Trimezia martinicensis is a species of bulbous plant in the family Iridaceae. Originally from South America and the West Indies, it is now widely naturalized throughout the tropics.[1][2] Common names include Martinique trimezia,[3] yellow walking iris[4] and forenoon yellow flag.[5]
Distinction from Trimezia steyermarkii
Trimezia martinicensis is closely related to T. steyermarkii,[6] with which it has been widely confused.[7] Clive Innes describes T. martinicensis as having a brown mark at the base of each outer tepal, whereas T. steyermarkii has brownish-purple bands.[8] In Kubitzki & Huber (1998), the flowers of T. martinicensis are shown as opening less widely than those of T. steyermarkii. The inner tepals of both species are S-shaped in cross-section; those of T. martinicensis are more-or-less upright (Innes describes them as "folded inwards"[9]), whereas those of T. steyermarkii bend outwards into a more elongated shape so that the top of the S is not visible from above.[10] A diagnostic feature is that the style crests of T. martinicensis are short, whereas those of T. steyermarkii are longer,[10] about 3–4 mm (0.12–0.16 in) long, comparable in length to its anthers, which are about 4 mm (0.16 in) long.[11] Another difference is that the leaves of T. martinicensis are narrower, only about 1.3 cm (0.5 in) wide, whereas those of T. steyermarkii are 2.5–3.4 cm (1.0–1.3 in) wide.[12]
