Alisma lanceolatum | |
Alisma lanceolatum is a species of aquatic plant in the water plantain family known by the common names lanceleaf water plantain and narrow-leaved water plantain. [3] It is widespread across Europe, North Africa and temperate Asia. [4] It is naturalized in Australia, New Zealand, Oregon, California and British Columbia. It is considered a noxious weed in some places. [5] [6] [7] [8]
This species is a weed of rice fields in many areas, including New South Wales and California.
In England and Wales it is occasionally locally found, in Ireland it is rare, and Scotland it is very rare.
It is found in mud and in fresh waters.
This is a perennial herb growing from a caudex in the water or mud that typically reaches a height of about 0.7 meters and a spread of 0.25 meters. [9] It produces lance-shaped leaves 12 to 20 centimeters long and 4 wide on long petioles; leaves which remain submerged in water are smaller and less prominently veined. The inflorescence is mostly erect and up to half a meter tall.
It produces a wide array of small pinkish-purple three-petalled flowers that open in the morning, from June until August. [10] The fruit is a tiny achene up to 2 or 3 millimeters long clustered into an aggregate fruit of about 20 units. The seeds are reddish-brown and about 1.5 millimeters long. [4]
Grows best in water 15-30 centimeters deep in full sun. Suitable for USDA hardiness zones 5–8. [9]
The water plantain Alisma plantago-aquatica has acute leaf tips not tapering to a stalk. [11] The flowers of A. plantago-aquatica also typically open in the afternoon, and the leaves are wider. [10]
Plantago is a genus of about 200 species of flowering plants in the family Plantaginaceae, commonly called plantains or fleaworts. The common name plantain is shared with the unrelated cooking plantain. Most are herbaceous plants, though a few are subshrubs growing to 60 centimetres tall.
Alisma plantago-aquatica, also known as European water-plantain, common water-plantain or mad-dog weed, is a perennial flowering aquatic plant widespread across most of Europe and Asia, and apparently spread elsewhere in both the Old and New World.
Alisma is a genus of flowering plants in the family Alismataceae, members of which are commonly known as water-plantains. The genus consists of aquatic plants with leaves either floating or submerged, found in a variety of still water habitats around the world. The flowers are hermaphrodite, and are arranged in panicles, racemes, or umbels. Alisma flowers have six stamens, numerous free carpels in a single whorl, each with 1 ovule, and subventral styles. The fruit is an achene with a short beak.
Heteranthera limosa is an annual flowering plant in the water hyacinth family known by the common names ducksalad and blue mudplantain. It grows in shallow water or on mud. It is considered a threatened species in parts of the central United States, and an invasive species weed in California, where it is a nuisance in rice paddies. It is also occasional in Florida waterways.
Stellaria graminea is a species of flowering plant in the family Caryophyllaceae known by the common names common starwort, grass-leaved stitchwort, lesser stitchwort and grass-like starwort.
Alisma gramineum is a small aquatic plant in the water-plantain family. It has several common names including narrowleaf water-plantain, ribbonleaf water-plantain or ribbon-leaved water-plantain, and grass-leaved water-plantain. It grows in mud or submerged in shallow fresh or brackish water in marshy areas.
Stuckenia pectinata, commonly called sago pondweed or fennel pondweed, and sometimes called ribbon weed, is a cosmopolitan water plant species that grows in fresh and brackish water on all continents except Antarctica.
Potamogeton amplifolius, commonly known as largeleaf pondweed or broad-leaved pondweed, is an aquatic plant of North America. It grows in water bodies such as lakes, ponds, and rivers, often in deep water.
Alyssum desertorum is a species of flowering plant in the family Brassicaceae known by the common name desert madwort. It is native to Europe, North Africa and Asia, and it is found in parts of western North America as an introduced species and sometimes a weed. This is a hairy annual herb producing upright stems up to about 20 centimeters tall. The leaves are linear to oblanceolate-linear in shape, 0.5-4 millimeters long and 0.3-3 millimeters wide. The entire plant is covered by 8-20 rayed stellate trichomes, giving the plant a grayish appearance. It produces small yellowish flowers with petals that are 2-2.5 millimeters long and round, notched fruits 2.5-4.5 millimeters long. The brown seeds are winged, arranged two to a locule, and are about 1.5 millimeters long.
Najas marina is a species of aquatic plant known by the common names spiny water nymph, spiny naiad and holly-leaved naiad. It is an extremely widespread species, reported across Europe, Asia, Africa, Australia, the Americas and many oceanic islands. It can be found in many types of freshwater and brackish aquatic habitat, including bodies of alkaline water.
Plantago aristata is a species of plantain known by the common name bracted plantain or largebracted plantain. It is native to the eastern and central United States, and it can be found in other parts of North America as well as parts of Eurasia as an introduced species. It grows in many types of habitat, including disturbed areas, where it is a minor weed.
Alisma subcordatum, the American water plantain, is a perennial aquatic plant in the water-plantain family (Alismataceae). This plant grows to about 3 feet in height with lance to oval shaped leaves rising from bulbous corms with fibrous roots. Any leaves that form underwater are weak and quick to rot; they rarely remain on adult plants. A branched inflorescence with white to pink 3-petaled flowers blooms from June to September. The seeds are eaten by waterfowl and upland birds. Native Americans dried and ate the submerged rootlike structures. The species name subcordatum means "almost heart-shaped".
Alisma triviale, the northern water plantain, is a perennial semi-aquatic or aquatic plant in the water-plantain family (Alismataceae).
Sagittaria longiloba is a North American species of flowering plant in the water plantain family known by the common name longbarb arrowhead and Gregg arrowhead.

Plantago cordata is a species of flowering plant in the plantain family known by the common name heartleaf plantain. It is native to eastern North America, where it is distributed throughout eastern Canada and the eastern United States. Though it has a wide distribution, it is very localized, and populations have declined almost everywhere.
Damasonium minus is a species of flowering plant in the water-plantain family known by the common names starfruit and star-fruit. It is native to Australia, where it occurs everywhere except the Northern Territory. It is perhaps best known as an agricultural weed. It is a major weed of Australian rice crops.
