Plants from the Little and Big Deserts are typically smaller plants (to 10 cm high) with fewer (1–3), slightly smaller, paler flowers. They have been described as a distinct species, Urochilus arbusculus D.L.Jones & C.J.French (Jones & French 2017), but no combination currently exists for these in Pterostylis. Both taxa are illustrated in VicFlora.
