not come out very well in the photograph. The nodules of the 

 lowest pair furnish a good example of unequal progress. 



The remarkable seedling in Plate x., fig.«, has eight pairs; the 

 seventh and eighth are indicated, but had not completed their 

 growth when the specimen was secured. This was a pot-seed- 

 ling, about 2 feet high, and somewhat older than the others 

 shown in Plates ix. and x. It is the most remarkable, refractory 

 seedling we have seen. 



The remarkable seedling of E. euyenioides, about 4 feet high, 

 shown in Plate xix., has twenty nodules (possibly twenty-two), 

 fourteen stem-nodules, in addition to the concrescence, compris- 

 ing at least three pairs (possibly even four): four pairs are in- 

 complete, one nodule of each having failed to develop — potenti- 

 ally about twelve pairs. The nodule marked 1 is solitary, and 

 was about to fuse with the concrescence. The rest were not 

 likely to have accomplished anything whatever, even in the way 

 of fused pairs. Another, fine, but much younger specimen of 

 the same species, about 2 feet high, has twelve pairs, but the 

 uppermost are not very far advanced, and there are indications 

 of some others to follow; the first three pairs have nearly com- 

 pleted their concrescence. This specimen was obtained too late 

 to be included in the series shown in Plate vii. For its total 

 number of complete pairs, this is the most remarkable seedling 

 we have seen. 



Sometimes, but rarely, an extra nodule makes its appearance, 

 so that instead of the first pair, there is a whorl of three. When 

 this happens, the second node may, or may not, also show a whorl 

 of three. We have four seedlings, two of which show one whorl 

 of three; and two have two whorls of three. 'J he explanation 

 of this condition is that the cotyledons of both Eucalypts and 

 Angophoras occasionally show anomalies, such as three cotyle- 

 dons, fused cotyledons, or with one cotyledon partially or com- 

 pletely "split." When this happens, the first pair of leaves may 

 be normal, or dislocated, or replaced by a whorl of three leaves. 

 The significance of these anomalies, for our purpose, is the pro- 

 vision of an additional one or two axils for the collection of soil 

 or dust; or the loss of an axil.
