Stylidium fissilobum is a dicotyledonous plant that belongs to the genus "Stylidium" (family Stylidiaceae).
 It is an annual plant that grows from 5 to 50 cm tall.
 Linear or deltate leaves, about 4-34 per plant, are scattered along the elongate, glabrous stem.
 The leaves are generally 1–6 mm long and 0.3-0.7 mm wide.
 Petioles and scapes are absent.
 Inflorescences are 3–18 cm long.
 Flowers are pink, white, or mauve and bloom from March to July in the southern hemisphere.
 "S. fissilobum"'s wide distribution ranges across northern Australia from the western Kimberley region and Northern Territory eastward as far as Mount Surprise in Queensland.
 Its habitat is recorded as being wet sands at swamp edges in association with grasslands and sedgelands.
 Due to its weak stem, this species often threads its way through supporting branches and leaves of the dense grass and sedge cover.
 "S. fissilobum" is most closely related to "S. aquaticum" and "S. oviflorum".
 Its conservation status has been assessed as data deficient.
Pleiacanthus is a monotypic genus of flowering plants in the aster family containing the single species Pleiacanthus spinosus (formerly "Stephanomeria spinosa"), which is known by the common name thorn skeletonweed, or thorny skeletonweed.
 It is native to the western United States from Montana and Idaho to southern California and Arizona, where it grows in many types of mostly dry habitat from deserts to mountains.
 It is a spindly subshrub producing several slender stems up to 40 or 50 centimeters tall from a woody caudex.
 The stems divide many times into short, rigid branches which narrow to sharp thorn-tips.
 The plant is mostly hairless except for brownish woolly tufts at the base and below the basal leaves.
 The leaves are small and linear on the lower stem, and reduced to scale-like growths on the upper branches.
 Flower heads occur near the ends of the branches.
 Each has a cylindrical base wrapped in one layer of phyllaries.
 The head contains 3 to 5 ray florets, each with an elongated tube and a pale to bright pink ligule.
 The fruit is an achene tipped with a cluster of pappus bristles which are not plumelike as are those of the "Stephanomeria" species with which this plant was once classified.
Euphorbia trigona (also known as African milk tree, cathedral cactus, Abyssinian euphorbia, and high chaparall ) is a perennial plant that originally comes from Central Africa.
 It has an upright stem that is branched into three or four sides.
 The stem itself is dark green with V-shaped light green patterns.
 The about 5mm long thorns are placed in pairs of two on the stem's ridges.
 The drop shaped leaves grow from between the two thorns on each ridge.
 The plant has never been known to flower, and is possibly a hybrid.
 As with many other "Euphorbia" species, the latex from the plant is poisonous and can cause skin irritations.
 The trigona can withstand brief cold temperatures of up to -3 degrees.
 It prefers sandy soil but can withstand most types of soil, provided it is well draining.
 It can root very easily from stem cuttings, if allowed to dry for 3-7 days before planting so that it can form a callus and not rot.
 It grows from 1.5 - 3 meters.
 It is a pest-free plant.
 A problem that some trigonas face is that they are susceptible to falling over when fully grown because of their shallow and small root system
Rorippa palustris is a species of flowering plant in the mustard family.
 It is widespread and native to parts of Africa, and much of Asia, Europe and Eurasia, North America and the Caribbean.
 It can also be found in other parts of the world as an introduced species and a common weed, for example, in Australia and South America.
 It is an adaptable plant which grows in many types of damp, wet, and aquatic habitat.
 It may be an annual, biennial, or perennial plant, and is variable in appearance as well.
 It produces an erect stem, sometimes with branches, attaining a maximum height of just over one meter.
 The leaves are up to 30 centimeters long and have toothed to deeply lobed edges.
 The inflorescence is a raceme of mustardlike flowers with spoon-shaped yellow petals each a few millimeters in length.
 The fruit is a dehiscent and smoothly valved silicle, up to a centimeter long, and containing anywhere from 20 to 90 minute seeds.
Rorippa austriaca is a species of flowering plant in the mustard family known by the common names Austrian yellow-cress and Austrian fieldcress.
 It is native to parts of Europe and Asia, and it is known in North America as an introduced species and sometimes a noxious weed.
 It can grow in disturbed habitat, such as roadsides, and in very wet habitat such as mudflats.
 It is a perennial herb growing upright to erect, reaching a maximum height near one meter.
 The branching stem bears hairless blue-green lance-shaped leaves up to 10 centimeters long.
 The bases of the upper leaves clasp the stem.
 The inflorescence is a raceme at the top of the stem and the ends of stem branches.
 The mustardlike flowers have small yellow petals.
 The fruit is a plump silique a few millimeters long, but many plants do not fruit and seed production is rare.
 Reproduction in this species is more often vegetative, the plants concentrating their growth in belowground tissue and spreading clonally.
 The root system of the plant is particularly aggressive, sending up many new plants as it spreads.
Stephanomeria elata is a species of flowering plant in the aster family known by the common names Santa Barbara wirelettuce and Nuttall's wirelettuce.
 It is native to Oregon and California, where it grows in coastal and inland mountain ranges, including the Sierra Nevada.
 It can be found in many types of habitat.
 It is an annual herb producing a slender, erect stem often exceeding one meter in maximum height.
 It is hairy to hairless and often glandular.
 The leaves are mostly located in a basal rosette, the largest reaching 10 centimeters long.
 Smaller, much-reduced leaves occur farther up the stem.
 The leaves drop early, leaving the plant naked for most of the year.
 Flowers occur singly or in small clusters along the stiff branches.
 Each head contains up to 15 or 16 ray florets, each with an elongated tube and a pink ligule 6 or 7 millimeters long.
 The fruit is an achene tipped with a spreading cluster of long, plumelike pappus bristles.
In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species.
 In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height.
 Trees are not a taxonomic group but include a variety of plant species that have independently evolved a woody trunk and branches as a way to tower above other plants to compete for sunlight.
 Trees tend to be long-lived, some reaching several thousand years old.
 In looser definitions, the taller palms, tree ferns, bananas and bamboos are also trees.
 Trees have been in existence for 370 million years.
 It is estimated that there are just over 3 trillion mature trees in the world.
Stephanomeria diegensis is a species of flowering plant in the aster family known by the common name San Diego wirelettuce.
 It is native to the coastal hills and ranges of southern California and Baja California, where it grows in many types of open habitat.
 It evolved as a hybrid of "Stephanomeria exigua" and "S. virgata".
 Furthermore, it is thought to be the result of homoploid hybrid speciation, which is uncommon.
 The plant is frequently misidentified as one of its parents, especially if older taxonomic keys are used.
 This is an erect annual herb easily exceeding two meters in height.
 Its slender stem has many spreading branches.
 The basal leaves are linear to lance-shaped and up to 10 centimeters long.
 The leaves wither early and are absent for most of the year, giving the plant a twiglike appearance.
 Leaves on the upper stem are small and reduced.
 The inflorescences are usually clusters of flower heads located at intervals on the stiff branches.
 Each head has a cylindrical base lined with phyllaries.
 These are often glandular.
 The head contains several ray florets, each with an elongated tube and a white or pink-tinged ligule measuring around a centimeter long.
 The fruit is a grooved achene tipped with a spreading cluster of long, plumelike pappus bristles.
Maquira is a genus of trees in the Moraceae family, native to South America.
Stylidium dunlopianum is a dicotyledonous plant that belongs to the genus "Stylidium" (family Stylidiaceae).
 It is an erect perennial plant that grows from 15 to 50 cm tall.
 Obovate leaves, about 6-12 per plant, form a basal rosette with some scattered along the stem.
 The leaves are generally 20–60 mm long and 7–19 mm wide.
 This species generally has one to five scapes and cymose inflorescences that are 13–40 cm long.
 Flowers are pink or mauve.
 "S. dunlopianum"'s distribution ranges from the Mitchell River area in Western Australia east to the Kakadu National Park in the Northern Territory.
 Its typical habitats include sandy or black organic soils along creekbanks, near rainforests, or in seepage areas in "Melaleuca leucadendra" swamps.
 It flowers in the southern hemisphere from May to November.
 "S. dunlopianum" is most closely related to "S. rotundifolium", but differs most significantly by its thickened stem base and growth habit.
 "S. dunlopianum" is a perennial whereas "S. rotundifolium" is an annual.
 Its conservation status has been assessed as data deficient.
