Description
Summary:Alophia veracruzana is a new species of this American genus of Iridaceae subfamily Iridoideae. Closely related to the widespread A. drummondii, it differs in its pale to dark lilac-blue perianth with white to yellow markings, secund flower, and more or less erect inner tepals with lightly raised marginal areas bordering a smooth median zone. The generic characters of Alophia lie exclusively in its stamens and style, and the genus is defined by pandurate, nearly latrorse anthers, and deeply, but incompletely divided style branches with slender, ascending-recurved, terminally stigmatic style arms. The relationships of Alophia within tribe Tigridieae are uncertain, and its suggested affinities with Tigridia (Tigridiinae) seem unlikely. Despite a similar and derived karyotype with n = 14, and comparable forked style branches, the pollen grains of Alophia are not bisulcate as they are in all other Tigridiinae.
