|}}Eucalyptus synandra, commonly known as Jingymia mallee, is a mallee that is native to Western Australia.[1]

Description

The mallee typically grows to a height of {{convert|3.5|to|10|m|ft|0}} with a width of {{convert|3|to|7|m|ft|0}} and has smooth, shedding bark and an erect to weeping habit. Usually the tree will form multiple stems from a lignotuber at the base of the trunks it also has a light open canopy that allows some light through.[2] It blooms between August and March producing inflorescences with pink-cream flowers[1] and a distinctive red capsule.[4] The juvenile leaves are dull and grey-green in colour. They are quite narrow around {{convert|90|mm|in|0}} in length and with a width of {{convert|15|mm|in|2|abbr=on}}.[3] The tree has dull green linear leaves that are about {{convert|200|mm|in|0|abbr=on}} in length[4] and {{convert|16|mm|in|2|abbr=on}} wide.[3] The simple inflorescences are held in the leaf axils and contain to seven flowers. Stalked buds form with hemispherical floral tubes, with a conical to beaked shaped bright red cap. The lower half of the stamens merge into a single tube. The creamy coloured flowers tend to turn pink as they age. After flowering hemispherical stalked fruits form which have a thick rim, an ascending disc and up to five exserted valves that are {{convert|6|to|14|mm|in|2|abbr=on}} in length.[3]

Taxonomy

The species was first formally described by the botanist M.D.Crisp in 1982 as part of the work Eucalyptus synandra (Myrtaceae), a new species of mallee from Western Australia published in the journal Nuytsia.[5] The type specimen was collected in 1981 by Alexander Segger George about {{convert|5|km|mi|1}} south of Jingymia in the Shire of Koorda.[6]

The species name synandra is latin in origin meaning with fused male parts[7] which refers to the plants flowers where the stamens are joined for a portion of their length.[12]

Distribution

It is found as several small populations[12] on sandplains and rises in an area between Geraldton and Mount Marshall in the Mid West, Wheatbelt regions where it grows in sandy and gravelly lateritic soils.[1] The 27 separate populations of the species, containing about 1200 individual plants are scattered over a {{convert|300|km|mi|0}} length mostly between north of Morawa to around Koorda. They are mostly found on road verges but also on private land, conservation areas, pastoral leases and a timber reserve.[3]

Usually found among heath and scrub communities. Associated species include Eucalyptus leptopoda, E. erwartiana, E. loxophleba subsp. supralaevis, E. subangusta, E. brachycorys, Acacia coolgardiensis, A. acuaria and Hakea recurva.[3]

Cultivation

Although the tree is not commonly cultivated,[8] it is commercially available in seed form or as seedlings. The drought tolerant plant[4] grows in full sun and attracts bids such as honeyeaters to the garden.[9]
