There is a collection of this species by Charles Sturt in the Natural History Museum, London - see Solanaceae Source
Derivation of epithet
The specific epithet is a reference to Kars Station in NSW where some of the early collections of the species were made.
The epithet was spelt "karsensis" in the protologue, but has since been corrected to "karsense".
