Eucalyptus viminalis, commonly known as Manna Gum, White Gum, Viminalis or Ribbon Gum, is native to south east Australia. It was introduced into the UK in 1885. It is currently used for small scale forestry production in Ireland. There are three sub species of this tree E. viminalis Subsp. viminalis, E. viminalis Subsp. cygnetensis and E. viminalis Subsp. pryoriana.

The etymological root of the binomial name Eucalyptus is derived from the Greek eu ‘good‘ and kalyptos ’covered’ referring to the calyx which forms a lid over the flowers when in bud. Viminalis is derived from the Latin viminis ’twig’, in reference to the suitability of this plants twigs for basket making.
