Galenia glandulifera has an extent of occurrence (EOO) of 18 180 km². There are between 10 and 15 locations, and it is suspected to be declining due to overgrazing.
South African endemic
Provincial distribution
Northern Cape, Western Cape
This species is endemic to the Great Karoo, where it occurs from Whitehill to Prince Albert.
Habitat and Ecology
Major system
Major habitats
Nama Karoo
It occurs in stony soil in karroid shrubland.
Some Galenia species are known to be unpalatable and increase under conditions of overgrazing, but this species appears to be sensitive to overgrazing. Recent observations are mainly from road verges, which are areas between roads and fences where there is less grazing pressure, and notes on specimens also indicate that it is not found in vegetation that has been grazed. Another indication of its sensitivity to grazing is that it was only collected once during extensive recent field surveys as part of the Karoo BioGaps Project (2015-2018). Ongoing aridification of the Karoo linked to climate change is also likely to place pressure on this species.

This species is known from 11 extant subpopulations, but is possibly under-collected. Notes on herbarium specimens indicate that this species is occasional in its distribution. A continuing decline is inferred from widespread overgrazing occurring across its range.
