This member of the Euphorbiaceae family was given this name by Peter René Oscar Bally in 1959. It is found in Tanzania, growing in a well drained soil with some water and lots of sun. The caudex can grow to four centimetres, the stem up to twelve centimetres height.
The genera name from the Greek monos; 'one' and -aden; 'gland', referring to the solitary gland.
The species name means 'graceful' or 'slender' for the growth form, not the caudex!
