Scientific Name | Clematis massoniana DC. |
Higher Classification | Dicotyledons |
Family | RANUNCULACEAE |
Synonyms | Clematis orientalis L. subsp. normalis Kuntze var. albida (Klotzsch) Kuntze forma massoniana (DC.) Kuntze |
National Status |
Status and Criteria | Data Deficient - Taxonomically Problematic |
Assessment Date | 2017/08/11 |
Assessor(s) | L. von Staden |
Justification | Clematis massoniana is a taxonomically problematic and very poorly known species. Nothing is known about its distribution or habitat, and it has not been recorded in the wild for more than 100 years, but may be overlooked due to taxonomic confusion within Clematis. Based on currently available information, its risk of extinction cannot be assessed. |
Distribution |
Endemism | South African endemic |
Range | Its distribution is unknown. The type collection (Masson s.n.) has no specific locality information. Wang (2004) cites one specimen, made from material cultivated at Kew from seed sent from the Karoo. |
Habitat and Ecology |
Major system | Terrestrial |
Description | Its habitat is unknown. |
Population |
Population trend | Unknown |
Notes |
| Harvey (1859) considered Clematis massoniana to be conspecific with the widespread and highly variable Clematis brachiata. Essig (2004), in a preliminary review of African Clematis, listed C. massoniana among unresolved names, and suggested that it is possibly synonymous with C. brachiata. In a review of the C. brachiata complex, Wang (2004) reinstated C. massoniana, but did not examine the type specimen. Only one collection is cited, which originated in cultivation. |
