Roupala montana Aubl.

국표에 없다.

Roupala montana is a species of shrub or tree in the family Proteaceae which is native to much of the Neotropics. It is a morphologically variable species with four recognised varieties. The species is used medicinally in Venezuela, and as an aphrodisiac in Trinidad and Tobago and Venezuela.

Description

The species ranges in size from shrubs to trees, usually 1–8 metres (3–26 ft) tall, but sometimes ranging up to 25 metres (82 ft) tall. The leaves are usually simple in adult plants, but are occasionally compound.  It is an ochlospecies—a species that is highly variable morphologically, and that variability "cannot be satisfactorily accommodated within a formal classification"—with a very wide distribution. Consequently, a large number of species and varieties have been described based on variations between collections.

Taxonomy

The species was first described by Jean Baptiste Christophore Fusée Aublet in 1775. The name Roupala was based on roupale, a name used locally in French Guiana. The Latin specific epithet montana refers to mountains or coming from mountains.

In their 2007 monograph, Ghillean Prance, Katie S. Edwards and coauthors recognised four named varieties within the species: R. montana var. montana (the "nominate" variety, based on Aublet's original description of the species), R. montana var. brasiliensis (Klotzsch) K.S.Edwards, R. montana var. impressiuscula (Mez) K.S.Edwards and R. montana var. paraensis (Sleumer) K.S.Edwards.

Distribution

Roupala montana ranges from Mexico in the north, through Central America, to Trinidad and Tobago, and across South America to southern Bolivia, Argentina, Paraguay and southern Brazil.
