Editing Eucalyptus regnans (section)

== Description ==
''Eucalyptus regnans'' is a broad-leaved, [[evergreen]] tree that typically grows to a height of {{cvt|70-114|m}} but does not form a [[lignotuber]]. The [[Crown (botany)|crown]] is open and small in relation to the size of the rest of the tree. The trunk is straight with smooth, cream-coloured, greyish or brown bark with a stocking of more or less fibrous or flaky bark that extends up to {{cvt|5-20|m}} at the base. The trunk typically reaches a diameter of {{cvt|2.5|m}} at breast height ([[Diameter at breast height|DBH]]). Young plants and [[coppice]] regrowth have glossy green, egg-shaped leaves that are held horizontally, {{cvt|55-120|mm}} long and {{cvt|22-50|mm}} wide and [[Petiole (botany)|petiolate]]. Adult leaves are arranged alternately along the stems, the same shade of glossy green on both sides, lance-shaped to broadly lance-shaped or sickle-shaped, {{cvt|90-230|mm}} long and {{cvt|15-50|mm}} wide, tapering to a reddish petiole {{cvt|8-25|mm}} long. The upper and lower surfaces of the leaves are dotted with numerous tiny, circular or irregularly-shaped oil glands. Secondary leaf veins arise at an acute angle from the midvein and tertiary venation is sparse.<ref name="CANBR" /><ref name="Costermans1981">{{cite book|author=Costermans, Leon| title=Native Trees and Shrubs of South-eastern Australia|publisher=Rigby|location= Kent Town, South Australia | year=1981 |page=338| isbn =978-0-7270-1403-0}}</ref><ref name="Nicolle2006">{{cite book|author=Nicolle, Dean|title=Eucalypts of Victoria and Tasmania|url=https://books.google.com/books?id=QpFROgAACAAJ|year=2006|publisher=Bloomings Books|location=Melbourne, Victoria| pages=244–45|isbn=978-1-876473-60-0}}</ref><ref name="ABRS">{{cite web |last1=Chippendale |first1=George M. |title=''Eucalyptus regnans'' |url=https://profiles.ala.org.au/opus/foa/profile/Eucalyptus%20regnans |publisher=Australian Biological Resources Study, Department of the Environment and Energy, Canberra |access-date=11 December 2019}}</ref><ref name=Brooker>{{cite book|last=Brooker|first=Ian|author2=Nicolle, Dean|title=Atlas of Leaf Venation and Oil Gland Patterns in the Eucalypts|publisher=Csiro Publishing|location=Collingwood, VIctoria|date=2013|pages=195|isbn=9780643109865|url=https://books.google.com/books?id=Eq69sliNmRIC&pg=PA195 }}</ref>  
 
The flower buds are arranged in leaf [[wikt:axil|axil]]s in groups of between nine and fifteen on one or two unbranched [[Peduncle (botany)|peduncles]] {{cvt|4-14|mm}} long, the individual buds on [[Pedicel (botany)|pedicels]] {{cvt|3-7|mm}} long. Mature buds are oval, {{cvt|4-7|mm}} long and {{cvt|2-4|mm}} wide with a rounded [[Operculum (botany)|operculum]]. Flowering occurs from March to May and the flowers are white. The fruit is a woody, cup-shaped or conical [[Capsule (botany)|capsule]] {{cvt|5-8|mm}} long and {{cvt|4-7|mm}} wide on a pedicel {{cvt|1-7|mm}} long and usually with three valves near the level of the rim. The seeds are pyramid-shaped, {{cvt|1.5-3|mm}} long with the [[Hilum (biology)|hilum]] at the end.<ref name="CANBR"/><ref name="Costermans1981" /><ref name="ABRS"/><ref name="Brooker"/>

Seedlings have kidney shaped [[cotyledon]]s, and the first two to three pairs of leaves are arranged in opposite pairs along the stem, then alternate.<ref name="CANBR"/><ref name="Boland"/>
