armstrongii) is a dwarf succulent plant native to South Africa, in the genus Gasteria.

In some classification schemes, it is even classed as a variety within this species, and in cultivation G. armstrongii can resemble juvenile plants of G. nitida.

For those who treat it as a separate species, Gasteria armstrongii can be distinguished by its very dark, retuse, distichous, roughly tuberculate leaves.

It was reduced to the variety armstrongii of Gasteria nitida by Ernst van Jaarsveld in 1992, a status accepted by the World Checklist of Selected Plant Families.

At the edge of its habitat it gradually transforms into Gasteria nitida, making the two species part of a continuum.
