Marasmodes oligocephala is a range-restricted and highly localized habitat specialist. Currently, four subpopulations remain on small renosterveld remnants within an area of 7 km². At two of these locations, the species is fairly common, with around 200 plants occurring at each. A third subpopulation is very small, consisting of about 10 plants. The fourth subpopulation was last observed in 2006, and the number of plants was not counted. This subpopulation occurs on a tiny fragment (2 ha), and is unlikely to be large. It is therefore estimated that the population numbers fewer than 500 mature individuals, and continues to decline due to ongoing habitat loss and degradation.
