Ceroxylon vogelianum is widely distributed through the Andes from Venezuela to Colombia, Ecuador, and Peru, in humid montane forest, at (1900-)2200-2900 m. Although it is one of the most common palms of the high tropical Andes, it never forms extense stands, and is commonly sparse on mountain ridges.

Discussion

Conservation

  • In Venezuela, C. vogelianum has been recorded as Endangered (EN) according to the IUCN criteria, mainly due to deforestation practices along the Andes (Llamosas et al. 2003). In Colombia the species was only considered Near Threatened (NT; Galeano et al. 2005) because of its wide distribution, but more studies need to be done related to the population dynamics and reproductive biology of this species, as it is expected to be endangered due to the deforestation process due to agricultural activity in the Andes of Colombia.

Description

  • Understorey or subcanopy palm. Stem solitary, to 10 m tall, ca. 10 cm in diameter, greenish grey, with dark leaf scars. Leaves 1-1.5 m long; pinnae 70-80 on each side, inserted in groups and spreading in different planes, with pendulous distal half, the central ones 30-40 cm long, 20-25 mm wide, below with a thin, light grey to brown wax layer. Inflorescences curved, becoming pendulous in fruit, 120-160 cm long, branched 2 times. Male flowers with 6 stamens. Fruits globose, bluish green, often becoming dull orange just before dropping, slightly warty, 13-15 mm in diameter. (Borchsenius F., Borgtoft-Pedersen H. and Baslev H. 1998.
