Prasophyllum pictum is a member of the P. patens-P. odoratum species flock, and critical comparison with other members of this flock, including P. candidum, P. caricetum and P. sandrae by population genetic data is required. Described as allied to P. dossenum, but differing by its taller stature, more colourful flowers (with brown, pink or purple tones) and narrower oblong-lanceolate (vs ovate to ovate-oblong) labellum (3.5-4 vs 5-6 mm wide).
