==Description==
''Eucalyptus goniocarpa'' is a mallet, often with a short trunk, that typically grows to a height of {{cvt|5|m}}, or sometimes a multi-stemmed [[Mallee (habit)|mallee]] to {{cvt|4|m}}, but does not form a [[lignotuber]]. It has smooth, grey to brown bark. Young plants and [[coppice]] regrowth have lance-shaped, [[Petiole (botany)|petiolate]] leaves that are {{cvt|45-87|mm}} long and {{cvt|13-25|mm}} wide. Adult leaves are lance-shaped, glossy bluish, {{cvt|45-95|mm}} long and {{cvt|5-12|mm}} wide on a petiole up to {{cvt|8|mm}} long. The flower buds are arranged in groups of three, sometimes seven, in leaf [[wikt:axil|axil]]s, on a flattened, unbranched [[Peduncle (botany)|peduncle]] {{cvt|12-30|mm}} long, the individual buds on [[Pedicel (botany)|pedicels]] {{cvt|5-10|mm}} long. Mature buds are elongated oval to spindle-shaped, {{cvt|11-17|mm}} long and {{cvt|5-7|mm}} wide with two wings along the sides and an [[Operculum (botany)|operculum]] up to twice as long as the [[Hypanthium|floral cup]]. The flowers are creamy white and the fruit is a woody conical to barrel-shaped [[Capsule (botany)|capsule]] {{cvt|12-14|mm}} long and {{cvt|9-12|mm}} wide with two wings that extend down the pedicel.<ref name=FloraBase>{{FloraBase|name=''Eucalyptus goniocarpa''|id=13028}}</ref><ref name="CANBR">{{cite web |title=''Eucalyptus goniocarpa'' |url=https://apps.lucidcentral.org/euclid/text/entities/eucalyptus_goniocarpa.htm |publisher=Euclid: Centre for Australian National Biodiversity Research |access-date=21 July 2019}}</ref><ref name="Telopea">{{cite journal |last1=Hill |first1=Kenneth D. |last2=Johnson |first2=Lawrence A.S. |title=Systematic studies in the eucalypts. 5.
