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.
