Higher Classification | Dicotyledons |
Family | OROBANCHACEAE |
Synonyms | Harveya sulphurea Hiern |
Common Names | Geelinkblom (a) |
National Status |
Status and Criteria | Rare |
Assessment Date | 2011/03/29 |
Assessor(s) | N.A. Helme & L. von Staden |
Justification | A poorly known, seldom collected plant occurring at extremely low densities. It may be threatened if it is found to also occur on deeper, sandy soils which are being converted to crop fields. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape, Western Cape |
Range | Bokkeveld Escarpment and northern Cederberg. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Cederberg Sandstone Fynbos, Nardouw Sandstone Fynbos, Graafwater Sandstone Fynbos, Bokkeveld Sandstone Fynbos |
Description | Rocky sandstone slopes. |
Threats |
| This species is currently too poorly known to determine threats. Two recent collections are from rocky mountain slopes where plants are not threatened. Some older collections without habitat notes are from areas where fynbos on deep sandy soils is being converted to crop fields, and this species may be threatened if it also occurs on deep sands. |
Population |
Plants are extremely rare and localized, with seldom more than two or three plants seen. This taxon is rarely collected.
|
Population trend | Unknown |
Notes |
| The bright yellow flowers of subsp. sulphurea are distinctive, however, in pressed material it is indistinguishable from most specimens of subsp. purpurea, if corolla colour is not recorded on the specimen label. |
