertile seeds rather dull, light brown, 1^—2 mm. long, about' 1-| mm. broad, 

 angular-turbinate to somewhat D-shaped, usually much narrower towards the hilum, 

 and also more or less truncate, with two or three faint ridges, the edges sharp or rounded, 

 minutely pitted striate on the back. Hilum terminal, rather large ovate to orbicular, 

 usually paler than the thin, brittle testa. 



Sterile seeds glossy, light brown, often difficult to distinguish from the fertile 

 seeds, the majority, however, are usually more D-shaped, harder and more shining, 

 and with less marked ridges. 



Somewhat similar to E. patens, but without the prominent ridges, while a number 

 are more turbinate. Botanic Gardens, Sydney, cult. (W. F. Blakely, June, 1918). 



(c) Large and thick. 



Fertile seeds thick, 4-6 mm. long, 2-4 mm. broad, pyramidal to D-shaped, with 

 prominent, more or less muricate ridges. Hilum terminal, rather large. 



Sterile seeds pyramidal to D-shaped, smaller than the fertile seeds. 



E. Planchoniana. 

 E. megacarpa. 



E. Planclwniana. 



" Seeds without any appendage, the sterile not much smaller than the fertile seeds." (" Eucalypto- 

 graphia," figs. 9 and 10.) 



Fertile seeds dark brown to black, glossy, 5-6 mm. long, 3 mm. broad, 3-5 

 angled, more or less pyramidal in shape, with 3-5 ridges radiating from a broad,
