The Marsileaceae are a small family of heterosporous aquatic and semi-aquatic ferns, though at first sight they do not physically resemble other ferns. The group is commonly known as the "pepperwort family" or as the "water-clover family" because the leaves of the genus Marsilea superficially resemble the leaves of a four-leaf clover. In all, the family contains 3 genera and 50 to 80 species with most of those belonging to Marsilea.
Vallisneria is a genus of freshwater aquatic plant, commonly called eelgrass, tape grass or vallis. The genus is widely distributed in tropical and subtropical regions of Asia, Africa, Europe, and North America.
Aponogeton madagascariensis is commonly known as Madagascar laceleaf, lattice leaf or lace plant. It is an aquatic plant native to Madagascar, popularly sold for use in aquariums. It is endangered in the wild.
Anubias is a genus of aquatic and semi-aquatic flowering plants in the family Araceae, native to tropical central and western Africa. They primarily grow in rivers and streams, but can also be found in marshes. They are characterized by broad, thick, dark leaves that come in many different forms. The genus was revised in 1979 and since then its nomenclature has been stable. Species can be determined by using mostly characteristics of the inflorescence. Because of the often shady places where the plants grow, the genus was named after the Egyptian god Anubis, the god of the afterlife. The genus was first described in 1857 by Heinrich Wilhelm Schott, with A. afzelii as its type species.
Echinodorus cordifolius, the spade-leaf sword or creeping burhead, is a species of aquatic plants in the Alismatales. It is native to Mexico, the West Indies, Central America, South America and the southeastern United States.
Echinodorus macrophyllus is a species of aquatic plants in the Alismataceae. It is native to Brazil and Bolivia.
Leptochilus pteropus, synonym Microsorum pteropus, commonly known as Java fern after the Indonesian island of Java, can be found in Malaysia, Thailand, Northeast India and some regions of China. It is a highly variable plant with several different geographic varieties that vary in leaf size and shape. Found in its natural habitat growing attached to roots and rocks, it can grow in both fully and partially submerged environs. The plant can propagate through small adventitious plants formed on older leaves, which attach themselves to hard substrates.
Aponogeton crispus is an aquatic plant species.
Ceratopteris thalictroides is a fern species belonging to the genus Ceratopteris, one of only two genera of the subfamily Parkerioideae of the family Pteridaceae.
Azolla cristata , the Carolina mosquitofern, Carolina azolla or water velvet, is a species of Azolla native to the Americas, in eastern North America from southern Ontario southward, and from the east coast west to Wisconsin and Texas, and in the Caribbean, and in Central and South America from southeastern Mexico (Chiapas) south to northern Argentina and Uruguay.
Bolbitis is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016.
Crinum thaianum, Common name Thai Onion plant or Water onion, is an emergent plant species endemic to coastal plain of southern Thailand in Ranong and Phang Nga Provinces. Its natural habitat is along the banks of running streams, where its roots and bulb are submerged but the flowering holds the umbel of large, showy flowers above the surface. This natural habits make it a wonderful addition for tropical aquaria, and it is sold in many lands to be used in decorating displays of tropical fish. In nature, however, the species is threatened and diminishing in numbers due to habitat destruction.
Aponogeton longiplumulosus is a submerged aquatic plant that is native to Madagascar. It possesses an elongated rhizome 2–3 cm in diameter. The leaves are an olive green-brown, 8 - 14 inches (20–35 cm) long and 2.5 inches (6 cm) broad, with a fluted margin and a petiole up to about 24 inches (60 cm) long. No floating leaves are formed. New leaf colour forms have been introduced recently. The flowers are a dark violet in colour.
Cryptocoryne beckettii, also known as Beckett's water trumpet, is a plant species belonging to the Araceae genus Cryptocoryne.
Nymphaea nouchali, often known by its synonym Nymphaea stellata, or by common names blue lotus, star lotus, red and blue water lily, blue star water lily or manel flower is a water lily of genus Nymphaea. It is native to southern and eastern parts of Asia, and is the national flower of Bangladesh and Sri Lanka. In Sanscrit it is utpala. This species is sometimes considered to include the blue Egyptian lotus Nymphaea caerulea. In the past, taxonomic confusion has occurred, with the name Nymphaea nouchali incorrectly applied to Nymphaea pubescens.
Bolbitis heteroclita is an aquatic fern species of Bolbitis, native to the Indochina region of tropical Southeast Asia.
Anubias afzelii is a species belonging to the Aroid genus Anubias. It was first described scientifically by Heinrich Wilhelm Schott in 1857, based on material collected in Sierra Leone by Adam Afzelius, after whom the species was named. The genus Anubias was described simultaneously, with only A. afzellii belonging to it, which therefore is the type species of the genus. No other species currently placed in the genus Anubias was described earlier and A. afzelii was therefore the first species of this genus known to science.
Anubias gigantea is a species belonging to the Aroid genus Anubias. It was first mentioned by Auguste Chevalier in 1920, based on material that he had collected in Guinea. The formal description followed in 1939 by John Hutchinson. It is closely related to A. afzelii, basically only differing from that species by the form of the leaf-blade.
Fontinalis antipyretica, greater water-moss, or common water moss, is a species of submerged aquatic moss belonging to the subclass Bryidae. It is found in both still and flowing freshwater in Europe, Asia, Greenland and Africa. In North America it is found in most Canadian provinces with a seaboard and most US states except the most southern.
Marsilea minuta, or dwarf waterclover is a species of aquatic fern in the family Marsileaceae. It is not to be confused with Marsilea minutaE.Fourn. 1880, which is a synonym for Marsilea vestita. Other common names include gelid waterklawer, small water clover, airy pepperwort, and pepperwort, though the lattermost also applies to plants in the genus Lepidium. In French it is called marsilea à quatre feuilles and petite marsilée, the latter appearing to be a calque with the Latin botanical name. In Chinese it is 南国田字草, literally "southern field word grass," referencing the similarity of the leaflet shape to the Chinese character for "field." The Koch Rajbongshi people and Garo people call it shusni shak. It is called 'শুশনি শাক' in Bengali. In parts of India it can be called sunisanakka In Indonesian it is semanggi, but this name also applies to Marsilea crenata. In Japanese it is nangokudenjiso and in Thai it is phakwaen. In Malaysian it is tapak itek. In the Philippines it is kaya-kayapuan.
