Under each species he usually briefly describes the seeds. As a rule he contents 

 himself with the statement that the fertile seeds are broader or larger than the sterile 

 ones. He usually figures the seeds, both fertile and sterile, and a number of these 

 drawings are most helpful. He is the only author who has done this, and it is a pity 

 he did not give full descriptions. The figures of the sterile seeds appear to have 

 but little value, since there are no characters to separate those of various species. 



Lubbock, in " A Contribution to our Knowledge of Seedlings," (1892), describes 

 the seeds of two species, E. globulus and E. stellulata. 



Professor R. Tate, in Rep. Aust. Ass. Adv. Science, vii, 551, (1898), remarks : — 



As pointed out by Bentham. the fertile seeds only differ from each other in being wingless or winged, 

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

 specimen." And though Baron F. v. Mifeller, in his " Euealyptographia/' has depicted the seeds (fertile 

 and sterile) for each, yet he does not utilise the apparent distinctions among the leading specific characters. 

 I, myself, have thought it not worth the while to test the value of this structure. 



Dr. Cuthbert Hall, Proc. Linn, Soc. s N.S.W. XXXIX ; 476 (1914), states:- 



Fruit generally many seeded, the majority, or all but one, being sterile. In the Corymbosse group, 

 of which E. corymhom may be taken as a type, there is generally only one fertile seed to each cell, and this 

 is vertically compressed and flattened from before backwards, the hilum showing as a paler depression 

 in the middle of the ventral surface, and the testa is frequently prolonged into a membranous appendage 

 to aid distribution by the wind. In E. corymbose/,, the posterior angle is keeled. In most of the other 

 Eucalvpts, the fertile seeds are more numerous, and are compressed and angled laterally, according to 

 their position in the cell : the hilum is at the narrower inner extremity, and the larger outer extremity 

 is rounded to the shape of the wall of the cell. The sterile seeds are light brown, narrow or linear, the 

 fertile ones dark brown or black.

2. -DANGER OF COLLECTING SEED OF INFERIOR SPECIES. 



In Part LXI, p. 30, of my " Forest Flora of New South Wales," are two 

 paragraphs, headed " Industry of Seed-collecting " and " Danger of Planting Inferior 

 Species," which are taken from my Presidential Address, Journ. Boy. Soc, N.S.W. , 

 XXXI, 51 (1897). To these I beg to refer my readers, for I have very definitely pointed 

 out the seriousnesss to the community of collecting and distributing inferior seed. 

 The trouble is a very old one, and is far from being stamped out even yet.
