EUCALYPTUS FLORA. 357 
specimens vary somewhat amongst themselves, adding to 
the difficulty of determining some of them. 
None of the specimens are true H#. radiata, Sieb., which 
is found in New South Wales and Victoria; I have not 
seen it yet from Tasmania. 
Hooker (loc. cit.) attempted to define, and distributed, 
five varieties of ““Z. radiata, Sieb.,’ from Tasmania. I have 
examined a number of specimens from various herbaria, 
and report as follows upon them. 
Var. 1.—1073, Gunn. Twig taken from a young tree or 
young growth, the leaves not ceasing to be opposite; later 
on they will lengthen and narrow. From Herb. Benth. 
(Kew.) in Herb. Syd. It is 2. amygdalina, Labill. 
Var. 2.—Herb. Calcutta, ex Herb. Hook. (Kew.). 
There are two specimens on one sheet, both Coll. R. Gunn. 
(a) One is labellel “Hucalyptus radiata, Sieb., var. 2.” 
(6) Is labelled “ Hucalyptus radiata, Sieb., var. nitida.” 
(a) is in fruit only, and (6) is in bud only. (qa) is £. 
Risdoni, Hook. f., var. elata, and (0) is not to be distin- 
guished from the dull-leaved form referred to under var. 5, 
and is therefore #. amygdalina, Labill., var. nitida. 1112 
R. Gunn is also typical of var. 2. It is entirely identical 
with #. tenwiramis, Miq. It is non-glaucous, and may be 
referred to H. Risdoni, var. elata, or may be looked upon 
as a form of #. amygdalina, near to var. nitida, at the 
option of botanists; for, indeed, while close to the former, 
it partakes of the character of the latter, more particularly 
in regard to the leaves. 
Other specimens of var. 2, from Herb. Cant. and else- 
where, differ slightly from some of the specimens already 
referred to. I find that I cannot always separate vars. 2 and 
5, and therefore label them (including 1112 Gunn)—“ Z. 
amygdalina, Labill., tending to #. Risdom, var. elata.” 
One of Gunn’s 1112 is identical with #. fenwiramis, Mig. 
Var. 3—The only absolutely authentic specimen of this 
variety I have seen is ex. Herb. Hook., in Herb. Calcutta, 
and bears the usual litho. label, ‘‘ Hab. Tasmania, Coll. R. 
C. Gunn,” and the writing “ Hucalyptus radiata, Sieb., 
var.3” It isinvery young bud, but comparison withalarge 
series of specimens enables me to make the following 
statement. It is near var. 1, but more glaucous. It 
belongs to that series connecting H. amygdalina, Labill., 
var. alpina, and EH. Risdoni, var. elata, and different 
Eucalyptologists would put in one or the other, or both.
