Trimezia

The rootstock is variously described as an elongated corm or a rhizome. Plants vary in height from about in the case of T. pusilla to in the case of T. spathata subsp. sincorana. Linear to lanceolate leaves grow from the base of the plant. Most species have flowers in some shade of yellow. The six tepals are arranged in two series. The outer tepals (sepals) are larger than the inner ones (petals); both may have brown-purple markings at the base. The stamens have free filaments (i.e. they not fused together or fused to the style). The style is divided into three branches, each of which usually has two lobes. ==Taxonomy==

The genus Trimezia was first published with an appropriate description by William Herbert in 1844. Trimezia is placed in the tribe Trimezieae of the subfamily Iridoideae. Lovo et al. (2018) consider these characteristics to be among those distinguishing their circumscription of Neomarica from the other genera into which they divide the tribe. Species , Plants of the World Online accepted about 80 species of Trimezia. However, this includes species that other sources place in different genera in the tribe Trimezieae. The placement in Lovo et al. (2018), where given in their paper, is shown in the second column. File:Lily flower.jpg|Trimezia candida (syn.

The genus is native to the warmer parts of southern Mexico, Central America, South America, Florida, and parts of the West Indies. Trimezia species typically grow in damp grassland. ==References==
