I have similar sj)ecimens (in fruit only) from a Stringybark forest 15 miles 

 north-west of Mount G-ambier, South Australia. 



I have tested all the following points as regards E. vitrea, — viz., its sucker 

 foliage (medium lanceolate, dull, even glaucous) ; mature foliage (thickish, shining, 

 straight-veined, veins prominent, tips hooked) ; buds (operculum pointed, pale 

 brown, shiny) ; fruits (pale brown, rim well-defined and reddish-brown, shape 

 and size) ; bark (hard scaly, sub-fibrous, and smooth branches) ; timber and oil ; 

 and its characters are possessed in about equal proportions by E. coriacea and 

 E. amygdaUna. 



I think I have produced sufficient evidence (and more will be forthcoming 

 as soon as field botanists inquire with an open mind into the hybridisation question) 

 to show that my suggestion as to the hybrid character of E. vitrea is a very 

 reasonable one. That hybridisation occurs in the genus, and that there is much 

 evidence of it, I consider to be absolutely proved. 



Some illustrations of E. vitrea will be given in the next Part, which deals 

 (inter alia) with E. regnans. 



3. With E. regnans, F.v.M. This will be more conveniently gone into when 

 E. regnans is reached.
