Fl. mixta, (iOi, to B. vim'malis ; there has been some confusion of numbers here 

 which I do not jiretend to be able to unravel, and Avliich is of no particular 

 consequence. 



E. radiata, Sieb., appears to be nothing more or less than a form of 

 E. amygdalina very common in New South Wales, and I see nothing distinctive 

 enough to warrant its being called a variety. The typical amygdalina from Tasmania, 

 with its linear-lanceolate, often thickish, leaves, with hemispherical opercula and 

 hemispherical, usually broad-rimmed, fruit, doubtless appeared to Sieber to be 

 sufficiently different from the New South Wales form. Sieber's type probably came 

 from the higher parts of the Blue Mountains (I have matched it completely from 

 Wentworth Falls to Mount Victoria). Tt is also common in some northern localities. 

 The specimens distributed by Sieber have fruits not dead ripe ; when they are quite 

 ripe the tips of the valves are slightly exserted. 



Much Qonfusion lias gathered round E. radiata, Sieb. 



Hooker {Fl. Tas.) attributed four forms to E. radiata which I will, later on, 

 show to belong partly to E. Risdoni, Hook., f., var. data, Benth., and partly to 

 E. amygdalina, Labill. 



Then Bentham (B.El. iii, 203) described a var. radiata of E. amygdalina 

 which is a combination of {a) E radiata, Sieb., of {b) Hooker's Tasmanian supposed 

 forms of radiata, and of (c) the " White Gum " of Bent's Basin and the Nepean 

 River, N.S.W. (Woolls). The " White Gum " of Bent's Basin I will presently deal 

 with under the name umuerosa, var. of sp. nov. 



5. E. purpiirascens, Link. 



230. E. purpiirascens. Fol. amplexicaulibus lanceolatis longe acutatis subtus glaucis. Hab. in 

 Australia. Rami piirpurascentes. Folia 4' longa, 10" lata juniora subtus saltern nervis purpurascentia. — 

 (Link's Eniimcratio, p. ."51.) 



£. purpurageeiis (Link, Etmm. '2, p. 31), foliis oppositis amplexicaulibus lanceolatis l<inge acutis 

 subtus glaucis. In Nova Hollandia. Rami et nervi folioruni purpurascentes. Folia 4 poll, longa 10 lin. 

 lata. Foisan vat-ietatos 2 sequentes sunt tantum ejusdem fomife ut in E. ylauca diversissimie. Flores ign. 



Var. pciiulnld, foliis brcvitor petiolatis lineari lanceolatis acuminatis. — (DC. I'rod. iii, 2'2\.) 



I have seen the original specimen in the Prodromus herbarium. It bears the 

 label " E. pni'purascens. Link, Enum., Jard. de Berlin, M. Otto, 1826," and again, 

 " E. purpui'ascens. Link, \a,v. petiolata, DC. (DC. Prodr., n. 42)." It is in juvenile 

 foliage only, but I have no doubt that it is referable to E. amygdalina. E. purpm-ascens, 

 var. petioUiris, DC. is E. corymbosa , Sm. 



A specimen of E. purpuruscens. Link, in Herb. Vindob. is iu the ojjposite- 

 ieaved stage, and is probably E. amygdalina, Labill. The under side of the young 

 foliage of this species is often purple.
