Trimezia is a genus of flowering plants in the family Iridaceae, native to the warmer parts of southern Mexico, Central America, South America, Florida, and the West Indies. [2] Trimezia is placed in the tribe Trimezieae. The division of the tribe into genera has varied considerably. In one approach, it contains only the genus Trimezia, which then includes the genera Neomarica, Pseudotrimezia and Pseudiris. In other approaches, two to five genera are recognized, sometimes also including the genus Deluciris .
The English names walking iris, apostle's iris and apostle plant have been used for many species, regardless of the generic placement (e.g. for Trimezia gracilis , syn. Neomarica gracilis). New plantlets form at the end of the flower spikes; after flowering, the spikes fall over and a new plant grows, so the plant "walks". Names including "apostle" refer to the incorrect belief that plants do not flower until 12 or more leaves are present. [3]
The rootstock is variously described as an elongated corm or a rhizome. Plants vary in height from about 7 cm (2.8 in) in the case of T. pusilla to 1.6 m (5.2 ft) 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. [4]
The genus Trimezia was first published with an appropriate description by William Herbert in 1844. [5] Herbert attributed the name to Salisbury, whose use he described as "absque charactere" ('without character'). [6] The genus name is derived from the Greek words tri, meaning "three", and meze, meaning "greater". [7]
Trimezia is placed in the tribe Trimezieae of the subfamily Iridoideae. [8] The number of genera into which the tribe is divided has varied considerably. Three genera were used before 2008: Trimezia, Neomarica and Pseudotrimezia. Some sources used all three; others combined Trimezia and Neomarica but retained Pseudotrimezia. [8] A further genus, Pseudiris, was published in 2008. Molecular phylogenetic studies have shown that although the tribe is monophyletic, the genera as traditionally used, based on morphological characteristics, are not. Three of the four main clades found in these analyses combine species from more than one genus. [9] [8] One response to these findings, adopted as of May 2019 [update] by Plants of the World Online and the World Checklist of Selected Plant Families, is to combine genera; thus Neomarica, Pseudiris and Pseudotrimezia are all placed within Trimezia. [1] An alternative approach, retaining the traditional genera but with changed circumscriptions, was put forward in 2018; an additional new genus, Deluciris , was also created within the tribe. [8]

When Trimezia was distinguished from Neomarica prior to molecular phylogenetic studies, i.e. entirely on morphological grounds, some vegetative characters were considered diagnostic. Trimezia in this sense always grows from corms, Neomarica almost always from rhizomes. Trimezia has flowering stems (scapes) that are circular in cross-section, whereas Neomarica has flattened scapes. [10] 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. [8]
As of May 2019 [update] , the World Checklist of Selected Plant Families accepted about 80 species of Trimezia. [11] 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.

Some former species which are now regarded as synonyms include: [11]
The genus is native to the warmer parts of southern Mexico, Central America, South America, Florida, and parts of the West Indies. [1] Trimezia species typically grow in damp grassland. [12]
Crocus is a genus of flowering plants in the iris family comprising 90 species of perennials growing from corms. Many are cultivated for their flowers appearing in autumn, winter, or spring. The spice saffron is obtained from the stigmas of Crocus sativus, an autumn-blooming species. Crocuses are native to woodland, scrub, and meadows from sea level to alpine tundra in North Africa and the Middle East, central and southern Europe, in particular Krokos, Greece, on the islands of the Aegean, and across Central Asia to Xinjiang Province in western China.
Sparaxis is a genus of flowering plants called the harlequin flowers. It belongs to the iris family Iridaceae with about 13 species endemic to Cape Province, South Africa.
Iridaceae is a family of plants in order Asparagales, taking its name from the irises, meaning rainbow, referring to its many colours. There are 66 accepted genera with a total of c. 2244 species worldwide. It includes a number of other well known cultivated plants, such as freesias, gladioli and crocuses.
Brodiaea, also known by the common name cluster-lilies, is a monocot genus of flowering plants of the family Themidaceae, in the order Asparagales.
Sisyrinchium is a large genus of annual to perennial flowering plant in the family Iridaceae. Native to the New World, the species are known as blue-eyed grasses and, though not true grasses and in varieties with flower colors other than blue, are monocots.
Sophora is a genus of about 45 species of small trees and shrubs in the pea family Fabaceae. The species are native to southern Asia, Australasia, various Pacific islands, western South America, the western United States, Florida and Puerto Rico. The generic name is derived from sophera, an Arabic name for a pea-flowered tree.
Subgenus Limniris is one subgenus of beardless irises, which don't have hair on their drooping sepals, also called their falls.
Hymenocallis (US) or (UK) is a genus of American plants in the amaryllis family.
Nemastylis, or pleatleaf, is a genus of flowering plants in the family Iridaceae, first described as a genus in 1835. It is native to Mexico, Central America, and the southern part of the United States. The genus name is derived from the Greek words nema, meaning "thread", and stylos, meaning "pillar" or "rod".
Irideae is a tribe included in the well-known family Iridaceae. It contains many species in five genera which are widely distributed in the Old World. The tribe derives its name from Iris, which is the largest genus of the tribe.
Trimezieae is a tribe included in the subfamily Iridoideae of the family Iridaceae. It is the smallest tribe in this subfamily, containing only three closely related genera.
Alophia is a small genus of perennial, herbaceous and bulbous plants in the family Iridaceae. The genus comprise five known species that occur from the South-central United States as well as in Mexico, Central America, and parts of South America.
Calydorea is a small genus of perennial, herbaceous and bulbous plants in the family Iridaceae native to Mexico and South America. The plants in the genus are small with tunicated bulbs. The flowers are light blue, violet, white, or yellow, depending on the species, of which there are around twenty. Taxonomists considered that the already known genera Salpingostylis, Cardiostigma, Catila and Itysa are not enough different from each other to justify their taxonomic segregation and, for this reason, all of them are now included in Calydorea.
Cobana is a genus of herbaceous, perennial and bulbous plants in the family Iridaceae. A monotypic genus, it contains a single species, Cobana guatemalensis, distributed in Honduras and Guatemala.
Ennealophus is a genus of perennial, herbaceous and bulbous plants in the family Iridaceae. It consists in five species distributed from Ecuador to Northern Brazil and Northwest Argentina. The genus name is derived from the Greek words ennea, meaning "nine", and lophus, meaning "crest".
Hesperoxiphion is a genus of flowering plants in the family Iridaceae, first described as a genus in 1877. It is native to northwestern South America. The genus name is derived from the Greek words hesperos, meaning "western", and xiphos, meaning "sword".
Iris tuberosa is a species of tuberous flowering plant of the genus Iris, with the common names snake's-head, snake's-head iris, widow iris, black iris, or velvet flower-de-luce.
Pyrolirion, commonly known as fire lilies or flame lilies, is a small genus of herbaceous, bulb-forming South American plants in the Amaryllis family, native to Chile, Peru, and Bolivia.
Trimezia fosteriana is a species of bulbous plant in the family Iridaceae. Due to the attractive aspect of its leaves and exuberant and delicate yellow flowers, it is widely used in cities in South America for ornamental purposes and gardening. This species is easily confused with Trimezia longifolia, due to the similarity of its yellow flowers. However, the latter species, placed in the genus Neomarica by some sources, is distinguished by the presence of a flattened (leaf-like) flower stem.
Deluciris is a genus of flowering plant in the family Iridaceae, native to East Brazil. It was first described in 2018 by André Gil and Juliana Lovo.
