EUCALYPTUS FLORA. 361 
sessile opposite leaves occupy frequently the flowering 
branches of #. Risdoni, and are only on the saplings and 
adventitious flowerless branches of H#. amygdalina; they 
are, moreover, broad, frequently connate, and usually 
glaucous or nearly white in the former, always, as far as 
known, narrow-ovate or oblong-lanceolate in #. amygdalina. 
When the leaves are alternate, they appear to be broader 
in #. Risdon than in EL. amygdalina, the pedicels thicker 
and more angular, the flowers and fruits larger, differences, 
however, of degree only, to which our dried specimens 
do not admit of our fixing any precise limits, and in that 
state it is sometimes scarcely possible to decide to which 
species they should be referred. ‘ 
“Var. elata.—A beautiful tree of the largest size, the 
bark of the trunk grey and deciduous, that of the 
extremities of the branches purplish red or reddish brown 
(Gum). Leaves broadly lanceolate-faleate, 2 to 4 in. long, 
rather thick, sometimes almost as in #. obliqua. Flowers 
of H. Risdon. Fruit pear-shaped, 4 lines diameter, with a 
broad convex rim.—Lake St. Clair (Gunn). This variety 
in the dried specimens appears to connect #. amygdalina 
with Z. obliqua, but without doubt belongs to #. Risdoni 
as observed by Oldfield, although the dried specimens were 
included by J. D. Hooker among the varieties of Z£. 
radiata, Sieb., now united to #. amygdalina.” (B. Fi. iii. 
203.) 
Var. elata is a drooping broad-leaved glaucous form, with 
broadish sucker-leaves, common (Mr. Rodway states) in 
mudstone country, in Tasmania, and one of the intervening 
forms between H. amygdalina and EF. Risdon. Has large 
domed fruits and coriaceous leaves, which are often 
glaucous along the edges, giving them an unusal hoar-frost 
appearance. They may be looked upon as having affinity 
on the one hand with 2. amygdalina, var. nitida, and on 
the other with var. alpina. 
The variety elata also closely approximates to EH. coc- 
cifera. 
Lanceolate leaves are common on the tops of branches 
of #. Risdon, it being not an uncommon occurrence to find 
the sessile, almost cordate leaves, and the lanceolate leaves 
on the same branch. I believe Mr. F. Abbott first made 
this observation, and he directed my attention to the trees. 
Mr. Deane and I made a similar observation in regard to 
#. pulverulenta, leaves of the two shapes being found on the 
same twig. (See Proc. Linn. Soc. N.S.W. 1900, p. 110.)
