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, Indian subcontinent, the Pacific Islands and the West Indies, where it has caused severe ecological damage in some cases. The plant has a number of common names including golden pothos, Ceylon creeper, hunter's robe, ivy arum, silver vine, Solomon Islands ivy, and taro vine. It

The Maloideae C.Weber was the apple subfamily, a grouping used by some taxonomists within the rose family, Rosaceae. Recent molecular phylogenetic evidence has shown that the traditional Spiraeoideae and Amygdaloideae form part of the same clade as the traditional Maloideae, and the correct name for this group is Amygdaloideae. Earlier circumscriptions of Maloideae are more-or-less equivalent to subtribe Malinae or to tribe Maleae. The group includes a number of plants bearing commercially important fruits, such as apples and pears, while others are cultivated as ornamentals. In its

Lycopodiella inundata is a species of club moss known by the common names inundated club moss, marsh clubmoss and northern bog club moss. It has a circumpolar and circumboreal distribution, occurring throughout the northern Northern Hemisphere from the Arctic to montane temperate regions in Eurasia and North America. It grows in wet habitat, such as bogs, ponds, moist spots on the tundra, and long-standing borrow pits.

Dolomiaea costus, formerly known as Saussurea costus, commonly known as costus, Indian costus, kuth, or putchuk, is a species of thistle in the genus Dolomiaea native to South Asia and China. Rishi (Hindu) mystics of Kashmir especially ate this plant. Essential oils extracted from the root have been used in traditional medicine and in perfumes since ancient times. Costus is the root of this plant. The root of the plant is the key part used for medicinal or homeopathic purposes. The root is also called by its Latin name radix aucklandiae (root of aucklandia). It has a large number of names in

Lycopodiella is a genus in the clubmoss family Lycopodiaceae. The genus members are commonly called bog clubmosses, describing their wetland habitat. In the past, the genus was often incorporated within the related genus Lycopodium, but was segregated in 1964. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), Lycopodiella is placed in the subfamily Lycopodielloideae, along with three other genera. In this circumscription, the genus has about 15 species. Other sources use a wider circumscription, in which the genus is equivalent to the Lycopodielloideae of PPG I, in which

Pinus chiapensis is a pine tree species in the family Pinaceae, and is commonly known as Chiapas pine, in Spanish as pino blanco, pinabete, or ocote. Chiapas pine was formerly considered to be a variant of Pinus strobus, but is now understood to be a separate species.

Petrorhagia nanteuilii is a species of flowering plant in the family Caryophyllaceae. Common names include childing pink, productive carnation, proliferous pink and wild carnation. P. nanteuilii in the British Isles was formerly not reliably separated from P. prolifera but now the two are recorded as separate species. Because of this the commonly used name proliferous pink is probably not correct for this taxon. It is an annual that grows to 50 cm tall. Leaves are linear, opposite and stem clasping. Small pink flowers are produced in small ovoid heads, with usually only one flower visible at

Aloe ballii is a species of plant in the family Asphodelaceae, subfamily Asphodeloideae. It is found in Mozambique and Zimbabwe.

Ludwigia peploides is a species of flowering plant in the evening primrose family known by the common names floating primrose-willow and creeping water primrose. It is native to Australia, North America, and South America, but it can be found on many continents and spreads easily to become naturalized. It is well known as a troublesome aquatic noxious weed that invades water ecosystems and can clog waterways. This is perennial herb which grows in moist to wet to flooded areas. The stem can creep over 2 meters long, sometimes branching. It spreads to form mats on the mud, or floats ascending
