(6) Moderately large, triangular to compressed D-shaped. 



Fertile seeds light brown to jet black, 1 J— 3 nun. long, l|-2 mm. broad, compressed 

 D-shaped to somewhat pyramidal, with 1 to 3 more or less prominent ridges. Hilum 

 terminal, rather small. 



Sterile seeds somewhat triangular, oblong to compressed D-shaped, somewhat 

 similar to the fertile seeds.

E. Preissiana. 



" Most sterile seeds attaining nearly the size of the fertile seeds, all without any appendage. Majority 

 of seeds from, nearly 1 to 1-J lines long, none very narrow. The mutual similarity or even conformity of 

 the fertile and 'sterile seeds place E. Preissiana so far near the the Renantherfc, the broad sterile seeds 

 occurring in but very few species outside of that group." (" Eucalyptographia," figs. 10 and 11.) 



Fertile seeds dark brown, shiny, 3 mm. long, 2 mm. broad, compressed D-shaped, 

 with rather sharp edges, and somewhat obtuse ventral ridges, and slightly depressed 

 laterally, the surface somewhat pitted rugose, and darker than the margin, the inner 

 face rather straight, the back convexed. Hilum terminal, small, ovate, paler than the 

 somewhat thick testa. 



Sterile seeds glossy, pale to dark brown, 3-4 mm. long, 2 mm. broad, oblong- 

 D-shaped, somewhat similar to the fertile seeds ; testa thick and hard. 



It is very difficult to separate the fertile seeds from the sterile seeds, the latter 

 are sometimes much larger and paler than the former. Bremer Bay (J. Wellsteac 1 , 

 May, 1919). 



E. patens. 



" Fertile and sterile seeds of the same form and size, all compressed, mostly not much longer than 

 broad, none provided with a marginal membrane. Seeds measuring about 1 line in length." (" Eucalypto- 

 graphia," figs. 9 and 10.) 



Fertile seeds very pale to dark brown, 2 mm. long, 1 mm. broad, plump, angular 

 and D-shaped, the sides rather dull, the broad convex back smooth and glossy, the 

 inner face with one or two faint ridges, the margin firm and rather sharp. Hilum 

 terminal, small ; testa thin. 



Sterile seeds compressed, very glossy, light to dark-brown, D-shaped, the 

 majority slightly larger than the fertile seeds ; testa very hard. 6 miles from Busselton, 

 Western Australia (Percy Murphy, April, 1D09).
