Status and Criteria | Data Deficient - Insufficient Information |

Assessor(s) | H. Mtshali, F. Daniels, F. Cholo & D.A. Kamundi |
Justification | Bolbitis heudelotii is a poorly known species with one record, collected in 1931. Not enough is known about the population of this species to determine its risk of extinction. |
Distribution |
Endemism | Not endemic to South Africa |
Provincial distribution | Limpopo |
Range | This species is widespread across tropical Africa, but rare in southern Africa, where it is known from sporadic occurrences in Mozambique, Zimbabwe and Limpopo Province, South Africa. |
Habitat and Ecology |
Major system | Freshwater |
Major habitats | Forest, Savanna |
Description | It is an aquatic plant growing on rocks in and along shaded rivers and streams with fast-flowing water, often near waterfalls. |
Threats |
| The area where this species was last recorded has been largely converted to timber plantations, which may have had an impact on water flow in streams. |
Population |
This species is poorly known in South Africa, where it was recorded once in 1931. The locality description is imprecise, and therefore it is not certain whether the subpopulation persists or not. Field surveys are needed to confirm its presence, as it is possibly locally extinct due to habitat loss or degradation. The population trend, as well as its size is not known, but it may be small. Recent field observations indicate that it is still present in many localities outside South Africa, but the South African population is isolated from the rest of the species' known range, and therefore probability of recolonization of habitat within South Africa from sources outside South Africa may be low.
