Long known and very popular among succulent fanciers Gasteria carinata var. verrucosa (more commonly known as Gasteria verrucosa) is a peculiar looking plant with two-ranked, dull-green, leaves densely roughened with small, pearly-white excrescences and with grooved upper surfaces. It is probably the best-known example of a Gasteria species with very rough leaves. The name verrucosa, signifies warty or rough. The most popular form has the leaves being completely covered with white tubercles, and in some forms, the tubercles forming ornamental stripes of white bumps over both the ventral and dorsal surfaces. It is one of the most variable species in the genus. Variability includes a very large form (leaves up to 280 mm long) at Infanta (Breede River mouth) and a form with linear, channelled leaves at Herbertsdale. It is a small to medium-sized acaulescent succulent. It offsets freely from the base and soon forms a dense cluster with dull green speckled leaves. Dimension of the clumps 3 to 18 cm tall and 15 to 80 cm wide.
