Justification
Drimia hyacinthoides has a restricted range, with an extent of occurrence (EOO) of 9111 km²). It is known from 10 locations, but it is highly likely that it exists at more locations as the northern and eastern parts of its distribution range remains poorly explored. Continuing decline is inferred from ongoing habitat loss and degradation.
Distribution
Endemism
South African endemic
Provincial distribution
Eastern Cape
Range
This species is endemic to the Eastern Cape, where it occurs between East London, Grahamstown and Alexandria.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Grahamstown Grassland Thicket, Bedford Dry Grassland, Doubledrift Karroid Thicket, Buffels Valley Thicket, Buffels Mesic Thicket
Description
It occurs in grassland and open thicket, sometimes in the shelter of bushes.
Threats
This species has lost habitat to urban expansion around Grahamstown and East London, and loss continues. Around Alexandria and the area east of Grahamstown large areas of suitable habitat has been lost to crop cultivation. However north of Grahamstown and between King William's Town and East London most of this species' habitat is still intact. This area is botanically poorly explored, and it is likely that still undiscovered subpopulation exist.
Population

There are very few records of this species, and it was last recorded in 1958. Its distribution range is poorly explored, and field surveys are needed to relocate it in the wild. It is possibly more common than records suggest. A continuing population decline is inferred from ongoing habitat loss and degradation.
