106 A CONTRIBUTION TO, ETC. 



they may have supposed that the young tree, with its ovate or 

 conuate leaves, is not identical with the more advanced tree with 

 its stalked and lanceolate leaves. With the exception of the 

 gigantic "messmate," which belongs to the Mittagong Range, I 

 remarked near Berrima a scrubby Eucalyptus, similar to that on 

 the Blue Mountains. This I believe to be Cunningham's E. 

 microphylla. Not far from the place where I noticed it, the pow- 

 dery-leaved tree, called the " Argyle apple," was plentiful. There 

 can be but little doubt that this is E. pulverulenta It generally 

 appears on rocky places, and never attains any great size. The 

 tree has some resemblance to the apple of these parts (Angoplwra 

 intermedia), but the leaves are much more glaucous. The Camden 

 woolly -but which is so common near Berrima, appears to me to 

 be E. cUversifolia, for the leaves are sometimes opposite and some- 

 times alternate, varying in shape from ovate sessile to narrow 

 lanceolate. This is a large tree, very like the woolly-but of the 

 county of Cumberland in appearance, but the leaves are frequently 

 opposite, and the upper branches smooth : the seed vessels also 

 differ materially. Some time since I was under the impression 

 that our woolly-but w^as E. gomphocephala, but my learned friend 

 Dr. F. Mueller assures me that that species is restricted to another 

 part of Australia. The mountain ash I find to be E. mrgata, 

 a species not found near Sydney. Influenced by the difference 

 of soil and climate, this useful gum attains a great size, 

 and the wood is very serviceable, being used for shafts, 

 fencing, and other purposes. The bark of this tree is fibrous 

 in the lower part, but the branches are smooth, so that in 

 character and appearance it bears a resemblance to our black- 

 but (E. pilularis). One of the species, which is generally 

 found in low flats, is called " the Lead-coloured" or Water Grum," 

 and seldom exceeds thirty feet. It is a well marked species, 

 having the bark wrinkled below, but the greater part of the tree 

 perfectly smooth and of a lead colour. The wood is not much 

 valued. When 1 first saw this gum I regarded it as a new 

 species, and suggested to Dr. F. Mueller that it might appro- 

 priately be named in honour of my worthy friend the Rev. James 

 Hassall, of Berrima, who possessing a thorough knowledge of the 

 district in which he resides, takes a pleasure in conducting his 

 friends through the wildest and most intricate parts of the bush
