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. As of January 2023[update], 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 of 2019[update] as a result of its severely fragmented population.
Eucalyptus wandoo is a tree that typically grows to a height of 3 to 25 m (9.8 to 82.0 ft) and sometimes to 30–31 m (98–102 ft), and has an 80 to 100 cm (31 to 39 in) 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 axis) for two to four nodes where the leaves arise then arranged alternately (found singly at different levels along the stem). The leaves can be egg-shaped, broadly lance-shaped or D-shaped. The leaves can have a length of 45–150 mm (1.8–5.9 in) and a width of 25–75 mm (0.98–2.95 in). Adult leaves are the same shade of greyish-green or greyish-blue on both sides but can sometimes be a glossy green. The adult leaves are lance-shaped or have a curved lance shape. Adult leaves are 75–125 mm (3.0–4.9 in) in length and 10–28 mm (0.39–1.10 in) wide on a petiole 10–20 mm (0.39–0.79 in) long. The side veins in the leaves are at an angle greater than 45° to the midrib and there is moderate to dense reticulation; the leaf oil glands are found at the intersections of the veinlets.
The inflorescences are arranged in leaf axils in groups of nine to seventeen on an unbranched peduncle 8–20 mm (0.31–0.79 in) long, the individual buds on pedicels 3–5 mm (0.12–0.20 in) long. Mature buds are spindle-shaped but curved and with a scar present, the buds are 8–14 mm (0.31–0.55 in) in length and 2–4 mm (0.079–0.157 in) wide with a conical operculum up to twice as long as the floral cup. There are some erect outer stamens; the majority of stamen are bent sharply downward to some degree. The oblong anthers are attached dorsally to the filament and burst open spontaneously via longitudinal slits. It has a straight and long style and a blunt to rounded stigma leading to the ovary that has three to four cavities containing four vertically arranged rows of ovules. Flowering occurs between March and June for wandoo found to the north of the Avon Valley; these are known as the winter wandoo. The spring wandoo found to the south of Wandering flowers in spring and early summer or from September to January, while the summer wandoo, also found to the south of Wandering, flowers from January to February. The flowers are white or cream-coloured. The pollen and nectar are a valuable source of protein, vitamins, fats and minerals for honey bees. Analysis of amino acids in the pollen yield results of 1.69–1.91% aspartic acid, 2.23–2.54% glutamic acid, 2.52–2.67% proline and 1.63–1.69% arginine. The total amount of protein in the pollen was 21.8–23.7%.
