Thick flat fleshy apple-green leaves retain broad shape year-round without severe winter reduction. Trap Architecture & Diagnostic Features: Homophyllous to semi-dimorphic adhesive flypaper trap. Unlike Mexican species that contract into tight, compact succulent resting buds in winter, P. agnata famously retains broad, thick, fleshy, pale apple-green leaves year-round. Leaves are oblong-spathulate with rounded, flat margins (lacking the strongly curled involute edges of P. ehlersiae). The upper surface is densely covered in stalked mucilage glands that glisten in morning light, accompanied by embedded sessile digestive glands that release proteases and phosphatases. Produces solitary white-to-pale-blue blossoms with soft lime-green throats on erect scapes.
