Dizin: Jurinea

Jurinea, Alexandre Henri Gabriel de Cassini, 1821.
Geyikgöbeği.
Tribus Cardueae: Generally robust and often spiny herbs. Leaves alternate, usually divided or lobed, seldom entire. Capitula mostly homogamous and discoid with the corolla lobes often long and sometimes unequal, or heterogamous and disciform with marginal flowers female or neuter, often radiant, rarely ligulate. Involucre cartilaginous or scarious; phyllaries imbricate, pluriseriate. Receptacle usually paleaceous or bearing long bristles or hairs. Flowers yellow or purplish, less commonly white. Style slightly thickened or with a ring of minute hairs near point of bifurcation. Anther bases mostly tailed. Achenes terete or compressed, unbeaked, or often with an umbo in the Cardunineae. Pappus scaly, bristly or hairy.
Jurinea: Perennial herbs, rarely suffrutescent or acaulous. Leaves unarmed, rosulate or alternate, entire, pinnatilobed or pinnatisect. Capitula homogamous, discoid, solitary to corymbose. Involucre cylindrical to globose; phyllaries (4-)5-6(-8) seriate, imbricate, linear to lanceolate (outer ones sometimes triangular), apex unarmed or spinulose, erect or recurved, adpressed to lax. Receptacle long bristly. Flowers lilac to purplish. Achenes narrowly obpyramidal, ± tetragonal, truncate above, with a membranous crown (coronula) around pappus base; umbo depressed barrel shaped or saucer shaped; hilum basal or nearly so. Pappus hairs stiff, pluriseriate, persistent, scabrous, barbellate or plumose, 2-3 innermost bristles longer and broader than rest. A difficult genus, particularly with regard to the species complex centred around J. mollis which needs population analysis and breeding studies.
