AFFINITIES. 



1. With E. incrassata Labill. 



It belongs to the incrassata series. E. incrassata is figured at Plate 13, Part IV, 

 but there is some doubt about the type of that species. The buds of E. incrassata are 

 more conoid than those of E. Comitce-Vallis ; larger, and with shorter and coarser 

 peduncles and pedicels. E. incrassata is, on the whole, a more coastal species. 



2 and 3. With E. dumosa A. Cunn., and E striaticalyx W. V. Fitzgerald. 



It is less closely allied to these species, which attain the dignity of trees, and 

 which differ in their striated opercula and other characters. 



C VII. E. longifolia Link and Otto. 



Proposed new variety, multiflora. 

 (For E. longifolia see Part XX, p. 295, Plate 86). 



We have a variety of Woolly-butt whose bark and timber are much the same as that 

 of normal Woolly-butt (E. longifolia). Both variety and normal form vary in the 

 bark, hence the names Peppermint and Grey Gum applied to both of them. 



At one time I looked upon the form (as regards the Erina Creek, Gosford, New 

 South Wales, specimens, which I constitute the type of the variety) as a hybrid of 

 E. longifolia, in which E. robusta Sm. (Swamp Mahogany) played a part. See Proc. 

 Linn. Soc. N.S.W., xxviii. 944, 1903, where I exhibited specimens before the Society; 

 Trans. Aust. Assoc. Adv. Science, 303, 1904; my " Forest Flora of New South Wales," 

 vol. ii, p. 186, and the present work, Part XX, p. 296, where I promised a figure (given 

 on Plate 239). It is a very interesting form of E. longifolia, with smaller fruits, seven 

 in the head, while those of E. longifolia are persistently in threes. 



What appears to be the same variety is a Grey Gum collected by Forest Guard 

 Gallagher in State Forest No. 423, Parish Nowra, county of St. Vincent, New South 

 Wales, on 20th June, 1919. The tree was about 4 miles from Nowra, at an elevation 

 above sea-level of about 100 feet. Complete material is unavailable, as the tree was 

 later " felled and utilised in connection with forestry improvement work." Its name 

 of Grey Gum indicates that local people are of opinion that the Nowra tree has affinity 

 with E. punctata DC, which indeed it has, but one cannot say more until additional 

 material becomes available.
