Description | Study of some early types of species now known to belong to the genus Tritonia Ker Gaw l.. a member of Iridaceae. subfamily Crocoideae, comprising some 28 species of southern and south tropical Africa, has shown the need for some nomen- clatural adjustments. Ixia undulata Burm.f. (1768) is an earlier name for T. crispa (L.f.) Ker Gawl. based on Gladiolus crispus L.f. (1782) and the combination T. undulata (Burm.f.) Baker must be used for the species, which is native to the western half of Western Cape, South Africa. The variety T. crispa var. parx iflora is also reduced to synonymy. The type specimen of Ixia gladiolaris Lam. (1789), currently considered a synonym of Tritonia securigera (Aiton) Ker Gawl.. has flowers that lack the characteristic tooth-like ridges on the lower tepals of the latter, and corresponds closely to the eastern southern African T. lineata (Salisb.) Ker Gawl., based on Gladiolus lineatus Salisb. (1796). The new combination T. gladiolaris (Lam.) Goldblatt J.C. Manning is made and T. lineata is reduced to synonymy. Montbretia lacerata and Tritonia lacerata. erroneously regarded as synonyms of T. crispa, are combinations based on Gladiolus laceratus Burm.f., a species that remains unidentified because no type is known and the description is too vague to permit its identification. Lastly, field studies have shown that the cnsped-leaved T. watermeveri is connected by a series of morphological intermediates to typical T. securigera. which has straight leaves and identical flowers. The new combination T. securigera subsp. watermeveri (L.Bolus) J.C.Manning Goldblatt is proposed for this taxon. | |
