Adults of Bitis inornata average 25–40 cm (about 10–16 inches) in total length (including tail), with a maximum recorded total length of 45 cm (18 in).[3]
The type locality is listed as "Sneeuwbergen, or Snow Mountains, ... immediately behind the village of Graaff Raynet" (Eastern Cape Province, South Africa).[2]
Spawls and Branch (1995) described it as known only from two isolated populations in southern Cape Province in South Africa: the first in the east, limited to the montane grassland of the Sneeuberge, from north of Graaff-ReinettoCradock. A second population was discovered relatively recently on the upper slopes of the Cederberg in the west.[4]
