(Pilger) C.N. Page 1989

Common names

Pino hayuelo (Farjon 2008).

Taxonomic notes

Syn: Podocarpus rospigliosii Pilger 1923; Decussocarpus rospigliosii (Pilg.) de Laub. 1969; Nageia rospigliosii (Pilg.) de Laub. 1987 (Farjon 1998).

Description

Trees to 30 m tall and 40 cm dbh, with an oval crown commonly branched from above 3 m. Bark scaly. Leaves light green, 1 cm long, opposite with a whole margin, flattened along the branches, with petioles almost nonexistent. Flowers cream-colored, 1 cm lang, with ovoid green fruits 3 cm long bearing a single seed. A very slow-growing tree (Nieto and Rodriguez 2003).

Distribution and Ecology

Western Venezuela, east Colombia, central Peru (Farjon 1998). Native to the wet forests of the Andes, it grows best at 1500-3500 m elevation, where average annual temperatures are 10°-18°C and annual precipitation is 1500-2500 mm (Nieto and Rodriguez 2003). Zone 10 (cold hardiness limit between -1°C and +4.4°C) (Bannister and Neuner 2001).

The tree needs constant humidity and cloudines, which it finds in habitats that include pre-mountainous wet and very wet forest, low mountainous wet and very wet forest, and mountainous pluvial forest. The tree develops best on gentle slopes, fertile river lowlands, plateaus, and small depressions. It grows in wet, clay or clay-sand, deep, relatively fertile soils with good to slow drainage and acid pH (Nieto and Rodriguez 2003).

The IUCN reports that this taxon is "vulnerable." It faces a high risk of extinction in the wild due to exploitation and habitat loss/decline, which have led to recent and ongoing declines in population size.

The wood is easily worked, used for furniture, veneer, moldings, wood shaving boards, boxes, and general cabinetry. It is also used for light poles, paper pulp, and pencils (Nieto and Rodriguez 2003).
