The new species had previously been included in E. nubilis Maiden & Blakely (syn. Eucalyptus nubila L.A.S.Johnson, orth. var.), but differs in the ribbed hypanthium, hemispherical to bluntly-conical calyptra which is shorter than the hypanthium, and the slightly larger, globular or occasionally obconical, ribbed fruit. At present, E. calidissima is known only from a single population occurring across c. 200 ha and is considered rare, but it is not under immediate threat.

Spatial analysis of all records (n=588) showed that the species is most prevalent on Permian-aged sediments but also occurs on older Carboniferous sediments and younger Triassic Narrabeen and Quaternary substrates. Point records intersect with a wide range of annual average rainfall bands (<700 to 1400 mm/yr), suggesting either that the species is tolerant of a variety of soil moisture gradients, or that current distribution may be representative of a differing climatic environment. Interpolation of database records (n=397) across 175,000 hectares of high-resolution vegetation mapping showed Macrozamia flexuosa to most frequently occur within the Lower Hunter Spotted Gum-Ironbark Forest (41%), followed by Kurri Sands Swamp Woodland (16%), Coastal Foothills Spotted Gum-Ironbark Forest (15%) and Coastal Plains Smooth-barked Apple Woodland (13%). Numerical analysis of full floristic plot data (n=86) largely supported these results, with the addition of Hunter Valley Moist Forest to these four regional communities. A revised assessment of the conservation significance of Macrozamia flexuosa suggests that the existing conservation risk code of 2K be amended to 3RCa (distributional range >100km; rare but not immediately threatened; adequately conserved in at least 14 conservation reserves). An extent of occurrence of 6,319 km² and an area of occupancy of 696 km² have been determined for the species, and an estimated population size of between 1,740,000 and 43,500,000 individuals has been calculated. Under IUCN threat criteria, a code of NT (Near Threatened) is here considered appropriate for Macrozamia flexuosa, recognising uncertainties applicable to the assessment of Criteria A and B. It is noted, however, that Macrozamia flexuosa may currently be in slow decline due to as yet unknown limitations in flowering, pollination and/or dispersal mechanisms over a long period of time (many decades), with the longevity of individual specimens confounding any observable trends. A lack of demographic data relevant to these life traits limits comprehensive assessment, and further research to address these data gaps is recommended.]]> Tue 20 Aug 2019 17:21:41 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:19881 100 times) across other parts of NSW, Queensland, and South Australia. Historical herbarium and database records show a paucity of records from the Hunter prior to the year 2000, after which a 37-fold increase in observations since 1951 is apparent. For the first 128 years of botanical exploration, 1823 to 1951, there are no validated collections or records of Acacia pendula from the Hunter Valley. The single exception is a specimen collected by Cunningham from 1825 (lodged at Kew, UK), purported to be from 'Hunters River', but which is morphologically different to other collections of Acacia pendula from that time. There is uncertainty over its origins as this collection (not specifically mentioned in Cunningham's journal) is mounted on the same sheet as a specimen from the Lachlan River. It does, however, appear similar in morphology to current day Hunter Valley specimens presently attributed (perhaps incorrectly) to Acacia pendula. Analysis of habitats supporting Acacia pendula in NSW outside of the Hunter show them to differ significantly in geological age, soil type, rainfall and elevation. Collectively, these findings provide a strong circumstantial case that Acacia pendula was absent from the Hunter at the time of European settlement; this has important implications for the conservation and management of Hunter stands. Rather than being a threatened species in the Hunter Valley, it is postulated that Acacia pendula has been intentionally and/or accidentally introduced to the region, and may now be imposing a new and emerging threat to the endangered grassy woodlands and forests there. There is now an urgent need for genetic studies to clarify the origins of the Hunter Valley stands, and to define the taxonomic limits of Acacia pendula and its close relatives. There is also the possibility that a new undescribed taxon may be present in the Hunter Valley population, which will require resolution. It seems more likely, however, that neotony (retention of juvenile features in the adult phase), apomixis (replacement of sexual reproduction by asexual reproduction), and/or vigorous root suckering may be operating on introduced Acacias growing in response to unfavourable habitat within the Hunter Valley.]]> Thu 25 Jun 2020 10:48:02 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:1788 Sat 24 Mar 2018 08:27:31 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:17091 Sat 24 Mar 2018 08:05:37 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28609 Sat 24 Mar 2018 07:38:56 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28940 Midlothian, led by the Minister Rev. William Mclntyre, arrived in Sydney from the Isle of Skye and they had been encouraged by Rev. Dr John Dunmore Lang to immigrate. The majority of these immigrants could only speak Gaelic. The immigrants eventually settled on Lang's brother's property in the Hunter Valley and became tenants, and not servants. The township in the Hunter Valley became known as Largs, named after the Lang family's home town in Ayrshire, Scotland. Gaelic was the initial language of the town and church services were originally conducted in Gaelic. The Sydney papers were outraged and the Sydney Monitor stated, 'We want them [the Highlanders] only as servants: and wanting them as servants we cannot want them as tenants.' However, the immigrants remained in Largs and built a small thriving community. This paper looks at the controversy and establishment of the Gaelic community at Largs.]]> Sat 24 Mar 2018 07:31:25 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3464 Sat 24 Mar 2018 07:20:31 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3355 Sat 24 Mar 2018 07:18:31 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:21919 Sat 24 Mar 2018 07:15:39 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55203 Mon 29 Apr 2024 11:18:49 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:6253 Mon 26 Nov 2018 09:58:14 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:8539 Mon 23 Sep 2019 11:55:24 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34891 Mon 23 Sep 2019 10:22:40 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37142 Fri 21 Aug 2020 10:57:43 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37307 Fri 19 Feb 2021 15:31:56 AEDT ]]>
