Fertile seeds glossy, light brown, 4-5 mm. long, 3-4 mm. broad, somewhat 

 triangular to D-shapcd ; the testa expanded circumferentially into a narrow hyaline, 

 concave wing, and supported on the ventral side by three or four prominent spreading 

 nerves, and sometimes with a distant intramarginal nerve, the dorsal convex, smooth 

 or slightly wrinkled. Hilum terminal, situated on a very narrow ridge, paler than the 

 thin, brown testa. 



Sterile seeds glossy, light to dark brown, polymorphic, all angular, the narrow 

 ones compressed clavatc, the broad ones D-shaped, without wings, flat or concave on one 

 s ; de, and usually with a moderately broad convexed back, the largest 5 mm. long, 

 3-4 mm. broad. The sterile seeds are much more numerous than the fertile seeds. 



Differing from E. pachyloma in the broader and more circumferential nerved 

 wing; narrower hilum and larger seed. Perth, Western Australia (Dr. J. B. Cleland). 



Series Muricatae. 



Fertile seeds glossy, jet black, 5-7 mm. long, elongated, pyramidal to triangular, 

 with 3-5 prominent radiating ridges extending from the conspicuous terminal hilum; 

 the testa muricate. 



Sterile seeds polymorphic, all somewhat obtusely angled and finely striate, the 



broad ones oblong-D-shapcd. 



E. sepulcralis. 



E. sepulcralis. 



" Fertile and sterile seeds of nearly the same size, very angular, without any membranous appendage. 

 Seeds not numerous in each cell, mostly from 1-J-- 2 lines in length, a few scarcely 1 line long; the fertile 

 seeds outside black, shining and marked with exceedingly subtle reticulation, the prominent angles 

 ascending and diverging from the hilum, the summit convex and broad; sterile seeds brown, narrower, 

 but never- very tlender." (" Eucalyptographia," figs. 9 and 10.) 



Fertile seeds jet black, glossy, 5-7 mm. long, 4-5 mm. broad, elongated pyramidal 

 to somewhat triangular, with 3-5 prominent undulating radiating ridges extending 

 from the hilum to the broken and somewhat membranous margin, the inner face 

 distinctly muricate, the back convex, minutely rugose. Hilum terminal, rather large, 

 usually with a broad, oblique depression sloping towards the back, whitish and very 

 distinct from the dark, rugose, muricate, hard testa. 



Sterile seeds glossy, light brown, 4-5 mm. long, narrow to broad, all more or less 

 obtusely angled and very finely striate, the broad ones somewhat D-shaped to 

 cubiform. 



It approaches E. pachyloma somewhat in the rudimentary membrane to the 

 fertile seeds, and E. ouprestium in the sterile seeds. Bremer Bay, Western Australia 

 (J. Wellstcad, December, 1919).
