Amaranthus, collectively known as amaranth, is a cosmopolitan genus of annual or short-lived perennial plants.
 Some amaranth species are cultivated as leaf vegetables, pseudocereals, and ornamental plants. Most of the "Amaranthus" species are summer annual weeds and are commonly referred to as pigweed.
 Catkin-like cymes of densely packed flowers grow in summer or autumn.
 Approximately 60 species are recognized, with inflorescences and foliage ranging from purple, through red and green to gold.
 Members of this genus share many characteristics and uses with members of the closely related genus "Celosia".
Diocirea is a genus of flowering plants in the figwort family, Scrophulariaceae.
 The genus is endemic to a small area in the south-west of Western Australia and is intermediate in character between "Eremophila" and "Myoporum".
 There are four members of the genus, all of which are small shrubs with stems and leaves which produce a resin making the plants appear bluish-green.
 Neither the genus, nor any of the species had been described before 2007 although a few specimens had been collected as "Eremophila elachantha".
 Despite their limited distribution, they often occur in populations of several thousand individual plants, forming a dense ground cover.
Asparagus is a genus of flowering plants in the family Asparagaceae, subfamily Asparagoideae.
 It comprises up to 300 species.
 Most are evergreen long-lived perennial plants growing from the understory as lianas, bushes or climbing plants.
 The best-known species is the edible "Asparagus officinalis", commonly referred to as just "asparagus".
 Some other members of the genus, such as "Asparagus densiflorus", are grown as ornamental plants.
Haberlea is a monotypic genus of flowering plants in the family Gesneriaceae.
 The only member of this genus, Haberlea rhodopensis, is endemic to several mountains in Bulgaria, especially the Rhodope mountains, and small part of northern Greece.
 Common names include Orpheus flower and resurrection plant because of the remarkable ability of "Haberlea" to survive very long periods of desiccation.
Cicuta, commonly known as water hemlock, is a small genus of four species of highly poisonous plants in the family Apiaceae.
 They are perennial herbaceous plants which grow up to 2.5 m tall, having distinctive small green or white flowers arranged in an umbrella shape (umbel).
 Plants in this genus may also be referred to as cowbane or poison parsnip.
 "Cicuta" is native to temperate regions of the Northern Hemisphere, mainly North America and Europe, typically growing in wet meadows, along streambanks and other wet and marshy areas.
 These plants bear a close resemblance to other members in the family Apiaceae and may be confused with a number of other edible and poisonous plants.
 The common name hemlock may also be confused with poison hemlock ("Conium maculatum").
Melon necrotic spot virus (MNSV) is a virus that belongs to the "Carmovirus" genus of viruses in the "Tombusviridae" family.
 It has been observed in several countries of the Americas, Africa, Asia, and Europe.
 It is considered to be an endemic virus in greenhouses and field productions of Cucurbitaceae crops, including melon ("Cucumis melo"), cucumber ("Cucumbis sativus"), and watermelon ("Citrullus lanatus").
 MNSV is mainly spread through infected soil, seedlings, insects, and by the root-inhabiting fungus vector "Olpidium bornovanus".
 Symptoms vary between Curbitaceae crops, but generally consist of chlorosis, brown necrotic lesions, leaf wilt, fruit decay, and plant death.
 Management of the disease consists of preventing infection by rotating fields and crops, steam sterilization, and disposal of infected plants.
 Also, treated seeds with heat or chemicals are efficient in preventing infection.
 MNSV is important in melon plants as it causes vast economical damage worldwide reducing significant yields.
Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge, in the spurge family (Euphorbiaceae).
 "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae (in deference to the type genus), not just to members of the genus.
 Some euphorbias are commercially widely available, such as poinsettias at Christmas.
 Some are commonly cultivated as ornamentals, or collected and highly valued for the aesthetic appearance of their unique floral structures, such as the crown of thorns plant.
 Euphorbias from the deserts of Southern Africa and Madagascar have evolved physical characteristics and forms similar to cacti of North and South America, so they (along with various other kinds of plants) are often incorrectly referred to as "cacti".
 Some are used as ornamentals in landscaping, because of beautiful or striking overall forms, and drought and heat tolerance.
Cucumis is a genus of twining, tendril-bearing plants in the Cucurbitaceae family which includes the cucumber ("Cucumis sativus"), muskmelons ("Cucumis melo", including cantaloupe and honeydew), the horned melon ("Cucumis metuliferus"), and the West Indian gherkin ("Cucumis anguria").
Many plants are poisonous to equines; the species vary depending on location, climate, and grazing conditions.
 In many cases, entire genera are poisonous to equines and include many species spread over several continents.
 Plants can cause reactions ranging from laminitis (found in horses bedded on shavings from black walnut trees), anemia, kidney disease and kidney failure (from eating the wilted leaves of red maples), to cyanide poisoning (from the ingestion of plant matter from members of the "Prunus" genus) and other symptoms.
 Members of the "Prunus" genus have also been theorized to be at fault for mare reproductive loss syndrome.
 Some plants, including yews, are deadly and extremely fast-acting.
 Several plants, including nightshade, become more toxic as they wilt and die, posing a danger to horses eating dried hay or plant matter blown into their pastures.
Centaurea ( ) is a genus of between 350 and 600 species of herbaceous thistle-like flowering plants in the family Asteraceae.
 Members of the genus are found only north of the equator, mostly in the Eastern Hemisphere; the Middle East and surrounding regions are particularly species-rich.
 Common names for this genus are centaury, centory, starthistles, knapweeds, centaureas and the more ambiguous "bluets"; a vernacular name used for these plants in parts of England is "loggerheads" (common knapweed).
 The "Plectocephalus" group – possibly a distinct genus – is known as basketflowers.
 "Cornflowers" is used for a few species, but that term more often specifically means "C. cyanus" (sometimes also called "basket flower").
 The common name "centaury" is sometimes used, although this also refers to the unrelated plant genus "Centaurium".
