Praecereus is genus of cactus. It is sometimes included in the genus Cereus .
Plants have a bushy to tree-like species that are sometimes stretched out, mostly freely branched and reach a height of up to 6 meters. The slender, columnar to hanging shoots have 7 or more ribs with protruding, round and gray areoles from which needle-like or umbilical thorns arise.
The robust, funnel- to bell-shaped flowers are white to yellowish green and open during the day. Its strong flower cup and flower tube are thick-walled, fleshy and often curved.
The fleshy, short, ovoid fruits that split open lengthwise are red with a persistent flower residue and contain white flesh. The black, bumpy seeds are oblong and ovoid and somewhat compressed at the sides.

In botany, a drupe is an indehiscent fruit in which an outer fleshy part surrounds a single shell of hardened endocarp with a seed (kernel) inside. These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries.
Amorphophallus is a large genus of some 200 tropical and subtropical tuberous herbaceous plants from the Arum family (Araceae), native to Asia, Africa, Australia and various oceanic islands. A few species are edible as "famine foods" after careful preparation to remove irritating chemicals. The genus includes the Titan arum of Indonesia, which has the largest inflorescence of any plant in the genus, and is also known as the 'corpse flower' for the pungent odour it produces during its flowering period, which can take up through seven years of growth before it occurs.
Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae. "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae, not just to members of the genus.
Batis is a genus of two species of flowering plants, the only genus in the family Bataceae. They are halophytic plants, native to the coastal salt marshes of warm temperate and tropical America and tropical Australasia.
Matucana is a genus of cacti, containing approximately 20 species of mostly globular plants. The genus is only known from Peru, mostly along the Marañón River.
Clusia is the type genus of the plant family Clusiaceae. Comprising 300-400 species, it is native to the tropics of the Americas. The genus is named by Carl Linnaeus in honor of the botanist Carolus Clusius.
Stetsonia coryne, the toothpick cactus, is the sole species in the cactus genus Stetsonia. The plant is native to the deserts and dry forest of Argentina, Bolivia and Paraguay. Stetsonia coryne grows to a height of 15 to 25 ft tall. It has white flowers. The genus was named to honor Francis Lynde Stetson, a New York attorney and plant lover.
Cephalocereus is a genus of slow-growing, columnar-shaped, blue-green cacti. The genus is native to Mexico.
Polaskia is a genus of tree-like cacti reaching 4–5 m high, comprising 2 species. Both present primitive characteristics, but Polaskia chichipe is nearer to Myrtillocactus while Polaskia chende is nearer to Stenocereus. The genus is found in the Mexican states of Puebla and Oaxaca.
Caladenia, commonly known as spider orchids, is a genus of 350 species of plants in the orchid family, Orchidaceae. Spider orchids are terrestrial herbs with a single hairy leaf and a hairy stem. The labellum is fringed or toothed in most species and there are small projections called calli on the labellum. The flowers have adaptations to attract particular species of insects for pollination. The genus is divided into three groups on the basis of flower shape, broadly, spider orchids, zebra orchids and cowslip orchids, although other common names are often used. Although they occur in other countries, most are Australian and 136 species occur in Western Australia, making it the most species-rich orchid genus in that state.
In botany, a berry is a fleshy fruit without a stone (pit) produced from a single flower containing one ovary. Berries so defined include grapes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines) and bananas, but exclude certain fruits that meet the culinary definition of berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible "pericarp". Berries may be formed from one or more carpels from the same flower. The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as peppers, with air rather than pulp around their seeds.
Baeckea is a genus of flowering plants in the myrtle family, Myrtaceae, all but one endemic to Australia. Plants in the genus Baeckea are shrubs or small trees with leaves arranged in opposite pairs, white to deep pink flowers with five sepals and five petals, and five to fifteen stamens that are shorter than the petals.
Thalictrum thalictroides, synonym Anemonella thalictroides, the rue-anemone, is a herbaceous perennial plant native to woodland in eastern North America. It has white or pink flowers surrounded by a whorl of leaflets, and it blooms in spring.
The genus Platanthera belongs to the subfamily Orchidoideae of the family Orchidaceae, and comprises about 150 species of orchids. The members of this genus, known as the butterfly orchids or fringed orchids, were previously included in the genus Orchis, which is a close relative. They are distributed throughout the temperate regions of the Northern Hemisphere. They are terrestrial and have tubercules.
Sedum album, the white stonecrop, is a flowering plant of the genus Sedum in the family Crassulaceae. It is found in the northern temperate regions of the world, often growing in crevices or free-draining rocky soil. As a long-day plant it grows vegetatively for most of the year and flowers in summer.
Codonanthe is a genus of mainly epiphytic plants in the family Gesneriaceae, endemic to the Atlantic Forest of Brazil. The botanical name comes from the Ancient Greek for 'bellflower'. They have white or pale pink flowers and somewhat fleshy leaves. In 2013, the genus was reduced in size when more than half of the species were transferred to Codonanthopsis. They can be grown as houseplants, particularly in hanging baskets. Artificial crosses with Nematanthus hybrids have produced the hybrid genus × Codonatanthus.
Cereus ( "serious") is a genus of cacti including around 33 species of large columnar cacti from South America. The name is derived from Greek (κηρός) and Latin words meaning "wax", "torch" or "candle". Cereus was one of the first cactus genera to be described; the circumscription varies depending on the authority. The term "cereus" is also sometimes used for a ceroid cactus, any cactus with a very elongated body, including columnar growth cacti and epiphytic cacti.
Viridivia is a monotypic genus of flowering plants belonging to the family Passifloraceae. It only contain one known species, 'Viridivia suberosa'J.H.Hemsl. & Verdc. It is also in the subfamily Passifloroideae and Tribe Paropsieae.
