Maiden, E. Deanei Maiden (Mr. A. Murphy informs me that there are plenty of trees 

 in the Ourimbah district, near Gosford, 1.0 to 12 feet in diameter), E. Dunnii Maiden 

 (see note below), E. diversicolor F.v.M. (see this work, Part XX, p. 298), E. gigantea 

 Hook. f. (see note below), E. Jacksoni Maiden, E. goniocalyx F.v.M., E. maculata 

 Hook., E. microcorys F.v.M., E. nitens Maiden, E. pilularis Sm. (see this work, Part L, 

 p. 30), E. regnans F.v.M., E. viminalis Labill. 



Under E. viminalis, Mueller (" Eucalyptographia ") quotes a Victorian tree 

 up to 320 feet, with a diameter of 17 feet. 



Baker and Smith (" Research on the Eucalypts," p. 137) say this tree is " probably 

 the largest of New South Wales Eucalypts." ' This is perhaps the most widely- 

 distributed species of the genus in these States, as well as probably the tallest, as trees 

 measuring over 300 feet high frequently occur." (p. 138.) 



In view of the fact that E, Dalrympleana has been " carved out " of E. viminalis, 

 and of further investigations in regard to our White Gums, it is desirable that E. viminalis 

 and its allies should be remeasured. E. viminalis, sensu strictu, is, however, undoubtedly 

 a big tree. 



E. Dunnii. — 



1 I measured one standing tree of the above, which gave a girth of 24 feet 4 inches, with a length 

 of at least 30 feet; this works out 13,3224 feet — superficial. The tree in question is fairly round and 

 straight, and apparently sound. A few days later, " To-day I measured another tree. It was felled for 

 sawmill purposes. It was perfectly sound, straight and round. This tree was cut into four logs 11 feet 

 in length (each log), the butt log measured 13 feet in circumference and contained 4,500 super, feet. 

 Royalty at 6d. (£1 2s. 6d.)." (William Dunn, Forest Guard, Acacia Creek, Macpherson Range, near 

 Queensland border, September, 1905.) 



E. gigantea. — I submit an interesting note based on observations made in Tasmania 

 in the thirties, and which I submitted to Mr. Rodway, the Government Botanist of 

 that State, who reports : ' In the Richmond district there is much E. obliqua and 

 E. gigantea. I have never seen the former of such gigantic proportions as cited, wherefore 

 think reference was to latter. At the time this article was written, all the forms with 

 rough bark were referred to obliqua, and those with smooth to amygdalina." 



Following is the note : — 



" Mr. Backhouse and my son, Dr. Joseph Hooker, have made MSS. remarks upon a great number 

 of new species in Van Dieman's Land, and it is there that the trees are seen to attain the most gigantic 

 size. Near Richmond, in Yorkshire, the former gentleman visited a place in the forest remarkable for an 

 assemblage of gigantic " stringybarks," Eucalyptus obliqua ? There, within a space of half a mile, he 

 measured ten different trees from 30 to 55 feet in circumference at four feet from the ground ; and some 

 of these - fine sound trees were upwards of 200 feet high. One prostrate tree was 35 feet in circumference 

 at the base, 22 feet at 66 feet up, 19 feet at 110 feet up. There were two large branches at 120 feet, and 

 the elevation of the tree, traceable by the branches on the ground, was 213 feet. ' We ascended this tree 

 on an inclined plane formed by one of its limbs, and walked four abreast with ease upon its trunk ! In its 

 fall it had overturned another 168 feet high, which had brought up with its roots a ball of earth 20 feet 

 across. It was so much imbedded in the earth that I could not get a string round it to measure its girth. 

 On our return I measured two stringybarks, near the houses on the Hampshire Hills, that had been felled 

 for splitting into rails, each 180 feet long. Near to them is a" tree that has been felled, which is so large
