This member of the Orchidaceae family was given this name by Antonio José Cavanilles in 1793. It is found in southern Europe and northern Africa, growing in grassland in a well drained soil with some to lots of water and some to lots of sun. The bulbs can grow to two centimetres, the plant up to 30 centimetres in height. The flowers are yellow, blue-grey and maroon. The pollen is deposit on the abdomen of the bees.
The genera name means 'brow', perhaps as to larger sepals than petals. The species name means 'yellow'. I am not sure the caudex will appreciate to be exposed.
