Tradescantia longipes, commonly known as the wild crocus [2] (although it is not closely related to plants in the genus Crocus ), is a perennial herbaceous plant in the dayflower family. It is found only in the Ozark Mountains of southern Missouri and northern Arkansas in the Midwest United States. A spring blooming species, its flowers can be observed from April to May, typically in its preferred habitat of wooded slopes on rocky hillsides. While most other members of the genus in North America have stems reaching at least a few inches above the soil, the flowering shoots of Tradescantia longipes are borne essentially at ground level. [3] This character is shared with some individuals of Tradescantia hirsuticaulis and Tradescantia virginiana , two closely related species, although both typically have obvious stems. [4] Regardless, Tradescantia longipes can be distinguished from the former with its longer pedicels and bracts without fine hairs, and from the latter by the presence of at least some glandular hairs on the sepals. Furthermore, Tradescantia longipes is a tetraploid, meaning it has four sets of chromosomes, while Tradescantia hirsuticaulis is diploid with only two sets. Tradescantia virginiana occurs in both diploid and tetraploid forms, although it is consistently tetraploid where its range overlaps with Trandescantia longipes. [5]

A phylogenetic study based on the chloroplast DNA regions of trnL-trnF and rpL16, two commonly used gene regions for determining relationships, was unable to convincingly resolve the recent history of the evolution of Tradescantia longipes, but does suggest that it is closely related to the "erect Tradescantia" (series Virginianae), which includes most of the other North American species. [6]

Tradescantia longipes can be grown as an ornamental plant for its showy flowers. It is considered especially suitable in rock gardens or native plant gardens, but may be grown in most situations so long as partial shade is provided. It is considered tolerant of nutrient poor soils, but prefers soils that are acidic, medium-moist, and well-drained. The plants grow in clumps that can be divided as desired. The leaves tend to die back after flowering ceases, and it is thus recommended that the plant be cut back to encourage new growth and potential re-flowering in the autumn. [7]

<span class="mw-page-title-main">Commelinaceae</span> Family of flowering plants

Commelinaceae is a family of flowering plants. In less formal contexts, the group is referred to as the dayflower family or spiderwort family. It is one of five families in the order Commelinales and by far the largest of these with about 731 known species in 41 genera. Well known genera include Commelina (dayflowers) and Tradescantia (spiderworts). The family is diverse in both the Old World tropics and the New World tropics, with some genera present in both. The variation in morphology, especially that of the flower and inflorescence, is considered to be exceptionally high amongst the angiosperms.

<i>Arisaema triphyllum</i> Species of flowering plant

Arisaema triphyllum, the Jack-in-the-pulpit, is a species of flowering plant in the arum family Araceae. It is a member of the Arisaema triphyllum complex, a group of four or five closely related taxa in eastern North America. The specific name triphyllum means "three-leaved", a characteristic feature of the species, which is also referred to as Indian turnip, bog onion, and brown dragon.

<i>Dactylis glomerata</i> Species of grass

Dactylis glomerata is a species of flowering plant in the grass family Poaceae, commonly known as cock's-foot, orchard grass, or cat grass (due to its popularity for use with domestic cats). It is a cool-season perennial C3 bunchgrass native throughout most of Europe, temperate Asia, and northern Africa.

<i>Physostegia virginiana</i> Species of flowering plant

Physostegia virginiana, the obedient plant, obedience or false dragonhead, is a species of flowering plant in the mint family, Lamiaceae. It is native to North America, where it is distributed from eastern Canada to northern Mexico. Physostegia are known commonly as obedient plants because a flower pushed to one side will often stay in that position. The name “false dragonhead” refers to the dragonheads of the related Dracocephalum, a genus to which the plant once belonged.

<i>Tradescantia virginiana</i> Species of flowering plant

Tradescantia virginiana, the Virginia spiderwort, is a species of flowering plant in the family Commelinaceae. It is the type species of Tradescantia, native to the eastern United States. It is commonly grown in many gardens and also found growing wild along roadsides and railway lines.

<i>Commelina benghalensis</i> Species of flowering plant

Commelina benghalensis, commonly known as the Benghal dayflower, tropical spiderwort, or wandering Jew, kanshira in Bengali, is a perennial herb native to tropical Asia and Africa. It has been widely introduced to areas outside its native range, including to the neotropics, Hawaii, the West Indies and to both coasts of North America. It has a long flowering period, from spring to fall in subtropical areas, and throughout the year closer to the equator. It is often associated with disturbed soils.

<i>Commelina virginica</i> Species of flowering plant

Commelina virginica, commonly known as the Virginia dayflower, is a perennial herbaceous plant in the dayflower family. It is native to the mideastern and southeastern United States, where it is typical of wet soils. While most members of the genus have thin, fibrous roots, the Virginia dayflower is relatively unique for its genus in having a perennial rhizome. The plant was first described by Carl Linnaeus in his 1762 publication of the second edition of Species Plantarum. A phylogenetic study based on the nuclear ribosomal DNA region 5S NTS and the chloroplast region trnL-trnF, two commonly used gene regions for determining relationships, suggested that Commelina virginica is most closely related to two African species, namely Commelina capitata and Commelina congesta. However, the statistical support for this result was low. Morphologically speaking the supposedly related species do share some unique traits. C. virginica and C. capitata have red hairs at the top of their leaf sheaths, an unusual character in the genus, while C. virginica and C. congesta both have clustered inflorescences on very short stalks.

Liatris bracteata, commonly known as the bracted blazing star, or South Texas gayfeather, is a species of flowering plant in the family Asteraceae.

<i>Streptolirion</i> Genus of flowering plants

Streptolirion is a genus of climbing monocotyledonous flowering plants in the dayflower family. It consists of a single species, namely Streptolirion volubile. It has a broad distribution in Asia, from China's western Hubei Province as well as the Russian Far East, Korea and Japan in the northeast, south to Vietnam and west to India. Currently two subspecies are accepted: S. volubile subsp. volubile and S. volubile subsp. khasianum, with the latter being a stronger climber covered with erect brown hairs. Streptolirion can be distinguished from the closely related climber Spatholirion by the former's two-seeded carpels and inflorescences that are all subtended by large involucral bracts. They bear yellow hairs below the anthers, which are believed to increase floral attraction by contrasting with the petals or suggesting additional pollen is present. Despite the large range, an analysis of chromosomes found major differences between Japanese and Indian populations, suggesting that additional species may be yet unrecognized.

<i>Spatholirion</i> Genus of flowering plants

Spatholirion is a genus of climbing or rosette monocotyledonous flowering plants in the dayflower family. It is distributed from China in the north, south to Thailand, Vietnam, and northern Peninsular Malaysia. It has four to eight seeds per carpel, unlike the closely related Streptolirion, which has only two, and white or purple petals. The inflorescence axis of Spatholirion longifolium and all of its branches are a bright purple, probably aiding in visual pollinator attraction. The genus was first described in 1896 by Henry Nicholas Ridley, the father of the commercial rubber industry, from plants sent to Kew Gardens from the Malay Peninsula near the border between Thailand and Malaysia. All species have a diploid chromosome number of 20.
