Notes
Hargreaves has named one of his collections, no. 497 from Malawi, Machinga Distr., Mangombo Hill near Sonje, as Euphorbia tetracanthoides (Succ. Spurges Malawi: 42 (1987)), but this identification is extremely unlikely.I have not seen the specimen, but the locality and his sketches suggest it may be E. contorta
