}}Sarcochilus hartmannii, commonly known as the large boulder orchid, [2] ravine orchid, Hartmann's sarcochilus or cliff orchid,[5] is a lithophytic orchid endemic to eastern Australia. It forms spreading clumps with between four and ten thick, channelled leaves and up to twenty five white flowers with crimson spots near the centre. DescriptionSarcochilus hartmannii is a lithophytic (sometimes an epiphyte or terrestrial) herb with stems {{convert|200-800|mm|in|sigfig=2|abbr=on}} long and which forms spreading clumps, usually on rocks. It has between four and ten thick, channelled linear to oblong or triangular leaves {{convert|80-200|mm|in|sigfig=2|abbr=on}} long and {{convert|15-20|mm|in|sigfig=1|abbr=on}} wide. Between five and twenty five white flowers with crimson spots near the centre, {{convert|25-30|mm|in|sigfig=2|abbr=on}} long and wide are crowded on an arching flowering stem {{convert|100-250|mm|in|sigfig=2|abbr=on}} long. The sepal are {{convert|12-16|mm|in|sigfig=2|abbr=on}} long and {{convert|5-8|mm|in|sigfig=2|abbr=on}} wide, the petals {{convert|10-14|mm|in|sigfig=2|abbr=on}} long and {{convert|4-6|mm|in|sigfig=2|abbr=on}} wide. The labellum is {{convert|2-3|mm|in|sigfig=1|abbr=on}} long, thick and waxy with three lobes. The side lobes are erect, about {{convert|3|mm|in|sigfig=2|abbr=on}} high and wide and the middle lobe is short and fleshy. Flowering occurs between September and November.[3][2][4][5]Taxonomy and namingSarcochilus hartmannii was first formally described in 1874 by Ferdinand von Mueller and the description was published in Fragmenta phytographiae Australiae from a specimen collected near Toowoomba by Carl Heinrich Hartmann.[6] The specific epithet (hartmannii) honours the collector of the type specimen.[7][8]Distribution and habitatThe large boulder orchid usually grows on boulders and cliffs, rarely on trees or cycads. It is found between Gympie in south-east Queensland and the Richmond River in New South Wales.[2][5] ConservationThis orchid is classed as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and the New South Wales Government Biodiversity Conservation Act 2016. The main threats to the species are illegal collecting and weed invasion.[3][2][4] {{Commons|Sarcochilus fitzgeraldii|Sarcochilus fitzgeraldii}}{{Taxonbar|from=Q7423576}}References1. ^1 {{WCSP | 185005 | Sarcochilus hartmannii }} 2. ^1 2 3 {{cite book|last1=Jones|first1=David L.|title=A complete guide to native orchids of Australia including the island territories|date=2006|publisher=New Holland|location=Frenchs Forest, N.S.W.|isbn=1877069124|pages =449}} 3. ^1 2 {{cite web |title=Approved Conservation Advice for Sarcochilus hartmannii (Waxy Sarcochilus)|url=http://www.environment.gov.au/biodiversity/threatened/species/pubs/4124-conservation-advice.pdf |publisher=Australian Government Department of the Environment |accessdate=5 January 2019}} 4. ^1 2 {{cite web |title=Hartman's Sarcochilus - profile |url=https://www.environment.nsw.gov.au/threatenedSpeciesApp/profile.aspx?id=10745 |publisher=New South Wales Government Office of Environment and Heritage |accessdate=5 January 2019}} 5. ^1 {{cite web |last1=Weston |first1=Peter H. |title=Sarcochilus hartmannii |url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Sarcochilus~hartmannii|publisher=Royal Botanic Garden Sydney |accessdate=5 January 2019}} 6. ^{{cite web|title=Sarcochilus hartmannii|url= https://id.biodiversity.org.au/instance/apni/468926|publisher=APNI|accessdate=5 January 2019}} 7. ^{{cite book |last1=von Mueller |first1=Ferdinand |title=Fragmenta phytographiae Australiae |date=1874 |publisher=Victorian Government Printer |location=Melbourne |page=248 |url=https://www.biodiversitylibrary.org/item/7225#page/249/mode/1up |accessdate=5 January 2019}} 8. ^{{cite web |title=Hartmann, Carl Heinrich (1833–1887) |url=http://www.anbg.gov.au/biography/hartmann-carl-heinrich.html |publisher=Australian National Herbarium |accessdate=5 January 2019}} 5 : Sarcochilus|Endemic orchids of Australia|Orchids of New South Wales|Orchids of Queensland|Plants described in 1874 |
