E. latifolia. 



" Seeds winged." (B.Fl III, 255,) 

 Fertile seeds gloss)', pale brown, 5-7 mm. long, including the short wing, 3-4 mm, 

 broad, rather thick, obtuse, more or less keeled, and wrinkled on the back and sides, 

 the wing small, usually concave near the endosperm, minutely pitted. Hilum ventral, 

 usually about the centre of the endosperm, very small and narrow, testa thin. 



Sterile seeds glossy, light reddish brown, compressed and hyaline, the narrow 

 ones up to 5 mm. long, the broad ones sometimes 4 mm. long, 2 mm. broad. 



Smaller and with a more lateral hilum than E.ferruginea. 

 E. ferruginea. 



" Seeds winged." (B.Fl. Ill, 254.) 



Fertile seeds (not seen ripe) glossy light brown, 8 to 10 mm. long, including the 

 wing, 4 mm. broad, rounded or obtuse at the end, with a few irregular veins or ridges, 

 the wing broad, rather oblique and usually turned upwards, very hyaline towards the 

 top, the surface minutely pitted rugose. Hilum ventral, somewhat semi-terminal 

 owing to the incurving of the top of the seed, small, testa thin, hard. 



Sterile seeds glossy, light brown, 4-6 mm. long, the broadest rarely exceeding 

 1 mm., all more or less curved, compressed and somewhat hyaline. 



Smaller than E. perfoliate/,, and with a more terminal hilum. 

 E. diehromopMoia. 



" Perfect seeds broadly winged on one side." (B.Fl. Ill, 257.) 

 Fertile seeds slightly glossy, light reddish brown, 8-12 mm. long, including the 

 oblique, transparent wing, 2-3 mm. broad, the wing slightly broader and longer than 

 the wrinkled endosperm; it is also more or less concave at its junction with the 

 endosperm. Hilum ventral, usually somewhat distant from the edge, and on a level 

 with the basal edge of the wing ; testa thin and firm. Endosperm moderately hard. 



Sterile seeds glossy, light reddish brown, compressed, narrow, 3-7 mm. long, 

 •|-1 mm. broad, scale-like to somewhat hyaline. 



Smaller and slightly more concave than E. terminaiis. 



E. ficifolia. 



" Fertile seeds greyish-brown, with long wings in the fore part, most of the seeds sterile, narrow 

 and elongated." (Original description.) 



"... differ in no respect from E.'calophylla, except that the seeds are of a pale colour, and the 

 testa expanded at one end, or round one side into a broad, variously shaped wing. Further specimens 

 may prove these differences not to be constant." (B.Fl. Ill, 256.) 



Fertile seeds pale brown, terminated by a long membranous appendage, much larger than the 

 mostly narrow sterile seeds." (" Eucalyptographia," figs. 9 and 10.)
