Affinities.

1. E. stellulata, Sieb.

As already indicated, the closest relations of E. coriacea are with E. stellulata, of which, in some respects, it strongly resembles a coarse form.

2. E. coccifera, Hook. f.

It seems to me that the alpine forms of E. coccifera are very close to the Tasmanian E. coccifera, Hook. f., and this word of caution may be useful to the student.

3. E. vitrea, R. T. Baker, or E. vitellina, Naudin.

In a specimen from the Blue Mountains in Herb. F. Muell. the leaves are long and almost linear lanceolate, but very thick with the longitudinal veins of E. coriacea, of which it has also the flowers. —(B.Fl. iii, 201.)

In the above passage Bentham is doubtless speaking of specimens very similar to those I have from Jenolan Caves (W. F. Blakely). They are nearest to Mr. R. T. Baker's E. vitrea, though not typical. E. vitrea is, in my opinion, a hybrid between E. coriacea and E. amygdalina.

I will go into the matter at some length when dealing with E. amygdalina. Suffice it to say, at this place, that the tree referred to in the Flora Australiensis could not be confused, in the field, with E. coriacea; the former being a rough-barked tree and the latter a specially smooth gum.
