Erepsia inclaudens is one of a few of the 27 Erepsia species of vygies 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.
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 in the southwest of the Western Cape, from the Kogelberg to about Bredasdorp and the Overberg, overlapping with the fynbos region where many members of the genus overall are distributed.
The habitat is largely rocky sandstone crevices in fynbos. The habitat population is deemed of least concern early in the twenty first century (Manning, 2007; Smith, et al, 1998; iNaturalist; http://redlist.sanbi.org).
