Description
Eucalyptus pyrocarpa is a tree that typically grows to a height of {{cvt|30|m}} but does not form a lignotuber. It has rough, short fibrous to stringy, greyish brown bark on the trunk and larger branches, smooth white to grey bark above that is often shed in ribbons. Young plants and coppice regrowth have stems that are more or less square in cross-section, glaucous, sessile and arranged in opposite pairs. The juvenile leaves are lance-shaped, a lighter shade of green on the lower side, {{cvt|125-230|mm}} long and {{cvt|16-25|mm}} wide. Adult leaves are the same shade of green on both sides, lance-shaped to curved, {{cvt|90-240|mm}} long and {{cvt|15-40|mm}} wide on a petiole {{cvt|10-24|mm}} long. The flower buds are arranged in leaf axils in groups of seven, nine or eleven on a flattened, unbranched peduncle {{cvt|10-25|mm}} long, the individual buds on pedicels {{cvt|2-7|mm}} long. Mature buds are oval to spindle-shaped or diamond-shaped, {{cvt|9-13|mm}} long and {{cvt|6-7|mm}} wide with a conical to beaked operculum. Flowering has been recorded in March, February and August and the flowers are white. The fruit is a woody cup-shaped, barrel-shaped or pear-shaped capsule {{cvt|10-15|mm}} long and {{cvt|9-17|mm}} wide with the valves near rim level or enclosed below it.{{cite web |last1=Hill |first1=Ken |title=Eucalyptus pyrocarpa |url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Eucalyptus~pyrocarpa |publisher=Royal Botanic Garden Sydney |access-date=29 July 2019}}{{cite web |last1=Chippendale |first1=George M. |title=Eucalyptus pyrocarpa |url=https://profiles.ala.org.au/opus/foa/profile/Eucalyptus%20pyrocarpa |publisher=Flora of Australia.

Taxonomy and naming
In 1913, Joseph Maiden described Eucalyptus pilularis var. pyriformis from a specimen collected from Bucca Creek, near Coffs Harbour. The description was published in Journal and Proceedings of the Royal Society of New South Wales.{{cite web|title=Eucalyptus pilularis var. pyriformis|url= https://id.biodiversity.org.au/instance/apni/455825 |publisher=APNI|access-date=29 July 2019}}{{cite journal |last1=Maiden |first1=Joseph |title=Notes on Eucalyptus (with descriptions of new species) |journal=Journal and Proceedings of the Royal Society of New South Wales |date=1913 |volume=47 |issue=1 |pages=94–95 |url=https://www.biodiversitylibrary.org/item/130132#page/124/mode/1up |access-date=29 July 2019}} In 1973, Lawrie Johnson and Donald Blaxell raised the variety to species status but the name Eucalyptus pyriformis was already used for a Western Australian species. Johnson and Blaxell gave it the name E. pyrocarpa.{{cite web|title=Eucalyptus pyrocarpa|url= https://id.biodiversity.org.au/instance/apni/4 |publisher=APNI|access-date=29 July 2019}}
Distribution and habitat
Large-fruited blackbutt grows in forest on sloping country in coastal and sub-coastal ranges between the Washpool National Park, Wauchope and Woodburn.
