Drimia is a genus in the Hyacinthaceae family (or expanded Asparagaceae family) of bulbous plants that are deciduous or rarely evergreen. Bulbs can be small or large, subterranean or growing on or close to the ground. The one or more leaves are often dry at flowering. In 2004 a number of genera were included in this genus once separated as other genera. Some of these genera were formerly monotypic with species formerly included in other genera, like Ledurgia, Boosia, Geschollia and a couple had two species, like Ebertia and Rhadamanthopsis. Others with more species that were included were Urginavia, Indurgia and Thuranthos. They included the Mediterranean, North African and western Asiatic species formerly in Urginea in Drimia but not everyone agrees. African genera once separated as Litanthus, Rhadamanthus, Schizobasis and Tenicroa are now included in Drimia. These plants are common in seasonally dry or semi-arid regions and many of them flower in late spring or summer regardless of the rainfall pattern.

Drimia macrocentra, previously known as Urginea lilacina and Urginea macrocentra is a South African indigenous species from the Eastern Cape and KwaZulu-Natal Provinces. Commonly known as Snakes Head in English and Slangkop in Afrikaans it received this name due to its sinuous inflorescence that is said to resemble the flared hood of a rearing cobra.
