 thin, often over in. long; 

 allel and very diverging: um- 

 large; calyx- lid about as long 

 as the tube (not exceeding 2 lines long): fr. 3 to 4 

 lines in diameter; valves level with or hardly project- 

 ing beyond the rim. Said to be near F. crebra, differing 

 mainly in the large flowers and in the larger, harder 

 and more globular fruit. 



Var. leptophlSba, Luehm. (E. leptophleba, F.v.M.), 

 is said to be chiefly distinguished by the Ivs. being 

 thicker and the veins more oblique. Timber strong, 

 hard and very durable ; used for bridges, mine props 

 and fence posts.

 bees. Dec.-Feb. F.v.M. Eucal. 7:8. -Timber remark-
