L ^ E. unialata. 



Fertile seeds dark brown, about 3 mm. long, 2 mm. broad, ovate to orbicular 

 in outline, more or less slightly rugose or muriculate, rather thin, the inner face with a 

 rather large, usually elongated depression surrounding the hilum, the back slightly 

 pitted rugose, the edge minutely fringed. Hilum ventral, and sometimes deeply 

 depressed, whitish, the testa very thin and firm. 



Sterile seeds red-brown, 1-2 mm. long, triangular, cmadrangular and awl-shaped, 

 the attachment scar central on the broad seeds and terminal or on the end of the narrow 

 seeds ; very numerous. The Domain, Hobart, Tasmania (L. Rodway, February, 

 1918). 



E. globulus. 



" Seed horizontal, flattened, compressed and angled laterally or dorsally into very various shares ; 

 testa deep brown or black; hilum ventral, paler in colour than the rest of the seed." " On Seedlings 

 (Lubbock, I, 530). 



" Seeds all without any appendage, the sterile much nar ower than the f rtile seeds." (" Eucalypto- 

 graphia," figs. 9 and 10). 



Contrasting the seeds of E. globulus and E. alpina, Mueller says : — , . 



"... the seeds of the two are visibly different, those of E. alpina being sharply angidar, more 

 shining and perceptibly wrinkled-streaked, while most of the sterile seeds are far less narrow ; thus fertile 

 seeds can be easily sifted from sterile seeds of E. globulus, whereas the separation of them in E. alpina would 

 by the sifting process be as difficult as in E. obliqua, E. macrorrhyncha, and many other species. . . 

 (" Eucalyptographia," under E. globulus.) 



Fertile seeds shiny, dark brown to black, 1-3 mm. long, 1-2 mm. broad, poly- 

 morphic, the majority somewhat compressed pyramidal to ovate, all more or less angular, 

 with 1-4 scarcely prominent radiating ridges extending from the hilum to the edge, 

 the back flattish, somewhat wrinkled, and with a few broad, shallow pits, the whole 

 surface covered with a minute, jet black, scurfy, deciduous substance, which is fringe- 

 like on the ribs and margins. Hilum ventral, large, much paler than the thin testa. 



Sterile seeds glossy, reddish-brown, the majority narrow, subulate to clavate, 

 more or less quadrangular, 2-4 mm. long, the broad ones shorter and more cubiform 

 to D-shaped. 



Differs from E. Maideni in being slightly larger, and in the longer sterile seeds. 

 Tumberumba (per Forestry Commission, September, 1918). 



E. Maideni. 



Fertile seeds shiny, dark brown to black, 1-2| mm. long, 1-2 mm. broad, poly- 

 morphic, somewhat angular, compressed pyramidal, ovate-oblong, with 1-5 slightly 

 raised radial ridges extending from the hilum to the edge, more or less wrinkled, or with
