Pale Mexican Pricklypoppy (Argemone ochroleuca)

Description

Stems are bluish-green, pithy, smooth or slightly pubescent (covered with short hairs). The stems grow 30 to 100cm high, with scattered stiff yellow prickles. The seed leaves are stalkless, narrow lance shaped, curved and whitish-turquoise with white veins and are about 26mm long by 1.3mm wide at the first true leaf stage. The first true leaf is narrow with three triangular, pointed lobes at the tip and a tapering base. The second true leaf is also narrow but is deeply lobed. The leaves are bluish-green and alternate. The basal leaves are slightly stalked and crowded into a dense rosette (a cluster of leaves at the base of a plant often lying flat against the ground). The upper leaves are sessile (without a stalk) and clasping the stem, the shape being variable. The leaves are generally 6 to 20cm long, 3 to 8cm wide, deeply divided into 7 to 11 coarse irregular lobes, covered with a powdery bloom, the upper surface of the leaf has paler stripes along the veins. The margin (edge) of the leaf has wavy prickles at the tips of the lobes as well as scattered on the underside of the leaf.
