This member of the Euphorbiaceae family was given this name by Ferdinand Albin Pax in 1895. It is found in Kenya, Tanzania and Somalia, growing in a well drained soil with some water and some to lots of sun. The caudex can grow to 16 or even 20 centimetres in diameter, the entire plant to 40 or even 200 centimetres in height. The flowers are red.
The genera name from the Greek words ἰατρός; iatros, meaning 'physician', and τροφή; trophe meaning 'nutrition', as to medicinal uses. The species name after Franz Ludwig Stuhlmann, 1863-1928, a German naturalist, zoologist and African explorer.
