Pandanus cookii

Pandanus cookii, commonly known as Cook's pandan, Cook's screwpine or simply screwpine, is a tree in the family Pandanaceae which is endemic to coastal and sub-coastal parts of tropical Queensland, Australia. It grows to around 10 m in height with an open habit, long narrow leaves up to 180 by and prop roots up to around 30 cm long.

Taxonomy
This species was first described by the Italian botanist Ugolino Martelli in a paper titled Le specie e varieta nuove di "Pandanus" menzionate nella enumerazione delle Pandanaceae. It was published in the journal Webbia in 1914. Martelli's description was based on material collected in 1904 by a Mr. Dempsey near Cooktown.

Etymology
The species is named after the English explorer Captain James Cook, who in 1770 was forced to spend some time in an inlet now known as the Endeavour River to repair his ship. The town of Cooktown was established on the banks of that river in 1873, and it was in this area that the type specimen was collected and provided to Martinelli.
