Following are specimens arranged according to localities : — 



Western localities. — " A Mountain Ash." Adelina Falls, Lawson (R. T. Baker 

 and H. G. Smith, April, 1899). The type. Mature leaves and immature fruits, which 

 1 was a long time in identifying with the Mount Wilson material I had collected three 

 years previously. Sucker leaves were collected by W. Baeuerlen from the same place 

 during the following month. 



Natural seedlings, Leura (R. H, Cambage and J.H.M.). 



Natural seedlings, plump buds and flowers. Blackheath (J.H.M.). 



Mount Victoria (J. L. Boorman, myself and others, but mostly with unripe 

 fruits). 



Glaucous sucker leaves. Mt. Victoria and road to Jenolan Caves (R. H. Cambage, 

 quoted in original description). 



Mount Wilson. The type of E. Luehmanniana var. altior. (J.H.M., April, 

 189C.) 



" Blackbutt," unripe fruits only available. Near Wolgan River (H,enry Deane), 

 Clarence to Wolgan (J. L. Boorman). 



Southern localities. — Hill Top, in deep gullies (E. Cheel). 



Northern localities. — Mt. Warning, near Murwillumbah, Tweed River, at 3,300 

 feet. A tree of 30-40 feet (W. Forsyth). Not to be distinguished from the type 

 specimens of E. Luehmanniana var. altior from Mt. Wilson. 



AFFINITIES. 



l. With E. Sieberiana F.v.M. 



This tree is allied to E. Sieberiana F.v.M., in the venation and shape of the leaves and nature of 

 timber, but it differs from it in its smooth bark and shape of fruits. . . . 



If it were not for the fruits and buds, it might be regarded as a smooth-barked variety of E. Sieberiana 

 F.v.M. ; but this cortical variation has now been shown to have very little to support it in the field, taken 

 in conjunction with other features. (Original description.) 



The Blue Mountains tree is known and cut commercially as " Mountain Ash." This is, of course, 

 the ordinary name of E. Sieberiana F.v.M. The timbers of the two trees are not dissimilar, neither are 

 the immature fruits (Dc?ane and Maiden, he. tit.). At Mount Irvine it is known as " Yellow Gum." (Forest 

 Flora, xxvi, 101.) 



There is undoubtedly a good deal of similarity between the half-ripened fruits 

 of E. oreades and those of E. Sieberiana, sufficient, at least, to put one on one's guard, 

 but the ripe fruits of E. oreades are very different.
