332 NOTES ON NATIVE FLORA OF NEW SOUTH WALES, VIL, 



edges of the leaves can be seen, resembling circular blades. 

 The foliage, which is exceedingly rich in eucaljptol, loses the 

 white powder with maturity, and when, by contact with adjoining 

 trees, it is rubbed off the young leaves, these present a bright 

 rich green appearance, especially if in shadow. Another curious 

 feature is that the leaves through being sessile, cordate and 

 opposite, imprint circular marks on the branches and stems, 

 which remain for several years after the leaves have fallen, but 

 disappear when the bark is sited at the end of about four years. 

 That the species is rare, is shown by the fact that, after Cunning- 

 ham found it in 1822, it was not again collected till a very small 

 patch of it was noticed by me in 1900, at Cow Flat, near 

 Bathurst, on micaceous schist-formation. A third locality, on 

 Silurian slate-formation, viz., Cowra Creek, near Cooma, is 

 now added, after a further lapse of eight year.s, or 86 years 

 since Cunningham's discovery. 



In October, 1904, I visited Cox's River, in company' with Mr. 

 J. H. Maiden, for the purpose of ascertaining whether any plants 

 of E. pulvigerCi remained, and we found a considerable quantity 

 extending from the top of Mount Blaxland (where Cunningham 

 probably collected it, 82 years before) across to the northern side 

 of Cox's River, and on the roadside leading from Bowenfels to 

 the river, growing on aplitic granite-formation. 



After referring to the differences and close affinities between 

 E. pulvigera and E. cordata, in these Proceedings for 1902, I 

 was disposed to regard one as a variety of the other, thinking 

 that possibly a connecting link would be found in some locality 

 between Bathurst and Tasmania, where a plant showing grada- 

 tions to both might be discovered. The surmise is partl}^ borne 

 out by the discovery of E. pulvigera near Cooma, some 200 miles 

 south of Bathurst, hut after examination, the specimens are found 

 to be practically identical with the Bathurst and Cox's River 

 forms, so that there seems no reason why E. j^ulvigera f«hould not 

 have specific rank. At the same time it is highly probable that 

 both had a common origin, and have developed differences owing 

 to environment, extending over long ages. Both are rare,
