Pandanus's Flower -Screwpine

Often called pandanus palms, these plants are not closely related to palm trees. The botanical family Pandanaceae consists of three genera, namely Sararanga (two species), Freycinetia ^[4] The species vary in size from small shrubs less than 1 metre (3.3 ft) tall, to medium-sized trees 20 metres (66 ft) tall, typically with a broad canopy, heavy fruit, and moderate growth rate.^[5] The trunk is stout, wide-branching, and ringed with many leaf scars. They commonly have many thick prop roots near the base, which provide support as the tree grows top-heavy with leaves, fruit, and branches. The leaves are strap-shaped, varying between species from 30 centimetres (12 in) to 2 metres (6.6 ft) or more long, and from 1.5 centimetres (0.59 in) up to 10 centimetres (3.9 in) broad.

They are dioecious, with male and female flowers produced on different plants. The flowers of the male tree are 2–3 centimetres (0.79–1.2 in) long and fragrant, surrounded by narrow, white bracts. The female tree produces flowers with round fruits that are also bract-surrounded. The fruits are globose, 10–20 centimetres (3.9–7.9 in) in diameter, and have many prism-like sections, resembling the fruit of the pineapple. Typically, the fruit changes from green to bright orange or red as it matures. The fruit of some species are edible. Pandanus fruit are eaten by animals including bats, rats, crabs, elephants and monitor lizards, but the vast majority of species are dispersed primarily by water.^[6]
