The specific epithet is named after Christopher Maitland Stocken, who discovered it in 1962 in Bornos.^[1] It is native to Spain,^[2] where it is endemic to grasslands growing in calcareous soil on formations made from calcarenite (a type of limestone)^[3] west of Cádiz in Andalusia. It is currently listed as critically endangered. In 1993, the number of individuals belonging to this species was estimated to be below 2000.
