Conservation status

Pinus oocarpa

Schiede ex Schlectendahl 1838

Common names

Pino de colorado, pino de ocote, pino prieto, pino amarillo [Spanish].

Taxonomic notes

Two varieties, oocarpa and trifoliata. Pinus tecunumanii has been placed in synonymy, but is now regarded as a distinct species (Farjon and Styles 1997). Other closely-related species include P. greggii, P. jaliscana, P. patula, P. praetermissa, and P. pringlei, all of which also are native to Mexico.

Pinus oocarpa var. oocarpa syns: Pinus oocarpoides Lindl. ex Loudon 1842, Pinus oocarpa var. oocarpoides (Lindl. ex Loudon) Endlicher 1847; Pinus oocarpa var. manzanoi Martínez 1940 (Farjon 1998).

Pinus oocarpa var. trifoliata Martínez 1948 syn: P. oocarpa forma trifoliata Martínez 1945 (Farjon 1998), P. luzmariae Pérez de la Rosa 1998. I haven't seen much on P. luzmariae; it was described in Spanish and doesn't seem to have been widely recognized. For the time being I'm keeping it as a synonym of P. oocarpa var. trifoliata.

Description

Distribution and Ecology

Mexico, Guatemala, Honduras, El Salvador and NW Nicaragua. See also Thompson et al. (1999). Trees reported from Belize (Critchfield and Little 1966, Perry 1991) are now assigned to P. tecunumanii (Farjon and Styles 1997). Var. oocarpa is native throughout the range described, while var. trifoliata is restricted to Honduras and Mexico: Durango, Hidalgo, Jalisco, Michoacan, Oaxaca (Farjon 1998, Conifer Specialist Group 1998).

Hardy to Zone 9 (cold hardiness limit between -6.6°C and -1.1°C) (Bannister and Neuner 2001).

Observations

In El Salvador, it occurs with Pinus maximinoi on Cerro el Pital in La Palma town and above, at 900-1500 m elevation. While you're there, from 1500-2500 m the forest is mixed with Pinus tecunumanii and Pinus pseudostrobus var. apulcensis, and above 2000 m it is easy to find pure and mixed forests of Pinus ayacahuite (Fernando Tobar email 2008.11.12).

Also in El Salvador, on Cerro Montecristo, there natural forests of Pinus oocarpa var. oocarpa on the lowest peaks, again mixed with Pinus maximinoi. On the highest peaks you can find Pinus pseudostrobus var. pseudostrobus with Pinus tecunumanii. Also, on the highest part of the mountain in Quercus-dominated cloud forests, is the only place in El Salvador where Podocarpus oleifolius grows in the wild (Fernando Tobar email 2008.11.12).

Remarks

This species is a principal host for the dwarf mistletoe Arceuthobium aureum subsp. petersonii in Oaxaca and Chiapas, and is the sole host of A. hondurense in Honduras (Hawksworth and Wiens 1996).
