NOTES ON EUCALYPTUS. 431 
Juvenile leaves perfoliate. 
It is no doubt often passed over as a small E. coriacea, 
A. Cunn., var. alpina, but the perfoliate juvenile leaves 
and the mature leaves at once separate them. 
* *K * * * **k 
As regards the leaf-base we have various stages of (1) 
the auriculate, and (2) amplexicaul, through the (3) connate 
to the (4) absolutely perfoliate. 
All four forms are seen in EH. Perriniana, and the first 
two forms in EH. Gunnii, Hook. f. It remains to be seen if 
the last two forms (8) and (4) do not occur in EH. Gunnii. 
So far I am not always able to separate specimens of H. 
Perriniana showing only (1) and (2) from HE. Gunnii, but 
the immature bud of EH. Gunnii has a peculiarly pointed 
operculum, and the line of demarcation with the calyx- 
tube.a raised rim. The fruit of H. Perriniana appears to 
be smaller as arule, and uniformly more hemispherical, 
and the rim thinner than that of H. Gunnii. 
Figure 11, Plate 83 of my Critical Revision of the genus 
Kucalyptus exhibits the perfoliate leaves of H. Perriniana 
and not of EH. cordataas stated. Therecord of the locality 
should be near Hamilton, Tasmania. Mr. L. Rodway 
informs me he was with the late Mr. R. D. Fitzgerald 
when he collected it. 
5. HUCALYPTUS MEGACARPA, F.v.M. 
The pileiform operculum of EH. gomphocephala is unique 
in the genus; the same character, to a greatly diminished 
extent, is evident, especially in drying, in EH. megacarpa, 
and may indicate relationship to a species (gomphocephala) 
which has few recorded affinities. 
The affinity of the two species has been suggested before, 
but not as regards this organ.
