Fertile seeds red brown, about 4 mm. long, 4 mm. broad, thin, ovate to scuti- 

 form, more or less muricate, the margin sometimes very thin or membranous, the back 

 microscopically pitted. Hilum ventral, ovate to orbicular, rather small. Sterile seeds 

 not seen. 



E. papuana. 



Fertile seeds light brown, 5 mm. long, 3 mm. broad, thin, ovate to scutiform, 

 more or less rugose, the inner face microscopically reticulate. Hilum ventral, orbicular, 

 rather large. 



Sterile seeds light brown, about 1 mm. long, cubiform. 



E. clavigera. 

 " Seeds without any appendage." (" Eucalyptographia," figs. 9 and 10.) 



Series Kochioides. 

 Fertile seeds light to dark brown, 4-5 mm. long, the majority with a distinct 

 •narrow, circular, marginal membranous wing surrounding the endosperm, and usually 

 with 3-5 more or less prominent radial ridges on the ventral surface. Hilum ventral. 



Sterile seeds dark to reddish brown, cubiform, subulate to clavate, smaller than 

 the fertile seeds, except a few in E. macrocarpa, which are considerably longer.

E. pynformis. E. angulosa. 



E. macrocarpa. 



" Fertile seeds much larger than the partly very narrow sterile seeds, and edged by a broadish marginal 

 membrane. . . . Fertile seeds radiating-angular from the hilum to the membranous margin, the whole 

 measuring 2-3 lines, some of the sterile seeds quite as long or even longer, but remarkably slender." 

 ( (i Eucalyptographia.") 



Fertile seeds light brown, 4-5 mm. long, about 4 mm. broad, ovate to somewhat 

 pyramidal or conical, surrounded by a thin, more or less reticulate membrane, about 

 1 mm. broad, or sometimes broader on the end of the seed, and with two or more short, 

 narrow, radial ridges extending from the hilum to the outer membrane. Hilum ventral, 

 very small, and partly hidden by the thin radial ridges, dark or light coloured. 



Sterile seeds of two types, one awl-shaped to clavate, 5-10 mm. long, and the 

 other in short irregular cubes 3-4 mm. long and about 2 mm. broad, both kinds are of 

 a reddish -brown colour, with the scar of attachment rather conspicuous on one end. 



E. pyriformis. 



" Fertile seeds much larger than the partly very narrow sterile seeds, and edged by a broadish 

 marginal membrane. . . . Fertile seeds generally li-lj lines long, with radiating angles from the 

 hilum. Sterile seeds very much narrower, though many of them not shorter." (" Eucalyptographia.") 



[In some rather poor seeds of var. Kingsmilli there is a narrow, rather 

 inconspicuous margin.]
