Prasophyllum graniticola is a member of the P. patens-P. odoratum species flock, and critical comparison with other members of this flock, including P. album, P. anticum, P. canobolense, P. brevisepalum and P. holzingeri by population genetic data is required. Described as allied to P. odorata, but differing by the acuminate to long-acuminate tips on the sepals and a much broader and more conspicuous, raised, yellow labellum callus (3.5-4 mm wide vs 1.5 mm wide) extending well beyond the bend in the labellum.
