WorldFloraDB - Calyptocarpus vialis

Characteristics

Herbs, perennial. Stems prostrate, branched, rooting at nodes, densely appressed strigillose. Petiole 3-8 mm, narrowly winged toward blade, margin ciliate; leaf blade ovate to broadly ovate, to 35 × 25 mm, both surfaces densely appressed strigillose, base attenuate, margin crenate-serrate, apex acute, apiculate. Capitula axillary, solitary, subsessile; peduncle to 15 mm; involucre narrowly oblong-oblanceolate, 6-7 × 2.5-3.5 mm; phyllaries 4, 2-seriate, concave, lanceolate, 6-7 × 3-3.5 mm, apex acuminate and apiculate; paleae hyaline, narrowly elliptic, 3.5-4.8 × 0.8-1 mm. Ray florets 3-8, yellow; corolla 4.5-6.2 × 1.4-1.8 mm, 3-toothed; achenes oblanceolate, 3.5-4 × 1.7-2 mm; pappus of 2 ascending divergent awns, 1.2-2.4 mm. Disk florets 3-8; corolla 2.6-3.6 mm, apex 2-or 3-toothed or entire, densely papillose within; achenes similar to those of ray florets but slightly narrower and thicker, sometimes 3-angled, 1.1-1.7 mm wide, evidently muricate. 2n = 24.

More

Herbaceous annual or short-lived perennial; stems rounded, prostrate to 60 cm long, some-times rooting at nodes, with densely appressed hairs 0.2–0.6 mm long. Leaves ovate-triangular, 15–45 mm long, 8–40 mm wide, crenate-serrate, acute and apiculate, densely appressed-strigose on both surfaces, especially on abaxial surface; petiole 5–11 mm long, narrowly winged at apex. Capitula solitary at each node, 5–10 mm long; involucral bracts pilose; paleae white, linear-lanceolate, concavo-convex, entire or slightly laciniate, acute. Ray florets 3–7 (–8). Disc florets 3–7 (–8); corolla densely papillose within. Achenes obconical, slightly 3-or 4-angled, 3–4 mm long; ray achenes irregularly thickened on margins near apex; disc achenes ±smooth; awns erect and divergent, 1.5–2 mm long.

Leaf blades 1–3(–6) cm. Rays often inconspicuous, laminae mostly 2–5 mm. Cypselae 2–4 mm; pappi of ± erect to spreading awns, the longer 1–2(–3+) mm. 2n = 24.
