Pandanales, the pandans or screw-pines, is an order of flowering plants placed in the monocot clade in the Angiosperm Phylogeny Group and Angiosperm Phylogeny Web systems. Within the monocots Pandanales are grouped in the lilioid monocots where they are in a sister group relationship with the Dioscoreales. Historically the order has consisted of a number of different families in different systems but modern classification of the order is based primarily on molecular phylogenetics despite diverse morphology which previously placed many of the families in other groupings based on apparent similarity. Members of the order have a subtropical distribution and includes trees, shrubs, and vines as well as herbaceous plants. The order consists of 5 families, 36 genera and about 1,610 species.
Pandanus is a genus of monocots with some 750 accepted species. They are palm-like, dioecious trees and shrubs native to the Old World tropics and subtropics. The greatest number of species are found in Madagascar and Malaysia. Common names include pandan, screw palm, and screw pine. They are classified in the order Pandanales, family Pandanaceae.

Pandanaceae is a family of flowering plants native to the tropics and subtropics of the Old World, from West Africa through the Pacific. It contains 982 known species in five genera, of which the type genus, Pandanus, is the most important, with species like Pandanus amaryllifolius and karuka being important sources of food. It is an ancient family dating from the early to mid-Cretaceous. This is a family that is not-well studied.
Pandanus amaryllifolius is a tropical plant in the Pandanus (screwpine) genus, which is commonly known as pandan. It has fragrant leaves which are used widely for flavouring in the cuisines of Southeast Asia and South Asia.
Pandanus utilis, the common screwpine is, despite its name, a monocot and not a pine. It is native to Madagascar and naturalised in Mauritius and the Seychelles.
Pandanus pyramidalis is a species of plant in the family Pandanaceae, endemic to Mauritius.
Ugolino Martelli (1860–1934) was an Italian botanist, biologist, and mycologist. Martelli is known for his studies of and contributions to the systematics of the tropical genus Pandanus and his taxonomic definition of the flora of Sardinia. He also specialized in studies of the flora of Tuscany and Malaysia.
Pandanus livingstonianus Rendle is one of some 752 palaeotropical species of dioecious tree in the genus Pandanus, popularly known as Screw pines, and occurs from Angola eastwards across tropical Africa and down the east coast of Southern Africa.
Pandanus odorifer is an aromatic monocot species of plant in the family Pandanaceae, native to Polynesia, Australia, South Asia, and the Philippines, and is also found wild in southern India and Burma. It is commonly known as fragrant screw-pine.
Pandanus vandermeeschii is a species of plant in the family Pandanaceae. It is endemic to the coastal areas of Mauritius.
Pandanus iceryi ("Vacoas") is a species of plant in the family Pandanaceae. It is endemic to Mauritius.
The karuka is a species of tree in the family Pandanaceae and an important regional food crop in New Guinea. The nuts are more nutritious than coconuts, and are so popular that villagers in the highlands will move their entire households closer to trees for the harvest season.

Pandanus aridus is a species of shrub or small tree in the family Pandanaceae. It is native and endemic to Madagascar, found in fragmented locations in the southern third of the country. Pandanus aridus H. St. John is the accepted name, with a synonym of Pandanus toliarensis Huynh.
Pandanus connatus is a species of plant in the family Pandanaceae native to northern Madagascar. Pandanus acuminatus Hort. ex Wendl. is considered a synonym for the accepted name P. connatus.
Pandanus subglobosus is a dioecious tropical shrub in the screwpine genus. It is endemic to Madagascar. The specific epithet, "subglobosus", refers to the nearly-round fruits. The accepted name for this species is now Pandanus oligocarpus.
Sijfert Hendrik Koorders was a Dutch botanist, who worked primarily on the flora of Java.
