Haworthia reticulata var. subregularis is a stemless leaf succulent, a robust variety of H. reticulata. The leaf rosettes may reach a diameter of 8 cm and tend to form clumps.
The thickly succulent leaves are smooth and nearly flat on their inside surfaces. They are amply rounded and keeled at the back and acutely pointed at their tips. Leaf colour is pale yellow-green, sometimes darker or pinkish near the leaf tips, related to the translucent windows found in the upper leaf parts. Pale spots are present upon the leaf surfaces, scattered or somewhat in rows. Leaves become 6 cm long and 2 cm wide.
Membranous sterile bracts, triangular in shape, grow on the peduncle of the inflorescence, that stands 27 cm tall, bearing a single raceme. The white thinly tubular flowers have narrow segments, the tips of which curve back strongly, displaying thin brown longitudinal lines inside as on the outside on their keels.
The distribution of H. reticulata var. subregularis is in the lower Hex River Valley and towards Worcester in the Western Cape. The plants grow in scrub on shale slopes. The variety is not considered to be threatened in its habitat early in the twenty first century (Scott, 1985; http://haworthia-gasteria.blogspot.co.za; www.redlist.sanbi.org).
