Affinity:— Differs from subsp. sarissa mainly in the bracts, which are not imbricate or concealing the inflorescence, are not prominently striate and are longer than in subsp. sarissa ( subsp. sarissa 0.5–1.5 mm long). The flowers of subsp. sarissa are generally smaller (e.g. calyx ca. 2.5 mm long, standard ca. 5.5–6 mm broad).
