Prumnopitys standleyi

(Buchholz et Gray) de Laub. 1978

Common names

Ciprecillo, cobola, lorito (Rojas et al. 1992 in Moreira and Arnáez 2003).

Taxonomic notes

Syn: Podocarpus standleyi J. Buchholz et N.E. Gray 1948 (Farjon 1998).

Description

Trees up to 25 m tall. Branchlets alternate, spreading. Leaves yew-like, linear, acute or mucronate, 12-25 mm long, 1.5-3.5 mm wide, glaucous beneath, grooved above the midvein. Pollen cones numerous (up to 25), spicately arranged on a branch terminal shoot 3.8-7.6 cm long, each cone 10-13 mm long. Seed cones borne on a peduncle 2.5 cm long, with bracts 1.5 mm long subtending a 17 mm long seed (Dallimore et al. 1967). Note: Moreira and Arnáez (2003) offer a different description that says the pollen cone inflorescence is only 1 cm long and 2.3 mm across, bearing up to 50 pollen cones; and that the mature seed is 9 mm long and 7 mm across.

Distribution and Ecology

Costa Rica, where it is the only endemic gymnosperm, restricted to the Volcan de Poas (10°11' N, 84°14' W, 2708 m) and Cerro Las Vueltas (9°37' N, 83°52' W.) (Farjon 1998). Grows in montane rainforest at 2000 to 3200 m elevation, in areas with 2000-4000 mm annual rainfall and temperature range of 3-25°C (Budowski 1954 in Moreira and Arnáez 2003). See also Chaverri et al. [no date].

Zone 10 (cold hardiness limit between -1°C and +4.4°C) (Bannister and Neuner 2001).

Dendrochronology

Ethnobotany

The wood is relatively heavy (specific gravity of 0.555), dries quickly without defects, and has a fine, uniform texture (Carpio 1992, Standley 1938, both in Moreira and Arnáez 2003). These traits have suited it to use in construction, flooring, indoor decoration, veneer, farming tools, fenceposts, firewood, furniture, and as pulp for paper and cardboard (Budowski 1954, Carpio 1992, Rojas and others 1992, all in Moreira and Arnáez 2003).

Observations

La Amistad Biosphere Reserve looks like a good place to see it.

Remarks

The seeds ripen in 5 months and are ready for harvest in April. To germinate, first soak in water at 22°C for 24 hours. Germination is epigeal. The seedlings' roots bear numerous nodules (Moreira and Arnáez 2003).
