Tree to 25(–30) m, trunk straight, to 1.5 m dbh, shrubby in exposed sites at altitude. Bark thin, yellowish-brown and smooth at first, grey-brown and scaly with age. Branchlets with prominent grooves and leaf scars. Terminal buds of leading shoots subglobose, 3–5 mm wide, with short, imbricate, rounded or ovate scales 3–4 mm long; lateral buds globose with thick, rounded scales. Leaves of established trees leathery, lanceolate to linear, extremely variable even on the same tree, (1.5–)4–9 × (0.5–)0.7–1.2 cm, largest on shaded shoots (much larger on juvenile plants, to 15 × 2 cm), straight to slightly curved, base tapering, petiolate, apex tapering to an acute or obtuse apex; upper surface dark green with a narrow midrib in a central groove; lower surface dull green, midrib forming a small but conspicuous ridge, sometimes grooved near the tip, with two stomatal bands either side. Pollen cones sessile, solitary, cylindrical, 25–30 × 3–4 mm. Seed cones solitary on short peduncles, with two bracts which fuse to become a swollen, fleshy receptacle 6–10 mm long, maturing red. Seed including the epimatium ovoid-globose, olive green, 7–8 mm long. (Farjon 2017).

The New World Podocarpus oleifolius is a component of high altitude cloud forest from southern Mexico to Peru. There are two accepted subspecies: subsp. costaricensis (J.Buchholz & N.E.Gray) Silba, distributed from southern Mexico to Panama; and subsp. oleifolius, distributed in north west South America (Plants of the World Online 2023). Both have a tenuous presence in temperate cultivation. The only plant traced growing outdoors in our proper study area is one of Costa Rican provenance (subsp. costaricensis) at Tregrehan, Cornwall, UK, which has made a wispy, multistemmed shrub c. 2.5 m tall, its best stem about 4 cm dbh (pers. obs. 2022). Rob Nicholson introduced material from Colombia (subsp. oleifolius) to the US in 1998 under Nicholson 98/484 and this has found its way into several botanic gardens, including Edinburgh in the UK, where it is maintained under glass (Royal Botanic Garden Edinburgh 2022). Neither taxon is grown at Florida’s Montgomery Botanical Center (Royal Botanic Garden Edinburgh 2023) but it probably has some potential as an ornamental in the southern states and in southern California, and in regions like Australia. Material sourced from the upper limits of its altitudinal range should be sought out where possible, even in these very mild areas.
