Ceroxylon quindiuense, is a palm native to the humid montane forests of the Andes in Colombia and northern Peru.[3]

Description[edit]

View of Cocora Valley (Colombia) with Ceroxylon quindiuense palms.

This palm species can grow to a height of 45 m (148 ft)—or rarely, even as high as 60 m (200 ft).[3] It is the tallest recorded monocot in the world.[4] The trunk is cylindrical, smooth, light colored, covered with wax; leaf scars forming dark rings around the trunk.[3] The leaves are dark green and grayish, 185–540 cm long, with a petiole up to 80 cm long.[3] Fruits are globose and orange-red when ripe, 1.6–2 cm in diameter.[3]

Ecology[edit]

It grows in large and dense populations along the central and eastern Andes of Colombia (rarely in the western Colombian Andes), with a disjunct distribution in the Andes of northern Peru.[3] The elevational range of this species is between 2,000 and 3,100 m (6,600 and 10,200 ft) above sea level.[3] It achieves a minimum reproductive age at 80 years.[5] Wax palms provide habitats for many unique life forms, including endangered species such as the yellow-eared parrot (Ognorhynchus icterotis).

Vernacular names[edit]

Palma de cera, palma de ramo (both names in Colombia).[3]

Conservation[edit]

Populations of Ceroxylon quindiuense are threatened by habitat disturbance, overharvesting and diseases.[5] The fruit was used as feed for cattle and pigs. The leaves were extensively used in the Catholic celebrations of Palm Sunday;[6] such leaves coming from young individuals which were damaged to death.[5] That activity has been reduced severely in recent years due to law enforcement and widespread campaign.[3] Felling of Ceroxylon quindiuense palms to obtain wax from the trunk also is an activity still going on in Colombia and Peru.[3] The palm is recognized as the national tree of Colombia, and since the implementation of Law 61 of 1985, it is legally a protected species in that country.[5][7]

Cultivation and uses[edit]

The wax of the trunk was used to make candles, especially in the 19th century.[3] The outer part of the stem of the palm has been used locally for building houses, and was used to build water supply systems for poor farmers.[3][5] It is cultivated as an ornamental plant in Colombia and USA.[3][5]
