Scientific Name
Syncolostemon ramosus (Codd) D.F.Otieno
Higher Classification
Hemizygia ramosa Codd
National Status
Status and Criteria
Vulnerable D2
Assessment Date
L. von Staden & H. Mtshali
A highly range-restricted and poorly known species, occurring at two locations and potentially threatened by habitat degradation due to overgrazing.
South African endemic
Provincial distribution
Southern end of the Lebombo Mountains near Mkuze.
Habitat and Ecology
Major system
Major habitats
Southern Lebombo Bushveld
Shallow soil among rocks in open and closed woodland.
A large proportion of this species' habitat is protected within the Mkuze Game Reserve and Umbombo Mountain Nature Reserve. Outside protected areas, there are some parts of the Lebombo Mountains that are affected by heavy overgrazing, which has resulted in a loss of vegetation cover and erosion in places.

Syncolostemon ramosus is a highly localized species and is known from only three collections. It was last recorded in 1984. There are currently two known locations, but it is likely that more exist as its habitat has not been fully explored. The current population trend is not known, and field surveys are needed to determine whether grazing has a negative impact on the population.
