This member of the Euphorbiaceae family was given this name by Alan Radcliffe-Smith in 1991. It seems to be endemic to Boswana, found in the eastern part, growing in a well drained soil with quite some water and some sun. The caudex is a large reddish swollen rootstock, the entire plant to 30 centimetres in height. The flowers are yellow.
The genera name from the Greek words ἰατρός; iatros, meaning 'physician', and τροφή; trophe meaning 'nutrition', as to medicinal uses. The species name indicates it originates from Botswana.
