General Appearance

Carduus argentatus L. / Syn. Carduus argentatus var. argentatus, it is an annual herb, slender, arachnoid-hairy. up to 20-40 (-100) cm tall, simple or branched. Stems continuously winged below; wings c. 5 mm broad, sinuately lobed; lobes rounded or broadly triangular, spinulose on margins, with apical spines up to 2 mm. Leaves glabrous or sparsely hairy above, greyish or ash-coloured arachnoid hairy beneath, with straight unicellular and few multicellular hairs on veins, pinnatifid with lateral lobes 3-6 paired; lobes triangular, broadly lobulate, shortly spinulose tipped and margined. Basal leaves oblanceolate, attenuate below in a short, winged petiole. Cauline leaves oblong lanceolate, sessile. amplexicaule and decurrent. Capitula 15-18 x 10-13 mm, oblong, central axis with a single capitulum on 5-12 cm long, naked, whitish or greyish tomentose peduncles; lateral branches with 1-2 (-3) terminal capitula on 0.5·5 cm long peduncles; peduncle c. 1 mm in diam. occasionally with 1-2 reduced, lanceolate, leaf-like bracts. Involucre 14-17 x 10-13 mm. broadly oblong, glabrous or sub floccose. Involucral bracts closely imbricate or slightly squarrose, regularly enlarging inwards. Involucral bracts of 1st and 2nd rows 4-6 x 0.75-1 mm, ovate, proximal two third velnless, ± venuculose, distal one third keeled at the back, greenish, acuminate-spinose; margins scarious. Involucral bracts of 3rd and 4th rows 6-9 x 1-1.5 mm, similar in outline, texture and nervalion to the outer involucral bracts, but slightly constricted at c. two third from the base. Inner most involucral bracts up to 13 x3 mm, ± lanceolate in outline, with scarious margins and tips, inconspicuously 3-veined in the upper half. Corolla 9-12 mm, purplish pink; basal tube widened above into an ellipsoid, dark coloured cup of c. 1.5 mm diam; lobese, 6 mm long, all lobes equal.  Cypscla 34 (-5) x2 mm (+ umbo 0.5 mm); umbo cylindrical, 5-angledat the apex; pappus 10-12 mm.
