Nymphoides crenata, commonly known as wavy marshwort, is an aquatic perennial herb of the family Menyanthaceae endemic to Australia, [4] found in all mainland states and the Northern Territory [5] [6] [7]
It is a stoloniferous, floating, perennial with stems up to 3 m long. The petioles of the basal leaves are from 8–42 cm long. The leaf lamina are ovate to circular, and deeply cordate and vary from 3 to 15 cm in length. The stem leaves are smaller, and sometimes kidney-shaped. The flowers heterostylous, (see the gallery) and there can be from 8 to14 in clusters subtended by 1–4 stem leaves, or sometimes in spaced pairs along a short inflorescence. The calyx is from 5.5 to 16 mm long and the corolla from 20 to 50 mm in diameter. There are usually 4 lobes (sometimes 4 or 6) and there are usually 5 stigmas (but from 2-5). [6]
It grows on floodplains, [8] in swamps, lagoons, irrigation channels, and also in temporarily inundated depressions, [6] and in slow-flowing streams where the depth of the water is up to about 1.5 m deep, usually on mud, and it will persist on drying mud. [4]
Nymphoides crenata was first described as Limnanthemum crenatum in 1854 by Ferdinand von Mueller. [1] [9] In 1891, Otto Kuntze transferred it to the genus, Nymphoides . [1] [2]
Nymphoides, or floatingheart, is a genus of aquatic flowering plants in the family Menyanthaceae. The genus name refers to their resemblance to the water lily Nymphaea. Nymphoides are aquatic plants with submerged roots and floating leaves that hold the small flowers above the water surface. Flowers are sympetalous, most often divided into five lobes (petals). The petals are either yellow or white, and may be adorned with lateral wings or covered in small hairs. The inflorescence consists of either an umbellate cluster of flowers or a lax raceme, with internodes occurring between generally paired flowers.
Teucrium is a cosmopolitan genus of flowering plants in the family Lamiaceae, commonly known as germanders. Plants in this genus are perennial herbs or shrubs, with branches that are more or less square in cross-section, leaves arranged in opposite pairs, and flowers arranged in thyrses, the corolla with mostly white to cream-coloured, lobed petals.

Plants in the genus Mirbelia are prickly, perennial shrubs with simple, sometimes sharply-pointed leaves, or the leaves absent. The flowers are arranged singly or in groups in leaf axils or on the ends of branches, the sepals joined at the base with five teeth. The petals are usually red, orange, purplish or bluish and the fruit is an inflated pod.
Asterolasia is a genus of seventeen species of erect or prostrate shrubs in the family Rutaceae, and is endemic to Australia. The leaves are simple and arranged alternately, the flowers arranged in umbel-like groups on the ends of branchlets or in leaf axils, usually with five sepals, five petals and ten to twenty-five stamens. There are seventeen species and they are found in all Australian mainland states but not in the Northern Territory.
Xanthosia is a genus of flowering plants in the family Apiaceae and is endemic to Australia. It comprises 20 species of shrubs endemic to Australia. Plants in the genus Xanthosia are perennial herbs or small shrubs, the leaves divided, toothed or lobed,, the flowers white, pinkish or pale green and usually arranged in a compound umbel.

According to Plants of the World Online, Rumex vesicarius is native to tropical and temperate Asia, Africa, and Western Australia. However, the Council of Heads of Australasian Herbaria asserts that within Australia it is naturalised in Western Australia, the Northern Territory, South Australia, Queensland and New South Wales.
Polygala linariifolia is a species of flowering plant in the milkwort family (Polygalaceae). It extends worldwide, including in the Australian states of New South Wales, Queensland, Northern Territory and Western Australia, however due to obscure taxonomic classifications and similarities and cross-overs between other Polygala species, it is difficult to confirm the exact identity of P. linariifolia and its distribution across the world including Australia.
