(Some Australian state herbaria continue to use the name Callistemon shiressii.)[1] It is rare shrub or small tree with pale, papery bark, sharp-pointed leaves and spikes of white to pale cream bottlebrush flowers in spring and summer. DescriptionMelaleuca shiressii is a shrub or small tree growing to {{convert|12|m|ft|sigfig=1|abbr=on}} high with white or grey papery bark. Its leaves are arranged alternately and are {{convert|19-66|mm|in|sigfig=1|abbr=on}} long, {{convert|3-10|mm|in|sigfig=1|abbr=on}} wide, more or less flat, narrow elliptic or narrow egg-shaped and end in a sharp point. There is a mid-vein, marginal veins and 12-23 distinct lateral veins and there are many distinct oil glands. The edges of the leaves are often curled under and the lower surface is paler than the upper one.[2][3]The flowers are cream or greenish-cream and are arranged in spikes at the end of, or around the branches which continue to grow after flowering. The spikes are {{convert|18-22|mm|in|sigfig=1|abbr=on}} in diameter and {{convert|30-50|mm|in|sigfig=1|abbr=on}} long with 5 to 25 individual flowers. The petals are {{convert|1.7-3.3|mm|in|sigfig=1|abbr=on}} long and fall off as the flower ages and there are 48-84 stamens in each flower. Flowering occurs from September to January and is followed by fruit which are woody capsules, {{convert|2.5-3.7|mm|in|sigfig=2|abbr=on}} long and {{convert|5|mm|in|sigfig=1|abbr=on}} in diameter.[2][3] Taxonomy and namingMelaleuca shiressii was first named in 2006 by Lyndley Craven in Novon when Callistemon shiressii was transferred to the present genus.[4][5] Callistemon shiressii was first formally described in 1941 by William Blakely.[6] The specific epithet (shiressii) honours David William Campbell Shiress who, with William Blakely, collected the type specimen "on shale ridges about 1 mile north-west of Narara railway station".[2] David Shiress, who lived from about 1862 to 1944, was an accountant and apparently a friend of William Blakely.[7]Callistemon shiressii is regarded as a synonym of Melaleuca shiressii by the Royal Botanic Gardens, Kew.[8]Distribution and habitatMelaleuca shiressii occurs in and between the Singleton and Richmond districts in New South Wales. It grows in moist forests and on ridges .[2][3]GalleryReferences1. ^{{cite journal|last1=Udovicic|first1=Frank|last2=Spencer|first2=Roger|title=New combinations in Callistemon (Myrtaceae)|journal=Muelleria|date=2012|volume=30|issue=1|pages=23–25|url=http://www.rbg.vic.gov.au/documents/Muelleria_30-1_3_Udovicic_Spencer.pdf|accessdate=16 July 2015}} {{Taxonbar|from=Q20721728}}2. ^1 2 3 {{cite book|last1=Brophy|first1=Joseph J.|last2=Craven|first2=Lyndley A.|last3=Doran|first3=John C.|title=Melaleucas : their botany, essential oils and uses|date=2013|publisher=Australian Centre for International Agricultural Research|location=Canberra|isbn=9781922137517|page=325}} 3. ^1 2 {{cite web|last1=Spencer|first1=Roger|last2=Lumley|first2=Peter|title=Callistemon shiressii|url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Callistemon~shiressii|publisher=Royal Botanic Gardens Sydney: Plantnet|accessdate=17 July 2015}} 4. ^1 {{cite web|title=Melaleuca shiressii|url= https://biodiversity.org.au/boa/instance/apni/613706|publisher=APNI|accessdate=17 July 2015}} 5. ^{{cite journal|last1=Craven|first1=Lyn A.|title=New Combinations in Melaleuca for Australian Species of Callistemon (Myrtaceae)|journal=Novon|date=2006|volume=16|issue=4|page=473|doi=10.3417/1055-3177(2006)16[468:NCIMFA]2.0.CO;2|url=http://www.bioone.org/doi/10.3417/1055-3177%282006%2916%5B468%3ANCIMFA%5D2.0.CO%3B2|format=Submitted manuscript}} 6. ^{{cite web|title=Callistemon shiressii|url= https://biodiversity.org.au/boa/instance/apni/523051|publisher=APNI|accessdate=3 September 2015}} 7. ^{{cite web|title=Shiress, David William Campbell (c. 1862 - 1944)|url=http://www.anbg.gov.au/biography/shiress-david-william-campbell.html|publisher=Australian National Botanic Garden|accessdate=9 September 2015}} 8. ^{{WCSP | 31504 | Callistemon shiressii }} 3 : Melaleuca|Flora of New South Wales|Plants described in 1941 |
