Between three and twelve cream-coloured flowers with large purple or reddish blotches, {{convert|12-16|mm|in|sigfig=2|abbr=on}} long and {{convert|12-15|mm|in|sigfig=2|abbr=on}} wide are arranged on a pendulous stem {{convert|50-70|mm|in|sigfig=1|abbr=on}} long. The sepals and petals are elliptic to spatula-shaped and the flowers are sometimes cup-shaped. The dorsal sepal is {{convert|7-10|mm|in|sigfig=2|abbr=on}} long and {{convert|3-4|mm|in|sigfig=2|abbr=on}} wide whilst the lateral sepals are slightly longer and wider. The petals are {{convert|6-9|mm|in|sigfig=2|abbr=on}} long and about {{convert|3-4|mm|in|sigfig=2|abbr=on}} wide. The labellum is cream-coloured with purplish markings, about {{convert|1.5|mm|in|sigfig=1|abbr=on}} long with three lobes. The side lobes are erect, about {{convert|4|mm|in|sigfig=1|abbr=on}} long and curved inwards and the middle lobe has a rounded, fleshy spur about {{convert|2|mm|in|sigfig=1|abbr=on}} long. Flowering occurs between August and October.[3][2][4][5]Taxonomy and namingSarcochilus weinthalii was first formally described in 1904 by Frederick Manson Bailey and the description was published in the Queensland Agricultural Journal from a specimen collected near Toowoomba by "F. Weinthal".[6] The specific epithet (weinthalii) honours the collector of the type specimen.[6]Distribution and habitatThe blotched butterfly orchid grows in forest and scrub in hilly between the Bunya Mountains in Queensland and the Richmond River in New South Wales.[2][4] 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 inappropriate fire regimes.[3][2][5] References1. ^1 {{WCSP | 185151 | Sarcochilus weinthalii }} {{Taxonbar|from=Q15495704}}{{DEFAULTSORT:Sarcochilus weinthalii}}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|page =452}} 3. ^1 2 {{cite web |title=Approved Conservation Advice for Sarcochilus weinthalii (blotched sarcochilus) |url=http://www.environment.gov.au/biodiversity/threatened/species/pubs/12673-conservation-advice.pdf |publisher=Australian Government Department of the Environment |accessdate=6 January 2019}} 4. ^1 {{cite web |last1=Weston |first1=Peter H. |title=Sarcochilus weinthalii |url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Sarcochilus~weinthalii |publisher=Royal Botanic Garden Sydney |accessdate=6 January 2019}} 5. ^1 {{cite web |title=Blotched Sarcochilus - profile |url=https://www.environment.nsw.gov.au/threatenedspeciesapp/profile.aspx?id=10746 |publisher=New South Wales Government Office of the Environment and Heriatage |accessdate=6 January 2019}} 6. ^1 {{cite web|title=Sarcochilus weinthalii|url= https://id.biodiversity.org.au/instance/apni/469700|publisher=APNI|accessdate=6 January 2019}} 4 : Endemic orchids of Australia|Orchids of New South Wales|Orchids of Queensland|Plants described in 1904 |
