Restionales is an order of flowering plants. [1] [2] In the Cronquist system (of 1981) it is used for an order (in subclass Commelinidae ) and circumscribed as:
The APG II system (2003) assigns the plants involved to the order Poales .
The Poales are a large order of flowering plants in the monocotyledons, and includes families of plants such as the grasses, bromeliads, rushes and sedges. Sixteen plant families are currently recognized by botanists to be part of Poales.
Monocotyledons, commonly referred to as monocots, are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf, or cotyledon. They constitute one of the major groups into which the flowering plants have traditionally been divided; the rest of the flowering plants have two cotyledons and are classified as dicotyledons, or dicots.
The Bromeliaceae are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, Pitcairnia feliciana.
LiliopsidaBatsch is a botanical name for the class containing the family Liliaceae. It is considered synonymous with the name monocotyledon. Publication of the name is credited to Scopoli : see author citation (botany). This name is formed by replacing the termination -aceae in the name Liliaceae by the termination -opsida.
Zygophyllaceae is a family of flowering plants that contains the bean-caper and caltrop. The family includes around 285 species in 22 genera.
The Restionaceae, also called restiads and restios, are a family of flowering plants native to the Southern Hemisphere; they vary from a few centimeters to 3 meters in height. Following the APG IV (2016): the family now includes the former families Anarthriaceae, Centrolepidaceae and Lyginiaceae, and as such includes 51 genera with 572 known species. Based on evidence from fossil pollen, the Restionaceae likely originated more than 65 million years ago during the Late Cretaceous period, when the southern continents were still part of Gondwana.
The Typhaceae are a family of flowering plants, sometimes called the cattail family. The botanical name for the family has been recognized by most taxonomists.
The Xyridaceae are a family of flowering plants. This family has been recognized by many taxonomists and is known as the yellow-eyed grass family.
The Thurniaceae are a family of flowering plants composed of two genera with four species. The botanical name has been recognized by most taxonomists.
In plant taxonomy, commelinids is a clade of flowering plants within the monocots, distinguished by having cell walls containing ferulic acid.
The Rapateaceae are a family of flowering plants. The botanical name has been recognized by most taxonomists.
Hydatellaceae are a family of small, aquatic flowering plants. The family consists of tiny, relatively simple plants occurring in Australasia and India. It was formerly considered to be related to the grasses and sedges, but has been reassigned to the order Nymphaeales as a result of DNA and morphological analyses showing that it represents one of the earliest groups to split off in flowering-plant phylogeny, rather than having a close relationship to monocots, which it bears a superficial resemblance to due to convergent evolution. The family includes only the genus Trithuria, which has at least 13 species, although species diversity in the family has probably been substantially underestimated.
The Ecdeiocoleaceae comprise a family of flowering plants with two genera and three species. The botanical name has rarely been recognized by taxonomists.
Flagellaria is the sole genus in the flowering plant family Flagellariaceae with only five species. The family has historically been recognized by few taxonomists. The APG II system, of 2003, does recognize such a family, and assigns it to the order Poales in the clade commelinids, in the monocots.
The Joinvilleaceae are a family of flowering plants with a single genus including four species. The APG II system, of 2003 assigns it to the order Poales in the clade commelinids in the monocots. The family consists of one genus with four currently accepted species, distributed from the Malay Peninsula to the Caroline Islands and high islands in the Pacific Ocean. It is evolutionarily significant as a relictual group closely related to grasses. They closely resemble large grass plants, in both general appearance and microanatomy, but possess fleshy fruits.
Trithuria is a genus of small ephemeral aquatic herb that represent the only members of the family Hydatellaceae found in India, Australia, and New Zealand. All of the 13 formally characterized species of Trithuria are found in Australia, with the exception of T. inconspicua and T. konkanensis, which are found in New Zealand and India, respectively. Until DNA sequence data and a reinterpretation of morphology proved otherwise, these plants were believed to be monocots related to the grasses (Poaceae). They are unique in being the only plants besides two members of Triuridaceae in which the stamens are in the center of the flower while the pistils surround them; in Hydatellaceae the resulting 'flowers' may instead represent condensed inflorescences or non-flowers.
Empodisma minus, commonly known as (lesser) wire rush or spreading rope-rush, is a perennial evergreen belonging to the southern-hemisphere family of monocotyledonous plants Restionaceae. The Latin name Empodisma minus translates to “tangle-foot” “small”. E. minus is found from Queensland to South Australia, Tasmania and throughout New Zealand south of 38 ° latitude, or the central north island. Its current conservation status is “Least concern”. In 2012, the new species Empodisma robustum was described in New Zealand, with what was previously described as E. minus from the lowland raised bogs of Waikato and Northland now being re-classified as E. robustum. E. minus remains an important peatformer in the south of New Zealand and in high altitude peatlands.
Ecdeiocolea is a genus of grass-like plants from Western Australia. It was first defined by von Mueller in 1874. Ecdeiocolea contains two species. The genus is a member of the small family Ecdeiocoleaceae and its type species is the widespread Ecdeiocolea monostachyaF.Muell.
The graminid clade is a clade of plants in the order Poales uniting four families, of which the grasses (Poaceae) are the most species-rich. Its sister group is the restiid clade.
Triodia scariosa, is more commonly known as porcupine grass or spinifex, and belongs to the endemic Australian grass genus Triodia. The species is perennial and evergreen and individuals grow in mounds, called hummocks, that reach up to ~1m in height. The leaves are ~30 cm long, 1mm in diameter, needlepointed and rigid, and its inflorescence is a narrow, loose panicle that forms a flowering stalk up to ~2m in height. The name is derived from Latin; Triodia refers to the three-toothed lobes of the lemma, and scariosa is in reference to the thin, dry glume. The species is common to Mallee (MVG14) and Hummock grassland (MVG20) communities, in arid and semi-arid regions of Australia.
