Cyclopia subternata, the vlei honeybush, is a shrub belonging to the genus Cyclopia. The species is endemic to the Western Cape and occurs from the Langeberg to the Tsitsikamma Mountains. It has a range of 5 200 km<sup>2</sup> and although it is still abundant, the population is declining due to the fact that it is over-collected by tea traders. The plant is part of the fynbos and a protection program is needed to preserve the plant; it does not resprout after the branches have been picked.
The tree's FSA number is 224.4.
