Oxalis or is a large genus of flowering plants in the wood-sorrel family Oxalidaceae comprising about 570 species. The genus occurs throughout most of the world, except for the polar areas; species diversity is particularly rich in tropical Brazil, Mexico and South Africa.
Oxalis acetosella, the wood sorrel or common wood sorrel, is a rhizomatous flowering plant in the family Oxalidaceae, common in most of Europe and parts of Asia. The specific epithet acetosella refers to its sour taste. The common name wood sorrel is often used for other plants in the genus Oxalis. In much of its range it is the only member of its genus and hence simply known as "the" wood sorrel. While common wood sorrel may be used to differentiate it from most other species of Oxalis, in North America, Oxalis montana is also called common wood sorrel. It is also known as Alleluia because it blossoms between Easter and Pentecost, when the Psalms which end with Hallelujah are sung.
Sourgrass is a common name given to several plant species which have a sour taste. Most are in fact not grasses:
Staphylococcus caprae is a Gram-positive, coccus bacteria and a member of the genus Staphylococcus. S. caprae is coagulase-negative. It was originally isolated from goats, but members of this species have also been isolated from human samples.
Cutworms are moth larvae that hide under litter or soil during the day, coming out in the dark to feed on plants. A larva typically attacks the first part of the plant it encounters, namely the stem, often of a seedling, and consequently cuts it down; hence the name cutworm. Cutworms are not worms, biologically speaking, but caterpillars.
Oxalis pes-caprae is a species of tristylous flowering plant in the wood sorrel family Oxalidaceae. Oxalis cernua is a less common synonym for this species.
Ipomoea pes-caprae, also known as bayhops, bay-hops, beach morning glory or goat's foot, is a common pantropical creeping vine belonging to the family Convolvulaceae. It grows on the upper parts of beaches and endures salted air. It is one of the most common and most widely distributed salt tolerant plants and provides one of the best known examples of oceanic dispersal. Its seeds float and are unaffected by salt water.
Goat's foot is a common name for several plants and may refer to:
Plasmodium caprae is a parasite of the genus Plasmodium subgenus Vinckeia.
Mycobacterium caprae is a species of bacteria in the genus Mycobacterium and a member of the Mycobacterium tuberculosis complex. Prior to 2003, the species was referred to as Mycobacterium tuberculosis subsp. caprae. It is also synonymous with the name Mycobacterium bovis subsp. caprae.
Oxalis stricta, called the common yellow woodsorrel, common yellow oxalis, upright yellow-sorrel, lemon clover, or more ambiguously and informally "sourgrass" or "pickle plant", is a herbaceous plant native to North America, parts of Eurasia, and has a rare introduction in Britain. It tends to grow in woodlands, meadows, and in disturbed areas as both a perennial and annual. Erect when young, this plant later becomes decumbent as it lies down, and branches regularly. It is not to be confused with similar plants in the same genus which are also often referred to as "yellow woodsorrel".
Oxalis bowiei, Bowie's wood-sorrel, red-flower woodsorrel, or Cape shamrock, is a plant from the genus Oxalis, which is native to what was Cape Province and KwaZulu-Natal in South Africa. It has also been naturalized in Australia.
Aedia leucomelas, the eastern alchymist, sweet potato leaf worm or sorcerer, is a moth of the family Noctuidae. It is found in large parts of the world, ranging from Europe all over Asia up to Japan and some African countries. The subspecies Aedia leucomelas acronyctoides is found in Australia.
Melanthera, squarestem, is a genus of flowering plants in the daisy family, Asteraceae, native to North and South America, as well as Africa, Asia and Oceania, including Hawaiʻi.
Pes-caprae is Latin for "goat's foot" and may refer to:
Oxalis glabra is a member of the wood-sorrel family, Oxalidaceae. It is only one of the 800 total species belonging to this family. The plant is commonly known as finger-leaf due to its trifoliate leaf structure. This trifoliate structure can be seen in variations throughout all members of the genus Oxalis. However, the particularly narrow leaflets of the glabra plant look more like fingers rather than a common clover. The plant is native to South Africa and can be found carpeting the ground of woodlands and bushlands.
Scutiger pes-caprae is a species of fungus in the family Albatrellaceae. It was first described officially as a species of Polyporus by Christian Hendrik Persoon in 1818. In recent decades, it was known most commonly as a species of Albatrellus until molecular research published by Canadian mycologist Serge Audet in 2010 revealed that it was more appropriate in an emended version of the genus Scutiger.
Puccinia oxalidis is a fungus species in the genus Puccinia. This species is a causal agent of rust on plants in the genus Oxalis, such as Oxalis articulata. The disease appears as yellow dots on the reverse of the leaves. The aecial stage can be found on Berberis repens.
Oxalis debilis, the large-flowered pink-sorrel or pink woodsorrel, is a perennial plant and herb in the family Oxalidaceae. Its original distribution is South America but has become a very cosmopolitan species, occurring in all continents except Antarctica. It can be found in both temperate and tropical areas.
Ipomoea imperati, the beach morning-glory, is a species of flowering plant in the family Convolvulaceae. Like Ipomoea pes-caprae, its seeds disperse by floating in seawater. It has been found on the sandy shores of every continent except Antarctica.
