Branching allows the Salvia disermas plant to achieve a broad and dense shape, often wider than it is tall.
Most of the inflorescences are erect, dead straight and beady from the evenly spaced flower whorls. Smaller branches of the leafless inflorescences are sometimes present, while curved spikes may occur.
The bushes in picture were seen during October, growing in deep sandy soil along the bed of an occasional stream, running through stony karoid hills of the western Little Karoo (Manning, 2009; Shearing and Van Heerden, 2008; iNaturalist).
