Ptychosperma macarthurii is a species of palm in the Arecaceae family. It is found only in isolated occurrences in the Northern Territory and Queensland in Australia, and also in New Guinea.[1] The species is commonly used as an interior landscaping plant.[2]

Ptychosperma macarthurii was named for Sir William Macarthur (1800–1882), who was one of the most active and influential horticulturists in Australia in the mid-to-late 19th century.

A population of this species near Darwin was previously named Ptychosperma bleeseri and thought to be lost due to habitat loss.[3]

Physical description[edit]

The leaves are pinnately compound and can have between 15 and 40 pinnae on each side of the rachis.[4] As an adult, its stems can grow up to 30 feet tall,[4] although most adults are typically 10 to 15 feet tall.[5]
