Eucalyptus wandoo
Eucalyptus wandoo, commonly known as wandoo, dooto, warrnt or wornt and sometimes as white gum, is a small to medium-sized tree that is endemic to the southwest of Western Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of nine to seventeen, white flowers and conical to cylindrical fruit. It is one of a number of similar Eucalyptus species known as wandoo. E.wandoo was first described in 1934 by the Australian botanist William Faris Blakely in his book A Key to the Eucalypts using material collected by the English collector Augustus Frederick Oldfield from a sand plain along the Kalgan River. , Plants of the World Online lists Eucalyptus redunca var. elata as a taxonomic synonym of E.wandoo. The range of the tree extends from Morawa in the north extending south through the Darling Range down to around the Stirling Range to the south coast near the Pallinup River. There is an outlying population found to the east of Narembeen at Twine Reserve. It is native to the following IBRA bioregions: Geraldton Sandplains and Avon Wheatbelt in the north through the Swan Coastal Plain and Jarrah Forest to the Esperance Plains and Mallee in the south. E.wandoo was listed as Vulnerable by the International Union for Conservation of Nature (IUCN) as a result of its severely fragmented population. Description Eucalyptus wandoo is a tree that typically grows to a height of and sometimes to , and has a DBH. The bole or trunk of the tree is usually straight and comprises 50–65% of the total height of the tree. E.wandoo can have a long lifetime, with some trees in excess of 150 years of age and others in excess of 400 years. As trees age the growth rate slows down making an accurate determination of age more difficult. It forms an inconspicuous lignotuber, the woody tuber that begins to develop near the base of seedlings, but can become huge in older trees and contains embedded epicormic buds that allow the plant to regenerate following destruction of the crown following fire or drought. Saplings, young trees and coppice regrowth have rough and fibrous yellow-brown bark on the stems that become smoother as trees mature. The stems of saplings can be circular or square shaped in cross section and have a powdery coating (glaucous). Older trees have smooth powdery or non-powdery white bark, often with patches of white, grey or light brown giving the trunk a mottled appearance. Old layers of darker coloured bark are scattered and loosely held and are shed in flakes; it is not uncommon for a few flakes to persist on the trunk for a long time. The bark is shed in irregular slabs. Branchlets do not have a powdery coating as the bark of older trees can. The soft central cylinder of tissue within, the pith, contains many glands. Young plants and coppice regrowth have blue-green leaves that are arranged oppositely (borne at the same level but on directly opposite sides of their common
