Carnivorous plant that captures prey by quickly closing its leaves into a jaw-like trap
This article is about the plant. For other uses, see Venus Flytrap (disambiguation).
The Venus flytrap (Dionaea muscipula) is a carnivorous plant native to subtropical wetlands on the East Coast of the United States in North Carolina and South Carolina. It catches its prey—chiefly insects and arachnids—with a trapping structure formed by the terminal portion of each of the plant's leaves, which is triggered by tiny hairs (called "trigger hairs" or "sensitive hairs") on their inner surfaces.
Nepenthes mirabilis
Wide-ranging species of tropical pitcher plant
"Nepenthes phyllamphora" redirects here. For other uses, see Nepenthes phyllamphora (disambiguation).
Nepenthes mirabilis (/nɪˈpɛnθiːz mɪˈræbɪlɪs/; from Latin mirabilis "wonderful"), or the common swamp pitcher-plant and tropical pitcher plant, is a carnivorous plant species. By far the most widespread of all Nepenthes, its range covers continental Southeast Asia and all major islands of the Malay Archipelago (minus the Lesser Sunda Islands and northern Philippines), stretching from China in the north to Australia in the south. The species exhibits great variability throughout its range. One of the more notable varieties, N. mirabilis var. echinostoma, is endemic to Brunei and Sarawak and possesses an extremely wide peristome.
Quick Facts Conservation status, Scientific classification ...
The conservation status of N. mirabilis is listed as Least Concern on the IUCN Red List. In Hong Kong, it is a protected species under Forestry Regulations Cap. 96A.
According to Matthew Jebb and Martin Cheek, the pitchers of N. mirabilis are used as toy phallocrypts in New Guinea.
Nepenthes gracilis
Species of pitcher plant from Southeast Asia
Nepenthes gracilis (/nɪˈpɛnθiːz ˈɡræsɪlɪs/; from Latin: gracilis "slender"), or the slender pitcher-plant, is a common lowland pitcher plant that is widespread in the Sunda region. It has been recorded from Borneo, Cambodia, Peninsular Malaysia, Singapore, Sulawesi, Sumatra, and Thailand. The species has a wide altitudinal distribution of 0 to 1100 m (and perhaps even 1700 m) above sea level, although most populations are found below 100 m and plants are rare above 1000 m. Despite being a widespread plant, natural hybrids between N. gracilis and other species are quite rare.
Quick Facts Conservation status, Scientific classification ...
Nepenthes gracilis was formally described by Pieter Willem Korthals in his 1839 monograph, "Over het geslacht Nepenthes".
Nepenthes abgracilis from the Philippines is named for its superficial similarity to this species.
Calliandra surinamensis is a low branching evergreen tropical shrub that is named after Suriname, a country in northern South America. The plant usually has complexly branched multiple trunks and grows to a height of about 5 metres, although many sources suggest that it only attains a height of 3 metres
Plumeria rubra
Species of tree
For the Hindu temple element, see Sthala Vriksha.
Plumeria rubra is a deciduous plant species belonging to the genus Plumeria. Originally native to Mexico, Central America, Colombia and Venezuela, it has been widely cultivated in subtropical and tropical climates worldwide and is a popular garden and park plant, as well as being used in temples and cemeteries. It grows as a spreading tree to 7–8 m (23–26 ft) high and wide, and is flushed with fragrant flowers of shades of pink, white and yellow over the summer and autumn.
Quick Facts Scientific classification, Binomial name ...
Plumeria rubra was one of the many species first described by Carl Linnaeus, and appeared in the 1753 edition of Species Plantarum. Its specific epithet is derived from the Latin ruber "red". The epithets acuminata, acutifolia, and lutea are seen, but these are invalid. Its common names include frangipani, red paucipan, red-jasmine, red frangipani, common frangipani, temple tree, or simply plumeria.
Alocasia
genus of flowering plant
Alocasia is a genus of broad-leaved, rhizomatous, or tuberous perennial flowering plants from the family Araceae. There are 97 accepted species native to tropical and subtropical Asia and Eastern Australia. Around the world, many growers widely cultivate a range of hybrids and cultivars.
Quick Facts Scientific classification, Type species ...
Description
The large, cordate, or sagittate leaves grow to a length of 20 to 90 cm (8 to 35 inches) on long petioles. Their araceous flowers grow at the end of a short stalk, but are not conspicuous; often hidden behind the leaf petioles.
The corms of some species can be processed to make them edible, however, the raw plants contain raphid or raphide crystals of calcium oxalate along with other irritants (possibly including proteases) that can numb and swell the tongue and pharynx. This can cause difficulty breathing and sharp pain in the throat. Lower parts of the plant contain the highest concentrations of the poison.
Prolonged boiling before serving or processing may reduce risk of adverse reactions. Additionally, acidic fruit such as tamarind may dissolve the raphides altogether. It's important to note, however, that this species varies in toxicity, and can still be dangerous to ingest, even after taking precautions.
Cultivation
Alocasia are tropical plants that are increasingly becoming popular as houseplants. The hybrid A. × amazonica has gained the Royal Horticultural Society's Award of Garden Merit. They are typically grown as pot plants, but a better way is to grow the plants permanently in the controlled conditions of a greenhouse. They do not do well in the dark and need good lighting if inside the house. They should be cared for as any other tropical plant with weekly cleaning of the leaves, frequent fertilization and medium to high humidity.
They rarely survive cold winters or the dryness of artificial heating, but an attempt to slowly acclimatize plants from the summer garden to the house can help. Once inside, the watering period must be reduced and the plants should be protected from spider mites or red spider attack.
Species
The following are 80 of the 97 accepted species classified under Alocasia along with their common names (where available) and distribution ranges:
Canna 'Bengal Tiger'

Dracaena fragrans
Species of flowering plant
Dracaena fragrans (cornstalk dracaena), is a flowering plant species that is native throughout tropical Africa, from Sudan south to Mozambique, west to Côte d'Ivoire and southwest to Angola, growing in upland regions at 600–2,250 m (1,970–7,380 ft) altitude. It is also known as striped dracaena, compact dracaena, and corn plant.
The NASA Clean Air Study was a project led by the National Aeronautics and Space Administration (NASA) in association with the Associated Landscape Contractors of America (ALCA) to research ways to clean the air in space stations. Its results suggested that, in addition to absorbing carbon dioxide and releasing oxygen through photosynthesis, certain common indoor plants may also provide a natural way of removing volatile organic pollutants (benzene, formaldehyde, and trichloroethylene were tested).
These results failed to replicate in future studies, which stated that "future research is needed to fully understand indoor VOC removal by plants."
List of plants studied
The following plants were tested during the initial 1989 study:
English ivy (Hedera helix)
Peace lily (Spathiphyllum 'Mauna Loa')
Chinese evergreen (Aglaonema modestum)
Bamboo palm (Chamaedorea seifrizii)
Red-edged dracaena, marginata (Dracaena marginata)
Cornstalk dracaena, mass cane/corn cane (Dracaena fragrans 'Massangeana')
Weeping fig (Ficus benjamina)
Barberton daisy, gerbera daisy (Gerbera jamesonii)
Florist's chrysanthemum, pot mum (Chrysanthemum morifolium)
Janet Craig (Dracaena deremensis "Janet Craig")
Warneckei (Dracaena deremensis "Warneckei")

Additional research
Since the release of the initial 1989 study, titled A study of interior landscape plants for indoor air pollution abatement: An Interim Report, further research has been done including a 1993 paper and 1996 book by B. C. Wolverton, the primary researcher on the original NASA study, that listed additional plants and focused on the removal of specific chemicals. A different study in 2004 has also shown that the micro-organisms in the soil of a potted plant remove benzene from the air, and that some plant species themselves also contribute to removing benzene.

Cyperus papyrus, papyrus, papyrus sedge, paper reed, Indian matting plant or Nile grass, is a species of aquatic flowering plant belonging to the sedge family Cyperaceae. It is a tender herbaceous perennial, native to Africa, and forms tall stands of reed-like swamp vegetation in shallow water.
Papyrus sedge (and its close relatives) has a very long history of use by humans, notably by the Ancient Egyptians—it is the source of papyrus paper, one of the first types of paper ever made. Parts of the plant can be eaten, and the highly buoyant stems can be made into boats. It is now often cultivated as an ornamental plant.
In nature, it grows in full sun, in flooded swamps, and on lake margins throughout Africa, Madagascar, and the Mediterranean countries.
Calathea
Genus of plants
Calathea is a genus of flowering plants belonging to the family Marantaceae. They are commonly called calatheas or (like their relatives) prayer plants. About 200 species formerly assigned to Calathea are now in the genus Goeppertia. Calathea currently contains around 60 species. Native to the tropical Americas, many of the species are popular as pot plants due to their decorative leaves and, in some species, colorful inflorescences. The young leaves and bracts can retain pools of water called phytotelmata, that provide habitat for many invertebrates.
