Treatment appears in FNA Volume 9. Treatment on page 566. Mentioned on page 565.

Leaf-blades narrowly ovate, 3–4 cm, base ± narrowly cuneate, sinuses deep (max LII 15–20%). Inflorescence branches sparsely pubescent. Flowers 15–20 mm diam. Pomes 8–15 mm diam.

Discussion

Of conservation concern.

Variety cuneata could perhaps be considered a 20-stamen variant of Crataegus fluviatilis or a particularly narrowly leaved form of C. flabellata var. grayana.
