Macarthur palm

 
 

Macarthur palm is native to Indonesia, New Guinea, and northern Australia. It reaches a height of 25 feet, with several ringed smooth trunks up to 3 inches in diameter. The leaves are up to 6 feet long and are composed of two rows of leaflets, many of which bifurcate apically. Inflorescences arise below the lowest leaf are about 2 feet long. Ripe fruits are red and up to half an inch long. It flowers and produces fruits throughout the year. The generic name means folded seed. The species name honors Australian horticulturist Wiliam Macarthur (1800-1882).

The photographed palm is one of several planted between the Chardón Building and the Student Union. There are several other specimens in the campus; for example, in front of the Student Union, in front of the Monzón Building, in front and west of the de Diego Building, behind the Sánchez Hidalgo Building, and in the patio of the Stefani Building.
