5-5 cm in diameter (including floral bracts), floral bracts narrowly ovate, apex acuminate, distinctly canaliculate, navicular, ecarinate, strongly recurved, exceeding the sepals, yellowish-green to orange (when fully exposed), thin in texture, inconspicuously and sparsely white-lepidote near the base to glabrous, glabrous toward the apex, nerved abaxially, 25-35 x 11-15 mm, densely spinose, spines narrowly triangular, the basal ones retrorse the median to apical ones antrorse, uncinate, greenish except for the pale castaneous apex, 0.
minutum the general slimmer appearance, the narrower leaf blades which are canaliculate and distinctly narrowed toward the base, and the usually bipinnate and apically substellate inflorescence.

5 cm (not including the primary bracts), fascicles densely arranged, rachis not visible; primary bracts strongly spreading-recurved, longer than the fascicles, with a greenish, suborbicular base and a bronze-colored, narrowly triangular-attenuate, canaliculate, acuminate-caudate blade, densely and coarsely cinereous-lepidote on both sides, distinctly nerved abaxially, the basal ones 3 to 4 times longer than the fascicles (excluding the petals), the upper ones twice as long as the fascicles (excluding the petals), margins densely (at the base) to laxly (toward the apex) spinose, spines prevailingly spreadingretrorse, narrowly triangular-acicular, 1.
