Arundina graminifolia is a species of orchid and the sole accepted species of the genus Arundina. This tropical Asiatic genus extends from Myanmar, India, Sri Lanka, Nepal, Thailand, Vietnam, the Ryukyu Islands, Malaysia, Singapore, China to Indonesia, the Philippines and New Guinea. It has become naturalized in Réunion, Fiji, French Polynesia, Micronesia, the West Indies, Costa Rica, Panama, Belize, and Hawaii. [2] [5] It is also called bamboo orchid. [6]
Arundina graminifolia is a terrestrial, perennial orchid with reedy stems, forming into large clumps growing to a height between 70 cm and 2 m.
The plaited linear leaves are oblong lanceolate, with a length of 9 to 19 cm and a width of 0.8 to 1.5 cm. The apex is acuminate. There are amplexicaul (clasping the stem) sheathing stipules.
This orchid blooms in summer and autumn, showing rather open clusters of showy terminal flowers, ten at the most. They bloom in succession on the terminal racemes,which are 7 to 16 cm long. These flowers, 5–8 cm in diameter, are a rosy lilac and white disc with a purple lip. The bracts are broadly triangular and surround the main stalk of the flower cluster. The occasional fertilized seed pods contain minute powdery seeds, and small plants often develop near the cane ends after flowering, which likely aid in propagation if allowed to reach the soil.
At one point in time only 200 of the plants were recorded growing naturally in Singapore, rendering the species close to extinction. This was due to the destruction of its natural habitat, namely the rainforests and mangrove forests. However, through replanting efforts by NParks, the species is now listed as a "common" cultivated plant. [7] In Malaysia A. graminifolia is commonly called tapah and can be found in secondary forests or at forest fringes. It is very common in road cuts and other disturbed areas in full sun in Sarawak, where it is often the most common flowering plant seen along the roadsides.
It is invasive on the big island of Hawaii and common there in mid-mountain areas.
Two varieties are currently recognized (May 2014): [2]
Epipremnum aureum is a species in the arum family Araceae, native to Mo'orea in the Society Islands of French Polynesia. The species is a popular houseplant in temperate regions but has also become naturalised in tropical and sub-tropical forests worldwide, including northern South Africa, Australia, Southeast Asia, South Asia, the Pacific Islands and the West Indies, where it has caused severe ecological damage in some cases.
Delonix regia is a species of flowering plant in the bean family Fabaceae, subfamily Caesalpinioideae native to Madagascar. It is noted for its fern-like leaves and flamboyant display of orange-red flowers over summer. In many tropical parts of the world it is grown as an ornamental tree and in English it is given the name royal poinciana, flamboyant, phoenix flower, flame of the forest, phượng vĩ or flame tree.
Plumeria, also known as frangipani, is a genus of flowering plants in the subfamily Rauvolfioideae, of the family Apocynaceae. Most species are deciduous shrubs or small trees. The species are native to the Neotropical realm, but are often grown as cosmopolitan ornamentals in tropical regions, especially in Hawaii, as well as hot desert climates in the Arabian Peninsula with proper irrigation.

Bletilla, common name urn orchid, is a temperate, terrestrial genus of orchids containing five currently recognized species distributed through China, Japan, Taiwan, south to Vietnam, Thailand and Myanmar. The name is actually a diminutive of Bletia because of the resemblance between the two genera even though Bletia is a New World genus. The genera JimensiaRaf. and PolytomaLour. ex Gomes are generally included into Bletilla. This genus is abbreviated Ble in trade journals.
Corypha umbraculifera, the talipot palm, is a species of palm native to eastern and southern India and Sri Lanka. It is also grown in Cambodia, Myanmar, Thailand, Mauritius and the Andaman Islands. It is one of the five accepted species in the genus Corypha. It is a flowering plant with the largest inflorescence in the world. It lives up to 60 years before bearing flowers and fruits. It dies shortly after.
