whom we are indebted for them. The third, in which the hand- 

 kerchiefs of the party formed the background, is of a Mallee 

 {E. sp.) at Wyalong, for which we are Indebted to Mr. W. J. 

 Moffat, who also, most kindly, did his best to obtain seedlings 

 at Wyalong for us, and who sent us the Mallee-root figured. 

 The published illustrations of Mallees, that we have seen, fail to 

 give any idea of what is out of sight underground. 

 Angophoras. 



We have obtained good series of seedlings of four species, A. 

 cordi/'olia, A. r/ifermerlia, A. laiiceolata, and A. suhvelutina. 

 They are alike, in that they are somewhat refractory. The stem- 

 nodules are slow in appearing, that is the incubation-period is 

 longer than in the Eucalypts we know best. Some bush-seedlings 

 of a batch, that were over a year old, showed just recognisable 

 steni-nodules; but others showed nothing at all. Nevertheless, 

 when they are old enough, it would be surprising to find them 

 without some. The nodules are not only slow in appearing, but 

 they grow rather slowly after they do appear. Hence it is 

 common to find examples on which only the first pair have fused 

 (PL vi., fig.l); and one of these often grows more than the other, 

 so that the fusions are lopsided. Meantime, the internodes have 

 had time to lengthen,- so that, even if there were fusions of the 

 pairs above the first, there is little chance of concrescences. We 

 have some advanced seedlings, however, which show large and 

 complete tumours. Anomalies are common. We have one 

 seedling with six incomplete pairs, and nothing else. We have 

 not seen young root-nodules, like those figured in three Eucalypt 

 seedlings; and we have not seen later stages of them in Euca- 

 lypts. But we have examples of Angophora seedlings with what 

 appear to be late stages, unmistakably on the root, and incor- 

 porating roots. 



Though, in this paper, we are confining our attention to Euca- 

 lypts and Angophoras, we may just mention that we have speci- 

 mens of about ten species of other genera which appear to be 

 similarly afflicted. We have been able to get young stages, with 

 paired, a^^illary nodules, of some of them; but it is difiicult to 

 get young enough seedlings of the others. We hope to offer 

 some observations on these on another occasion.
