Originally collected from near the mouth of the Murray River, the species was originally described as Sisymbrium cardaminoides by Ferdinand von Mueller in 1855,[3] before the genus Pachymitus was erected by Otto Eugen Schulz in 1924.
Pachymitus cardaminoides is a small herbaceous shrub which grows to 30 cm (12 in) in height. It is found in inland New South Wales, Victoria, and South Australia.
