Description
Diuris jonesii is a tuberous, perennial herb, usually growing to a height of {{convert|250-400|mm|in|sigfig=1|abbr=on}}. Two or three leaves emerge at the base, each leaf {{convert|100-300|mm|in|sigfig=1|abbr=on}} long and {{convert|5-12|mm|in|sigfig=1|abbr=on}} wide. There are between two and eight yellow, mauve and brown flowers {{convert|40-50|mm|in|sigfig=2|abbr=on}} long and {{convert|20-35|mm|in|sigfig=1|abbr=on}} wide. The dorsal sepal is erect and the lateral sepals are narrow and hang downwards or sometimes cross each other. The petals are elongated and the labellum has spreading lateral lobes and a broad, flattened or folded centre lobe. The species is similar to the giant donkey orchid, D. amplissima but has smaller, less colourful flowers and a more coastal distribution. Flowering occurs from late September to October.{{cite book|last1=Brown|first1=Andrew|last2=Dixon|first2=Kingsley|last3=French|first3=Christopher|last4=Brockman|first4=Garry|title=Field guide to the orchids of Western Australia : the definitive guide to the native orchids of Western Australia|date=2013|publisher=Simon Nevill Publications|isbn=9780980348149|page=211}}{{cite book|last1=Hoffman|first1=Noel|last2=Brown|first2=Andrew|title=Orchids of South-West Australia.|date=2011|publisher=Noel Hoffman|location=Gooseberry Hill|isbn=9780646562322|page=474|edition=3rd}}
