Notes

A rare hybrid between Hinged Dragon Orchid (Caladenia drakeoides) and Salt Lake Spider Orchid (C. exilis). The species was named Caladenia × ornata by Stephen Hopper and Andrew Brown in 2001. However, as an Eastern Australian species had been named Caladenia ornata the previous year, the name of the Western Australian species was considered invalid and it was renamed C. × hopperi by Julian Shaw in 2014 in honour of WA Native Orchid Study and Conservation Group member: Steve Hopper
