4. Euphorbia louwii Leach (1980: 207) View in CoL .

Type:— SOUTH AFRICA. Transvaal (Limpopo): ± 14 km east of Marken, 900 m, 1 November 1975, Leach et al. 15555 (holotype PRE!, isotypes K!, SRGH).

Discussion:— Euphorbia louwii is known from a small area around the hamlet of Marken, north-east of the Waterberg in Limpopo Province, South Africa. It is most easily distinguished from the other members of the E. schinzii -complex by the 5- to 7-angled branches and the considerably longer and more slender leaf-rudiments. Five spines and prickles per spine-shield is typical of E. louwii and is also found occasionally in E. aeruginosa . The two also share a very similar colour of the branches and spine-shields, though the pale streak between the angles in E. louwii is missing in E. aeruginosa .
