| Eucalyptus
perinniana (spinning gum) is a rare, distinctive
mallee-form eucalypt that in Tasmania only grows on
seasonally waterlogged areas on sandstone in the south-east
(it also occurs in the snow country of Victoria and NSW).
Its distinctive features are the very glaucous, sessile,
opposite leaves which are fused around the stem. The only
other species with the leaves fused around the stem is E. risdonii
and juvenile leaves of E.
tenuiramis, but the tips of the leaves of
those species are pointed, whereas E. perinniana
has blunt juvenile leaves. It flowers while still with
juvenile leaves and rarely has adult leaves in the wild.
