7. V. discoidea (L.) Loisel. , Not. Pl. Fr. 148 (1810).

Up to 30 cm. Lower cauline leaves narrowly spathulate to ovate, obtuse, entire to sinuate-dentate; middle cauline spathulate-lanceolate, coarsely toothed; upper linear-lanceolate, pinnatisect at base. Bracts ovate, scarious, ciliate. Fruits c. 2 mm, all in dense, globose, terminal clusters which fall as a whole, obconical to obpyramidal, obtusely 4-angled, densely villous; sterile loculi about as large as the fertile, not extending to base of fruit, separated by an oblong groove. Calyx somewhat longer than fruit, coroniform, reticulately veined, glabrous outside, usually densely hairy inside, divided to about the middle or almost to the base into 8-15 unequal, ovate-triangular teeth, each with an uncinate arista at the apex; rarely calyx with 6 subequal teeth. 2n = 14.

Variable especially in the number of calyx-teeth and in the hairiness of the inside of the calyx at the base. Plants from N.E. Spain (Ebro valley) with the calyx glabrous inside at the base, divided to the base into 12-16 narrowly ovate to triangularacuminate teeth have been called V. multidentata Loscos & Pardo , Ser. Pl. Arag. 49 (1863) (K coronata subsp. multidentata (Loscos & Pardo) Nyman ); their status is obscure.

V. platiloba Dufresne , Hist. Nat. Méd. Fam. Valér. 59 (1811), based on a single collection probably from Portugal, is like 7 but has only 6 transversely ovate, acuminate calyx-teeth, each with a more or less uncinate mucro; further information is required.
