Erepsia inclaudens is one of a few of the 27 Erepsia species that do not close their flowers at night. This earned them the common name of altydvygies (always mesembs). What characterise all 27 is: sharp leaf tips, a unique flower structure involving a hollow, concave ovary that forms a tube and makes the staminodes bend down and cover the stamens. The fruits are woody and lack closing bodies. Most of the species are found in the Western Cape with a few in the Eastern Cape.
E. inclaudens has short three-sided leaves, triangular in cross-section, tapering to sharp points. The margins near the tips tend to be purple, maybe more so seasonally, with a faint whitish ridge.
The distribution of this species lies to the west in the overall distribution of its genus, from the Kogelberg to about Bredasdorp and the Overberg. It grows in rocky crevices (Manning, 2007; Smith, et al, 1998).
