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 seasonal flowering plants in the family Iridaceae comprising about 100 species of perennials growing from corms. They are low growing plants, whose flower stems remain underground, that bear relatively large white, yellow, orange or purple flowers and then become dormant after flowering. Many are cultivated for their flowers, appearing in autumn, winter, or spring. The flowers close at night and in overcast weather conditions. The crocus has been known throughout recorded history, mainly as the source of saffron. Saffron is obtained from the dried stigma of Crocus sativus, an autumn-blooming species. It is valued as a spice and dyestuff, and is one of the most expensive spices in the world. Iran is the center of saffron production. Crocuses are native to woodland, scrub, and meadows from sea level to alpine tundra from the Mediterranean, through North Africa, central and southern Europe, the islands of the Aegean, the Middle East and across Central Asia to Xinjiang in western China. Crocuses may be propagated from seed or from daughter cormels formed on the corm, that eventually produce mature plants. They arrived in Europe from Turkey in the 16th century and became valued as an ornamental flowering plant.
Iridaceae is a family of plants in order Asparagales, taking its name from the irises. It has a nearly global distribution, with 69 accepted genera with a total of c. 2500 species. It includes a number of economically important cultivated plants, such as species of Freesia, Gladiolus, and Crocus, as well as the crop saffron.
Sophora is a genus of about 45 species of small trees and shrubs in the pea family Fabaceae. The species have a pantropical distribution. 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 hairs on their drooping sepals, also called their falls.
Tigridia, is a genus of bulbous or cormous flowering plants belonging to the family Iridaceae. With common names including peacock flowers, tiger-flowers or shell flowers, they have large showy flowers; and one species, Tigridia pavonia, is often cultivated for this. The approximately 60 species in this family grow in the Americas, from Mexico down to Chile.
Hymenocallis (US) or (UK) is a genus of flowering plants in the amaryllis family native to the Americas.
Crocoideae is one of the major subfamilies in the family Iridaceae.
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.
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.
Cypella is a genus of herbaceous, perennial and bulbous plants in the family Iridaceae. It is distributed in South America, from Peru and Brazil to Northern Argentina. The genus name is likely derived from the Greek word kyphella, meaning "hollow of the ear", and alludes to the shape of the inner tepals.
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".
Rhodolirium is a small South American genus in the tribe Hippeastreae of the family Amaryllidaceae. Although originally described by Philippi in 1858 it has long remained buried in other taxa, principally Hippeastrum and more recently Rhodophiala. Only in recent years has it been rehabilitated.
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.
Crocus biflorus, the silvery crocus or scotch crocus, is a species of flowering plant in the family Iridaceae. It is native to south-eastern Europe and south-western Asia, including Italy, the Balkans, Ukraine, Turkey, Caucasus, Iraq, and Iran. It is a cormous perennial growing to 6 cm (2.4 in) tall and wide. It is a highly variable species, with flowers in shades of pale mauve or white, often with darker stripes on the outer tepals. The flowers appear early in spring.
Hippeastrinae is a subtribe of plants classified under the tribe Hippeastreae. It belongs to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae).
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.
Trimezia candida, synonym Neomarica candida, also known as white walking iris, is species of flowering plant. It was first described by Emil Hassler and given the name Neomarica candida by Thomas Archibald Sprague. Trimezia candida belongs to the genus Trimezia and family Iridaceae.
