With affinities to Pultenaea blakelyi, differing in larger, more rigidly pungent leaves, longer stipules (2.8–3.2 vs 0.8–1.5 mm), larger calyx (5.8–6.8 vs 4–5.2 mm long) and larger standard (8.5–9.2 vs 5.4–7.6 mm long). Similar to Pultenaea flexilis, but with longer leaves with distinctive conical papillae below.
