Fertile seeds glossy, light brown. 10-15 mm. long, including the wing, 4-6 mm. 

 broad, compressed, minutely wrinkled, acute or obtuse, the wing hyaline, oblique and 

 usually gradually diminishing towards the apex, minutely pitted on both sides. Hilum 

 ventral, ovate, small, usually closer to the lower edge of the endosperm than to the top ; 

 teste thin. 



Sterile seeds glossy, reddish, 6-10 mm. long, narrow, the broadest 2 mm. long, 

 somewhat soft and hyaline, and minutely pitted. 



Larger and more compressed than E. ferruginea- and also more compressed 

 than E. perfoliate/, with a different hilum. 



E. perfoliata. 



" Seeds not seen." (B.F1. III. 254.) 

 Fertile seeds glossy, light reddish brown. 10-15 mm. long, including the wing, 

 4-5 mm. broad, thickish, the wing sometimes slightly broader, in the middle very thin, 

 hyaline towards the tip, somewhat venulose, with moderately straight veins near the 

 base, the surface pitted rugose. Hilum ventral, closer to the lower edge of the endo- 

 sperm, rather large, ovate-oblong, 2-3 nun. long, testa thin, hard. 



Sterile seeds glossy, reddish brown, compressed, narrow, up to 5 mm. long. 

 E. ptychocarpa. 



; ' Seeds winged." (B.FL Ill, 255.) 



The fertile seeds produced into a rather large terminal appendage, the sterile seeds much narrower. 

 Fertile seeds about 2 lines long, with an almost oval appendage, extending additionally to 3 lines, the 

 appendage of the sterile seeds very narrow." ( iC Eucalyptographia," figs. 10 and 11.) 



Fertile seeds glossy, reddish brown, 10-14 mm. long, including the wing, 4-5 

 mm. broad, obtuse or acute, convex on both sides, and more or less wrinkled-rugose; 

 the oblique hyaline wing sometimes broader than the endosperm, usually obtuse, 

 minutely pitted on both sides. Hilum ventral, on the upper half of the endosperm, 

 rather large, usually ovate, paler than the hard thin testa. 



Sterile seeds glossy, reddish brown, very narrow, 5-10 mm. long. 



More compressed than E. Foelscheana., both in the endosperm and the wing, 

 and also with a more terminal hilum. 



E. Foelscheana. 



"Fertile seeds large, terminated by a conspicuous membrane; sterile seeds very slender." 

 (" Eucalyptographia," also figs. 9 and 10.) 



Fertile seeds glossy, reddish brown, 12-15 mm. long, including the wing, 4-5 

 mm. broad, compressed to somewhat triangular, plump, or with a prominent keel and 

 more or less rugose or wrinkled on both sides. Wing flat or concave, usually somewhat 

 pointed towards the hyaline apex. Hilum ventral, large, about the centre of the endo- 

 sperm; testa thin and hard. 



Sterile seeds glossy reddish brown, narrow, 4-6 mm. long, more or less compressed 

 and irregular in outline. 



Thicker and with a more concave wing than E.ficifolia.
