Eucalyptus sargentii

Eucalyptus sargentii is a tree or a mallee that typically grows to a height of {{cvt|3-12|m}} but does not usually form a lignotuber (a mallet). It has smooth greenish bark that is brownish when new, usually with rough, greyish flaky bark on part or all of the trunk. Adult leaves are arranged alternately, the same shade of green on both sides, linear to narrow lance-shaped or curved, {{cvt|53-126|mm}} long and {{cvt|5-13|mm}} wide tapering to a petiole {{cvt|5-18|mm}} long. The flower buds are arranged in leaf axils in groups of seven on an unbranched peduncle {{cvt|7-20|mm}} long, the individual buds on pedicels {{cvt|3-6|mm}} long. Mature buds are an elongated oval shape, {{cvt|16-26|mm}} long and {{cvt|4-5|mm}} wide with a horn-shaped operculum that is about twice as long as the floral cup. Flowering occurs from August or October to December or January and the flowers are whitish to creamy yellow. The fruit is a woody conical capsule {{cvt|6-9|mm}} long and {{cvt|5-8|mm}} wide with the valves near rim level.{{cite web |title=Eucalyptus sargentii subsp. sargentii |url=https://apps.lucidcentral.org/euclid/text/entities/eucalyptus_sargentii_subsp._sargentii.htm |publisher=Euclid: Centre for Australian National Biodiversity Research |access-date=29 May 2020}}{{cite web |last1=Chippendale |first1=George M. |title=Eucalyptus sargentii |url=https://profiles.ala.org.au/opus/foa/profile/Eucalyptus%20sargentii |publisher=Australian Biological Resources Study, Department of the Environment and Energy, Canberra |access-date=18 December 2019}}

Eucalyptus sargentii was first formally described in 1924 by Joseph Maiden in his book A Critical Revision of the Genus Eucalyptus.{{cite web|title=Eucalyptus sargentii|url= https://id.biodiversity.org.au/instance/apni/455106|publisher=APNI|access-date=18 December 2019}}{{cite book |last1=Maiden |first1=Joseph |title=A Critical Revision of the Genus Eucalyptus |date=1924 |publisher=New South Wales Government Printer |location=Sydney |pages=58–60 |url=https://www.biodiversitylibrary.org/item/123315#page/104/mode/1up |access-date=18 December 2019}} The specific epithet honours Oswald Hewlett Sargent, a pharmacist and naturalist from York.{{cite web |title=Sargent, Oswald H.

In 1992, Lawrie Johnson and Ken Hill described E. sargentii subsp. fallens and E. sargentii subsp. sargentii (the autonym,{{cite journal |last1=Johnson |first1=Lawrence A.S. |last2=Hill |first2=Kenneth D. |title=Systematic studies in the eucalypts. 5.

The name onesis'' is from an ancient Greek word meaning "advantage" or "use", referring to the potential use of this subspecies in reclaiming saline sites.{{cite book |author=Francis Aubie Sharr |author-link=Francis Aubie Sharr |title=Western Australian Plant Names and their Meanings |date=2019 |publisher=Four Gables Press |location=Kardinya, Western Australia |isbn=9780958034180 |page=372}}

Salt River gum grows in open woodland in low-lying, poorly drained areas near salt lakes and salt creeks. It has a scattered distribution from Pithara to Lake Grace in the Avon Wheatbelt biogeographic region. Subspecies onesis is restricted to seven populations between Piawaning, York and Cunderdin.

Subspecies sargenti is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife,{{FloraBase|name=Eucalyptus sargentii subsp. sargentii|id=13034}} but subspecies onesis is classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife meaning that it is poorly known and known from only a few locations but is not under imminent threat.{{cite web|title=Conservation codes for Western Australian Flora and Fauna|url=https://www.dpaw.wa.gov.au/images/documents/plants-animals/threatened-species/Listings/Conservation%20code%20definitions.pdf|publisher=Government of Western Australia Department of Parks and Wildlife|access-date=18 December 2019}}
