E. terminalis. 



" Seeds with a rather long wing." (B.Fl. Ill, 257.) 

 Fertile seeds slightly glossy, light reddish brown, 10-14 mm. long, including 

 the wing, 4-5 mm. broad, somewhat plump, wrinkled, and minutely pitted, obtuse or 

 acute, the wing rarely broader than the endosperm, usually obtuse, hyaline and 

 transparent, about the same length as the endosperm. Hilum ventral, rather large, 

 usually inserted about the centre of the endosperm ; testa thin, brittle. 



Sterile seeds glossy, light reddish brown, compressed, narrow, 4-7 mm. long, 

 |-1| mm. broad, very thin, scale-like to hyaline. 



I have not seen the seeds of the following species : — 



E. Abergiana. 

 E. Cliftoniana. 

 E. pyrophora. 



E. Abergiana. 



" Fertile seeds expanding from their summit into a long membrane, much longer than the slender 

 sterile seeds. . . . very compressed, terminated by a semi-oval membrane, giving a length of about 

 J inch for the whole seed, including the appendage." (" Eucalyptographia.") 



Figs. 6 and 7 of that work show the seed terminated by a long membrane about as long as the seed. 



E. Cliftoniana. 



" Fertile seeds brown, terminating in a membranous wing; barren seeds wingless, small and narrow. 

 . . . Fertile seeds 2 lines long, the wings 3 lines in length." (Original description.) 



E. pyrophora. 



" Seeds apparently winged, but not seen perfect." (B.Fl. Ill, 258.) 



At B. Fl. Ill, 188, Bentham makes the following observations on the seeds of 



the Corymbosse at the conclusion of some notes on the genus : — 



" The most remarkable are those of the majority of the Corymbosse, which are large and more or 

 less expanded into a membranous wing; but even that character would appear to be of little value if we 

 consider that species so closely allied in every other respect as E. calophylla and E. ficifolia, or E. citriodora 

 and E. corymbosa, only differ from each other in their wingless or winged seeds ; that even this difference 

 is proved only by the examination of seeds most probably derived from a single tree of each, and that the 

 wing, when it exists, varies remarkably in size and shape in different seeds from the same specimen." 



" Subseries VIII.— Cory mbosae." 



" Seeds usually large, flat, with acute edges, often more or less expanded in a variously shaped 

 wing." (B.Fl. Ill, 253.)
