Treatment

Tragopogon porrifolius Linnaeus , Species Plantarum 2: 789. 1753.

"Habitat - - - –” RCN: 5781.

Lectotype ( Díaz de la Guardia & Blanca in Taxon 41: 549. 1992): Herb. Burser XV(2): 69, centre specimen ( UPS) .

Generitype of Tragopogon Linnaeus (vide Díaz de la Guardia & Blanca in Jarvis & al., Regnum Veg. 127: 95. 1993).

Current name: Tragopogon porrifolius L. ( Asteraceae ).

Note: Specific epithet spelled “porrifolium” in the protologue. Although T. pratensis L. has historically been treated as the generitype (e.g. by Britton & Brown, Ill. Fl. N.U.S. ed. 2, 3: 313. 1913; Green, Prop. Brit. Bot.: 177. 1930), Díaz de la Guardia & Blanca (in Jarvis & al., Regnum Veg. 127: 95. 1993) designated T. porrifolius as type in its place. They rejected the earlier choice on the grounds that T. pratensis has five involucral bracts, conflicting with the eight described in Linnaeus’ generic protologue.
