Podocarpus aracensis

de Laub. & Silba 1988

Common names

None are listed in the usual sources. It seems unlikely that native peoples distinguish it from other podocarps in the region. Silba (1990) gave it the common name "Araca podoberry" which seems not to have received any subsequent use.

Taxonomic notes

The species is poorly known, with few herbarium collections (18 records as of early 2023) and no molecular analyses. All tropical South American species analyzed to date share a clade within Podocarpus (Knopf et al. 2011), so it is likely that P. aracensis is in the same group.

Description

Shrubs or trees to 6 m tall and 20 cm dbh. Buds erect, scales elongated and 4-9 mm long by 0.5 mm wide, free at the apex. Foliage densely arranged. Leaves linear, narrow, 2.8-8 cm long by 4.5-7 mm wide, narrowed at the base to a petiole 2-3 mm long, midrib a sunken groove, margins recurved, apex broadly acute. Pollen cone solitary or in small groups, on a scaly peduncle 9 mm long, basal bracts to 2 mm long and acute; pollen cone oblong-cylindric, 17-20 × 2-2.5 mm, solitary or in small groups. Female cones not seen. P. buchholzii is overall similar, but this is the only South American Podocarpus that does not have sessile pollen cones (de Laubenfels and Silba 1988, Silba 1990).

Distribution and Ecology

Brazil: Amazonas (Serra do Araçá, Cerro Neblina?); Venezuela: Amazonas (Cerro Yavi and perhaps Murey Tepui [Macizo del Chimantá]); at elevations of ca. 1200 m in Brazil and 2100 m in Venezuela. Occurs on tepuis, along streams in shrubby vegetation or dwarf forest (Farjon 2010, 2013). This GBIF Map (accessed 2023.01.04) shows the locations of the 15 georeferenced collections.

The IUCN has assigned this species a "Least Concern" conservation status. Although its distribution is still very poorly known, still no threats are known to affect this species (Farjon 2013).

Remarkable Specimens

No data as of 2023.01.04.

Ethnobotany

No human use is known; the species is rare and occurs only in remote areas (Farjon 2010).

Observations

No records on iNaturalist as of 2023.01.04.

Remarks

The epithet refers to the type locality, the Serra do Araçá in Brazil.
