Andes mountain range, western coast of South America.

Due to the palm’s slow growth, and agricultural land clearing within the tree’s natural range, it has become an endangered species in Ecuador.  The government now runs a campaign telling farmers to leave any wax palms found on their properties alone; not only are the palms rare, they are the preferred habitat for two species of endemic parrots (the El Oro Parikeet and the Loja Green Parrot) which are rapidly going extinct along with the trees.

Grows from the South of Colombia (Central Cordilllera, western slope in Cauca and Eastern slopes of the Andes in Putumayo) to the south-east of Ecuador, in moist montane forest or kept on pastures, at (1800-)2000-3000 m, usually above 2500 m. It is commonly found forming stands of hundreds of individuals. It is also cultivated as ornamental in Ecuador. (Maria Jose Sanin and Gloria Galeano. 2011)/Palmweb.

Ceroxylon ventricosum is characterized by its massive, robust and white stem, by its leaves twisted 90° on distal portion thereby holding the pinnae in a vertical position, the pinnae pendulous and arranged in hardly discernible groups toward the middle of the leaves, staminate flowers with 9-11 stamens and smooth fruits. The best way to distiguish it from C. quindiuense is in its grouped pinnae spreading in various planes, whereas, C. quindiuense has regularly arranged, pendulous (in one plane) pinnae.

Habitat and Distribution

Ceroxylon ventricosum is found in Andes mountain range, western coast of South America.
Ventura Landmark.
In Ecuador, this is the highest-altitude naturally occurring palm tree, appearing in the wild, well above 3,500 meters in paramo forests, and distributed down to about 1,800 m, especially in the province of Loja. Wax palms are so named for their single, waxy trunk. Due to the palm’s slow growth, and agricultural land clearing within the tree’s natural range, it has become an endangered species in Ecuador. The government now runs a campaign telling farmers to leave any wax palms found on their properties alone; not only are the palms rare, they are the preferred habitat for two species of endemic parrots (the El Oro Parikeet and the Loja Green Parrot) which are rapidly going extinct along with the trees.

Grows from the South of Colombia (Central Cordilllera, western slope in Cauca and Eastern slopes of the Andes in Putumayo) to the south-east of Ecuador, in moist montane forest or kept on pastures, at (1800-)2000-3000 m, usually above 2500 m. It is commonly found forming stands of hundreds of individuals. It is also cultivated as ornamental in Ecuador. (Maria Jose Sanin and Gloria Galeano. 2011)/Palmweb.

Description

Trunk type: Solitary, with a glossy crownshaft, the trunk exhibits a powdery white residue, much akin to baby powder, trunk has white rings from leaf scares. Leaf detail: Pinnately compound, diametrically opposed, semi-plumose, very erect, dark green leaves, whitish underneath. Ceroxylon ventricosum, Andean Wax Palms are very slow growers with an attractive, spreading canopy, and can get quite tall (given 100 years or so….) Editing by edric.

Detailed Scientific Description

Fruits globose, orange-red when ripe, 1.5-1.8 cm. in diam., exocarp smooth; fruiting perianth with sepals elliptical-acuminate, 1.0-1.5 mm long, connate in 0.2, lobes exceeding corolla tube, petals 3, elliptical-acuminate, connate in 0.8 mm. Seeds about 1.3 cm. in diam. (Maria Jose Sanin and Gloria Galeano. 2011)/Palmweb.

Ceroxylon ventricosum is characterized by its massive, robust and white stem, by its leaves twisted 90° on distal portion thereby holding the pinnae in a vertical position, the pinnae pendulous and arranged in hardly discernible groups toward the middle of the leaves, staminate flowers with 9-11 stamens and smooth fruits.

Culture

Requirements: This is an emergent palm, and requires protection from wind, and hot dry air when young, filtered light when young, full sun when mature, consistently moist soil, well drained position. Cool, humid and moist, but well drained. That said the plant pictured here is growing in Ventura California, where the summers would be quite hot and dry.

Comments and Curiosities

Conservation: According to the IUCN criteria, considered Vulnerable (VU) in Ecuador (Borchsenius & Skov 1999) and endangered (EN) in Colombia, because of habitat reduction and the small size of the populations. (Maria Jose Sanin and Gloria Galeano. 2011)/Palmweb.

Uses: The split stems are used for fencing and house construction. The fruits are fed to pigs that are set loose on the palm stands during the fruiting season, and because of this, the palms are protected in the pastures and in the forest. (Maria Jose Sanin and Gloria Galeano. 2011)/Palmweb.

Wax is scraped off the stem and burned for illumination, and stems are used for construction purposes (posts, floors, walls); hats and mats are weaved from the pinnae of the spear leaf; the spear leaf is sold during Holy week, to be used on Palm Sunday. (Borchsenius, F. 1998)/Palmweb.

This is a tillering palm, it exhibits saxophone style root growth (it has a heel), keep top third of heel above soil elevation!
