Habitat
The syntypes of M. nervosa are Krauss 268 and 268 1/2. The latter could not be traced, while sheets of the former are to be found at Kew and Berlin. The Kew specimen of Krauss 268 has been selected as the lectotype, because it is a complete specimen with flowers, whereas the Berlin specimen consists merely of fragments of several leaves in a capsule.
Use
5. Maerua nervosa (Hochst.)Oliv. in F.T.A. 1 : 84 (1868) excl. descr. et specim. cit.; Sim, For. Fl. Port. E. Afr. 9 (1909); Gilg & Ben. in Bot. Jahrb. 53 : 244 (1915); Wild in F.Z. 1 : 221 (1960). Syntypes: Natal, near Durban, Krauss 268 (K, lecto.!; B!; PRE, photos.); Krauss 268 1/2 (not traced).
Range
M. nervosa is a shrub found in dune scrub or forest along the coast of Natal and Mozambique and on Inhaca Island off Mozambique. It also occurs n Rhodesia, though it was not included in the treat­ment of Maerua in Flora Zambesiaca: a specimen in BOL, Teague 319, from the Odanzi (probably Odzani) Valley near Umtali is undoubtedly M. ner­vosa.
