2. Aloe barendii Klopper & Gideon F.Sm. , nom. nov.

Haworthia tenuifolia Engler (1889: 2 , t. 1). Chortolirion tenuifolium (Engl.) Berger (1908: 73) . Type:— SOUTH AFRICA. Northern Cape: Kalahari Region, near Kuruman, R. Marloth 1049 (holotype B100165765!, isotype PRE0037837-0!).

Etymology: —Since the name Aloe tenuifolia Lamarck (1783: 87) already exists, this combination is not available for Chortolirion tenuifolium . The new name commemorates Barend [Ben] Hermanus Groenewald (1905–1976), who described several new aloes from South Africa during the 1930s and wrote the first book on the aloes of southern Africa that represented an up-to-date treatment for the subcontinent ( Groenewald 1941). Despite his valuable contributions towards our understanding of aloes in southern Africa, he did not receive the recognition he deserves and has never been commemorated in the genus Aloe ( Anonymous 2010, Figueiredo & Smith 2010).
