}} Podochilus australiensis, commonly known as the native stream orchid,[2] is a species of epiphytic or lithophytic orchid. It has a fern-like appearance with many thin, twisted, glossy green leaves and clusters of up to six dull white or greenish flowers with a green labellum. It grows tropical North Queensland. DescriptionPodochilus australiensis is an epiphytic or lithophytic herb with unbranched, slightly flattened stems {{convert|200-600|mm|in|sigfig=2}} long and about {{convert|3|mm|in|sigfig=2}} long wide. There are many thin, glossy, dark green leaves {{convert|30-45|mm|in|sigfig=2}} long and {{convert|10-15|mm|in|sigfig=2}} wide, giving the plant a fern-like appearance. Between two and six dull white or greenish cream-coloured flowers about {{convert|3.5|mm|in|sigfig=2}} long and wide are borne on short flower stems. The sepals and petals spread widely apart from each other, the dorsal sepal about {{convert|2.5|mm|in|sigfig=2}} long and {{convert|1.5|mm|in|sigfig=2}} wide, the lateral sepals slightly wider and the petals shorter and narrower. The labellum is green, about {{convert|2|mm|in|sigfig=2}} long and {{convert|1|mm|in|sigfig=2}} wide and has a deep spur at its base. Flowering occurs from March to June.[2][3]Taxonomy and namingThe native stream orchid was first formally described in 1886 by Frederick Manson Bailey who gave it the name Eria australiensis and published the description in Occasional Papers on the Queensland Flora.[1][4] In 1907 Rudolf Schlechter changed the name to Podochilus australiensis.[5] The specific epithet (australiensis) refers to Australia, the ending -ensis being a Latin suffix "denoting place", "locality" or "country".[6] Distribution and habitatPodochilus australiensis grows in humid forests, often on branches over streams or on rotting logs and boulders. It is found between the McIlwraith Range and the Tully River in Queensland.[2]Use in horticultureEasy to grow, but needs water all year round, high humidity, and warmth (not below 10 °C). Can be grown on a slab or in a small pot with a coarse mix.[2] References1. ^1 2 {{WCSP |161704 |Podochilus australiensis}} 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=461}} 3. ^{{cite web |title=Appendicula australiensis |url=http://keys.trin.org.au:8080/key-server/data/08090a09-0d0e-410b-860c-020705070e0e/media/Html/Appendicula_australiensis.htm |publisher=Trin keys: Australian Tropical Rainforest Orchids |accessdate=10 January 2019}} 4. ^{{cite web|title=Eria australiensis|url= https://id.biodiversity.org.au/instance/apni/587670|publisher=APNI|accessdate=10 January 2019}} 5. ^{{cite web|title=Podochilus australiensis|url= https://id.biodiversity.org.au/instance/apni/514260|publisher=APNI|accessdate=10 January 2019}} 6. ^{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.|page=303}} External links
