12. S. inaequidens DC. , Prodr. 6: 401 (1837).

Like 11 but stems less densely leafy; leaves mostly c. 0- 1 cm wide, linear, usually entire; supplementary bracts 10-20, with conspicuous, white, scarious, fimbriate margins. Naturalized in N. Italy and parts of W. Europe. [Be Ga It.] (South Africa.)

The identity of the plant naturalized in Europe has long been in doubt; it has been called S. harveianus MacOwan , and, quite erroneously, S. lautus Solander ex Willd. It now seems most probable that it is S. inaequidens DC. , although further work on the group in South Africa may lead to some change of opinion.

S. longifolius L. , Sp. Pl. ed. 2, 1222 (1763), also from South Africa, is perhaps becoming naturalized in S.E. France; it is similar to 11 but has the involucre c. 4 mm and only 5 ligules c. 4 mm long.
