Sarcochilus hartmannii is a lithophytic (sometimes an epiphyte or terrestrial) herb with stems 200–800 mm (7.9–31 in) long and which forms spreading clumps, usually on rocks.

[1][3][4][5] Sarcochilus hartmannii was first formally described in 1874 by Ferdinand von Mueller and the description was published in Fragmenta phytographiae Australiae from a specimen collected near Toowoomba by Carl Heinrich Hartmann.

It is found between Gympie in south-east Queensland and the Richmond River in New South Wales.
