AFFINITIES. 



At pages C6 and 67 I have already gone into the relations of E. concolor to 

 E. decifiens, E. uncinata and E. falcata, and I have little to add. 



1. With E. deeipiens Endl. 



Dr. Stoward, under No. 122, sent me a specimen of " White Gum, height 30-40, 

 diameter of trunk 15-18 inches. Grows on limestone country in the Tuart belt along 

 the coast. Spot near Newmarket Hotel, Coogee Road. April-May, 1917." This is 

 from the neighbourhood of typical E. concolor, and although these specimens lack 

 juvenile leaves, they seem to answer to the description of E. deeipiens. If E. concolor, 

 as I surmise, then the tree is the largest recorded for that species. 



2. With E. uncinata Turcz. 



For this species I would invite attention to Plate 62, Part XIV, and would say 

 that the species is, as regards some of the Western Australian specimens; under 

 revision. 



3. With E. falcata Turcz. var. ecostata Maiden. 

 For this species see Plate 68, Part XV. 



Explanation of Plates (172-5). 

 PLATE 172. 



E. eximia Schauer. 



la. Peltate juvenile leaf, with curved venation; 1&, peltate juvenile leaf, the venation advanced a stage 

 towards the pinnate; Ic, intermediate leaf, the venation still further advanced, but not 

 yet completely pinnate, as the mature leaf depicted at fig. 1, Plate 173. Glenbrook, Blue 

 Mountains, N.S.W. (J.H.M.) 



2. Broad, short, intermediate leaf, not in the juvenile stage. Note the glandular appearance of the 

 young shoots. Springwood, Blue Mountains. (J. L. Boorman.) 



3a. Elongated petiolate juvenile leaf; 3&, 3c, 3d, different shapes and sizes of juvenile leaVes, all with 

 auriculate bases. 3d is almost hastate in shape. The secondary veins of 3c and 3d at a smaller 

 angle to the midrib than those of 3a and 36. These specimens are accompanied, at the lower 

 parts of the branchlets, by small, early leaves, arrested in their growth, similar in shape, and 

 only differing from the other leaves in size. These remarks apply to other species also. Hornsby 

 Valley, Galston Eoad, Sydney district. (W. F. Blakely.) 



4. Buds showing shrinking of the calyx-tube in drying and thus the operculum takes on a mushroom 

 shape. Cultivated plant. Inner Domain, Sydney. (J.H.M.) 



Compare E. Walsoniana, fig. 1/*, Plate 174.
