Its nearest affinity is H. atrofusca, but it differs from that species by its smooth end-area, and shorter leaves. From: Scott, CL. 1985. The genus Haworthia (Liliaceae): a taxonomic revision. Aloe Books, Johannesburg. [All rights reserved]
It is nearest to H. retusa v. mutica (Haw.) Bak., but is easily distinguished by its much longer and more pointed leaves which are more upright. From: Smith, GG. 1945. Some new species and varieties in the genus Haworthia IV. J. S. African Bot. 11: 65-78. [CC BY] As: Haworthia otzenii G.G.Sm.
It grows in exposed positions, mainly in rock crevices in clay-sandy soil. This area receives an annual rainfall of 300 to 500 mm occurring during the winter months, often as soaking drizzle. The summers are hot, the winters cool and wet. H. mutica grows in a firm hard soil with pH 6. From: Scott, CL. 1985. The genus Haworthia (Liliaceae): a taxonomic revision. Aloe Books, Johannesburg.
