CLX. E. amplifolia Naudin. 



I have shown, p. 20, Part. XXXI, Plate 131, that this species is a valid Australian 

 one. Dr. Trabut is under a misapprehension in looking upon it as a hybrid, 

 I continue the translation. 



In the Red Gum plantations one also finds, with an infinite number of forms of E. rostrata, some 

 tareticornis very polymorphous, and verging towards E. rostrata. Amongst tin's evidently hybrid descent 

 Naudin thought he could distinguish as a species a very fine tree which he has named E. amplifolia, and 

 of which the following are the characteristics : — 



E. amplifolia Naudin (PI. xiii). 



A strong tree with a smooth trunk; young leaves very large, oval, leaves of the adult tree oblique, 

 lanceolate, pointed or oval; floral umbels with long peduncles, from nine to fifteen flowers borne on 

 pedicels as long as the flowers; calyx-tube short, bearing a white operculum elongated into a long 

 attenuated rostrum, and twice the length of the calyx-tube; the outer stamens straight, the inner ones 

 with flexuose filaments; fruits spherical, capsule small, jutting out above the very thick calyx-tube; 

 opening by .three to four straight valves, seeds not very numerous. 



E. amplifolia varies greatly in its seeds. One can distinguish it from the E. tereticomis type by 

 its umbels with more numerous flowers, by the bud surmounted by a shorter operculum, contracted into 

 a beak. 



It is presumed that, by the constant action of hybridisation, it will become more and more difficult 

 to distinguish the primitive species comprised under the general denomination of Red Gum. 



E. rudis, rostrata, tereticomis, under the influence of cultivation, have given and will give new forms, 

 which are very interesting on account of their great vigour and perfect adaptation. For the 

 multiplication of these trees it is important to collect seeds from well-grown specimens, which are 

 generally hybrids. 



DESCRIPTION. 



CCXCJII. x E. antipolitensis Trabut. 



» 



Reputed parents, E. globulus L'Her., and E. viminalis Labill. 



In Proc. Roy. Soc, Tas., 1918, p. 89, I have stated that I look upon it as con- 

 specific with E. unialala Baker and Smith. I am of opinion that they both originally 

 arose from a cross or crosses between E. globulus and E. viminalis, but whether they 

 are really indentical I prefer to suspend my judgment. 



At tin- Vill.i Thurcl al Antibcs (Southern Fri I, where there is a collection of Eucalypts made 



Naudin, I hi ciallj observed .* verj fine abject, worthy of propagation, Naudin had 



provisionally labelled it !■',. viim longifolia. The examination "f the organs "f reproduction as 



of vegetation leave no doubf is to the pi ol fchi Form with /',' globulus. I propose to call it the 



Kii' alj plus.
