Description
Dendrobium nindii is an epiphytic or lithophytic herb with cylindrical, dark blackish brown pseudobulbs {{convert|0.5-2.5|m|ft|sigfig=1|abbr=on}} long, {{convert|30-40|mm|in|sigfig=1|abbr=on}} wide and leafy in the upper half. There are between six and twenty two dark green and leathery leaves, {{convert|80-150|mm|in|sigfig=1|abbr=on}} long and {{convert|60-80|mm|in|sigfig=2|abbr=on}} wide arranged in two rows along the pseudobulbs. The flowering stem is at the tip of the pseudobulb, {{convert|200-500|mm|in|sigfig=1|abbr=on}} long and bears between eight and twenty mauve or violet flowers {{convert|50-60|mm|in|sigfig=2|abbr=on}} long and wide. The sepals and petals are slightly twisted and spread widely apart from each other. The lateral sepals are {{convert|30-40|mm|in|sigfig=2|abbr=on}} long and {{convert|14-18|mm|in|sigfig=2|abbr=on}} wide, the dorsal sepal slightly shorter. The petals are {{convert|35-50|mm|in|sigfig=2|abbr=on}} long and {{convert|4-5|mm|in|sigfig=2|abbr=on}} wide. The labellum is mauve or violet with darker veins, about {{convert|40|mm|in|sigfig=1|abbr=on}} long and wide with three lobes.

Taxonomy and naming
Dendrobium nindii was first formally described in 1874 by Walter Hill in Report on the Brisbane Botanic Garden from a specimen collected by Philip Henry Nind "on trees overhanging tidal streams, Moresby and Johnstone Rivers".{{cite web|title=Dendrobium nindii|url= https://id.biodiversity.org.au/instance/apni/505281|publisher=APNI|accessdate=28 November 2018}}{{cite book |last1=Hill |first1=Walter |title=Report on the Brisbane Botanic Garden |date=1874 |location=Brisbane |page=7 |url=http://bishop.slq.qld.gov.au/view/action/singleViewer.do?dvs=1543445600630~855&locale=en_AU&metadata_object_ratio=14&show_metadata=true&VIEWER_URL=/view/action/singleViewer.do?&DELIVERY_RULE_ID=10&frameId=1&usePid1=true&usePid2=true |accessdate=28 November 2018}} The specific epithet (nindii) honours the collector of the type specimen.
Distribution and habitat
The blue antler orchid grows in trees including mangroves and palms, in coastal swamps and near-coastal rainforest between the McIlwraith Range and Innisfail on the Cape York Peninsula. It also grows in similar habitats in New Guinea including on the Vogelkop Peninsula and Eilanden River.
Conservation
This orchid is classed as "endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and under the Queensland Government Nature Conservation Act 1992. The main threats to the species are land clearing and illegal collection.
