Chenopodium perttii Sukhor.

Annual up to 1(1.5–2) m with erect, scarcely branched stem. Leaves dark green, petiolate (petioles up to 3 cm), blades 3–4 × 2–3 cm, base truncate or broadly cuneate, margins often red; lower leaves triangular, entire to lobate; middle leaves trilobate with elongated mid-lobe (less than two times as long as the lateral ones) gradually tapering to apex and slightly upward-directed lateral lobes, lobes mostly entire; upper leaves also trilobate or entire, narrowly oblong. Inflorescence green, aphyllous or rather bracteose. Fruit ~1.5 mm, pericarp separating from the seed (not easily) with minute papillae that are hardly restored after soaking, almost smooth in dry fruit. Seed prominently keeled, surface with radial striae (Fig. 10E, F).
