Syst. 28: 395. 1900 [Dicot.: Legum.], nom. cons. prop. Lectotypus (hic designatus): Tanzania, Kilosa, Kidodi, 1898, Goetze 387 (K; isolectotypus: E). (=) Acacia andongensis Welw. ex Hiern, Cat. Afr. Pl. 1: 314. Dec 1896, nom. rej. prop. Lectotypus (vide Torre in Carrisso & al., Consp. Fl. Angol. 2: 277. 1956): Angola, Cuanza Norte, Pungo Andongo, Welwitsch 1814 (LISU; isolectotypi: BM, K). Acacia andongensis was first described by Hiern in his Catalogue of Welwitsch’s African Plants (1896), from a Welwitsch specimen, collected at Pungo Andongo, Cuanza Norte district, Angola. The species was tentatively included by Baker (Legum. Trop. Africa 3: 832. 1930), who was followed by Torre (l.c.). Ross (in Bothalia 11: 291. 1974 and Mem. Bot. Surv. South Africa 44: 82. 1979) concluded that the species was distinct but very closely related to A. goetzei Harms subsp. microphylla Brenan, and differed solely in having sparingly pubescent calyces. Acacia andongensis is still only known from the type collection and a collection from Cuanza Sul (Raimundo Matos & Figueira 697, LISC) also in Angola. Locke (Legum. Africa Checkl.: 62. 1989) included the name only provisionally. Acacia goetzei is a well known and widespread species, first described by Harms (in Bot. Jahrb. Syst. 28: 395. 1900), based on a single gathering from modern Tanzania, cited above. The holotype of A. goetzei, a flowering specimen originally preserved at B, is no longer extant (R. Vogt, pers. comm.) but isotypes occur at K and E. The isotype of Goetzei 387 held at Kew is designated above as lectotype. Since its publication the name has been widely accepted in the literature, including in Baker (l.c.: 830), Brenan & Greenway (Checkl. Forest Trees Shrubs Brit. Empire 5(2): 329. 1949), 1001
