Taxonomy [top]

Kingdom Phylum Class Order Family
PLANTAE TRACHEOPHYTA MAGNOLIOPSIDA ARISTOLOCHIALES ARISTOLOCHIACEAE

Scientific Name: Pararistolochia goldieana
Species Authority: (Hook.f.) Hutch. & Dalz.

Assessment Information [top]

Red List Category & Criteria: Vulnerable A2c ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Cheek, M.
Reviewer(s): Hilton-Taylor, C. & Pollock, C.M. (Red List Programme Office)
Justification:
Although widespread, it is rare. Despite intensive surveys over several years at Mt Cameroon, only a single individual was found (Cable and Cheek 1998). Forest loss has been extensive throughout Sierra Leone and Nigeria and is continuing; it is unlikely that this plant survives at its Calibar or Lagos localities, for example.

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Found in lowland evergreen forest, often seen in disturbed areas. This climber almost certainly has the largest flowers (c. 30 × 30 × 30 cm) of any African species of flowering plant. It is the African equivalent of the S.E. Asian Rafflesia, matching it in habitat, colour, size and scent of the flowers. The life cycle of this species is unknown, but it appears to be a perennial, producing annual shoots. It is estimated that a generation might last for 10 years.
Systems: Terrestrial

Threats [top]

Major Threat(s): Threatened by clearance of forest for timber and agriculture.

Conservation Actions [top]

Conservation Actions: A plant of this species in semi-natural forest at Limbe Botanic Garden in Cameroon offers excellent possibilities for research into the environmental and propagation requirements of P. goldieana. The subpopulation at Mahole (Bakossi F.R.) offers a good chance of conserving this magnificent species in the wild, possibly by a poster education scheme. Flowering plants offer the potential to attract tourists.
