12. -SIZE. 



The fertile seeds of the various species differ in size from \ to 16 mm. long, and 

 from \ to 7 mm. broad. Those of E. dealbata are found to measure \ to 1 mm. long, 

 and \ to | mm. broad. The seeds of E. calophylla measure 5 to 16 mm. long, and 

 5-7 mm. broad. 



So far there have been observed ten species with seeds not exceeding 1 mm. in 

 length. No less than 90 species possess seeds over 1 mm. long, but not exceeding 2 mm. 

 in length. The vast majority of the fertile seeds have no wing or appendage, and a 

 large percentage of them are so small, and may be distributed by the wind, like dust 

 or fine sand. 



The non-winged seeds, 3 mm. and over, are less liable to be disseminated by 

 wind (strong gales excepted) than those considerably smaller. In any case, it is safe 

 to say that as all the seeds are comparatively light, they may at various times be 

 conveyed long distances by the wind from the parent tree. Or they may also be washed 

 away by local streamlets and flood water. 



In nearly all cases the majority of the fertile seeds are larger (sometimes several 

 times larger) than the sterile seeds. 



In some species the seeds may be said to be large for the size of the capsule, 

 for example, E. microtheca and E. Macarthuri. The capsules of the former are 3 to 

 4 mm. long and about as broad, while the seeds are from 1^ to 2\ mm. long, and 1 mm. 

 broad. The capsules of E. Macarthuri measure 4 to 5 mm. long, and 4 to 5 mm. broad, 

 and the seeds vary from \\ to 2 mm. long, and 1 to 2 mm. broad. When compared 

 with a large-fruited species such as E. pyriformis, the capsule of which measures 50 mm 

 long and 65 mm. broad, with the seeds 3 to 4 mm. long and 3 mm. broad, the comparison 

 is a remarkable one. Or take another large-fruited species, i.e., E. macrocarpa, whose 

 capsule measures 35 mm. by 70 mm., and the seeds are 4 to 5 mm. long and 3 mm. 

 broad. In the cases of E. microtheca and E. Macarthuri, the percentage of fertile seeds 

 to the cell would be found to be much smaller than that of E. pyriformis and 

 E. macrocarpa.
