Eucalyptus siderophloia, commonly known as the northern grey ironbark,{{cite web |last1=Chippendale |first1=George M. |title=Eucalyptus siderophloia |url=https://profiles.ala.org.au/opus/foa/profile/Eucalyptus%20siderophloia |publisher=Australian Biological Resources Study, Department of the Environment and Energy, Canberra |access-date=22 December 2019}} is a medium-sized to tall ironbark tree that is endemic to south eastern Australia. It has hard, dark, furrowed bark, lance-shaped to curved adult leaves, flower buds in groups of seven, white flowers and cup-shaped or conical fruit.
Description
Eucalyptus siderophloia is a tree that typically grows to a height of {{cvt|20-45|m}} and forms a lignotuber. It has hard, rough, furrowed grey or black bark on the trunk and branches, sometimes smooth on the thinner branches. Young plants and coppice regrowth have egg-shaped to lance-shaped leaves that are paler on the lower surface, {{cvt|50-120|mm}} long and {{cvt|15-48|mm}} wide. Adult leaves are the same shade of green on both sides, lance-shaped to curved, {{cvt|85-175|mm}} long and {{cvt|15-30|mm}} wide, tapering to a petiole {{cvt|10-25|mm}} long. The flowers are mostly arranged on the ends of branchlets in groups of seven on a branched peduncle {{cvt|5-12|mm}} long, the individual buds on pedicels {{cvt|2-8|mm}} long. Mature buds are diamond-shaped or spindle-shaped, {{cvt|5-10|mm}} long and {{cvt|3-4|mm}} wide with a conical operculum. Flowering mainly occurs from September to January and the flowers are white. The fruit is a woody cup-shaped or conical capsule {{cvt|3-8|mm}} long and {{cvt|4-7|mm}} wide with the valves near rim level.{{cite web |title=Eucalyptus siderophloia |url=https://apps.lucidcentral.org/euclid/text/entities/eucalyptus_siderophloia.htm |publisher=Euclid: Centre for Australian National Biodiversity Research |access-date=29 May 2020}}{{cite web |last1=Hill |first1=Ken |title=Eucalyptus siderophloia |url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Eucalyptus~siderophloia |publisher=Royal Botanic Garden Sydney |access-date=22 December 2019}}{{cite book |last1=Brooker |first1=Ian |last2=Kleinig |first2=David |title=Field Guide to Eucalypts (Volume 1) |date=1990 |publisher=Inkata Press |location=Melbourne |isbn=0909605629 |page=255}}
Taxonomy and naming
Eucalyptus siderophloia was first formally described in 1867 by George Bentham in Flora Australiensis.{{cite web|title=Eucalyptus siderophloia|url= https://id.biodiversity.org.au/instance/apni/455133|publisher=APNI|access-date=22 December 2019}}{{cite book |last1=Bentham |first1=George |last2=von Mueller |first2=Ferdinand |title=Flora Australiensis |date=1867 |publisher=Lovell Reeve and Co. |location=London |page=220 |url=https://www.biodiversitylibrary.org/page/11160778#page/228/mode/1up |access-date=22 December 2019}} Terri-barri is an Aboriginal word from the Sydney region. The specific epithet (siderophloia) is derived from Greek words meaning "iron" and "bark".{{cite book |last1=Robinson |first1=Les |title=Field guide to the native plants of Sydney |date=1991 |publisher=Kangaroo Press |location=Kenthurst |isbn=0864171927 |page=49}}
Distribution and habitat
This ironbark grows in forests on the coast and adjacent foothills in soils of reasonable fertility, from about Maryborough and Springsure in Queensland to near Sydney in New South Wales.
Uses
The sapwood is usually resistant to the lyctus borer. Not an easy timber to work, however it has a beautiful appearance similar to some rainforest species. Uses include flooring and decking, shipbuilding, poles, construction, railway sleepers and heavy engineering.
