Drimia is a genus of bulbous flowering plants in the family Asparagaceae (subfamily Scilloideae, formerly treated as the family Hyacinthaceae), placed in the order Asparagales. The genus encompasses approximately 130 accepted species distributed across Africa — including Madagascar — the Mediterranean region, and southern Asia, with the greatest diversity concentrated in the semi-arid, winter-rainfall regions of southern Africa.
Plants in the genus are typically deciduous, though a few species are evergreen, and grow from bulbs that may be positioned underground or at or near the soil surface. Each bulb produces one to several leaves, which are often already dry by the time the plant flowers. The inflorescence is a raceme bearing one to many flowers; a distinguishing character of the tribe Urgineeae, to which Drimia belongs, is that at least the lower bracts of the inflorescence bear spurs. Individual flowers are short-lived, lasting only one to two days, and bear white to yellowish-green or brownish tepals that are either free or fused into a short basal tube, frequently with a darker midrib (keel). After fertilization, an ovoid capsule develops, containing several black, winged seeds per locule.
When broadly circumscribed — as accepted by the World Checklist of Selected Plant Families — Drimia absorbs several genera formerly treated as distinct, including Litanthus, Rhodocodon, Schizobasis, and Urginea. The most widely recognized species in the genus is the sea squill, Drimia maritima (long known as Urginea maritima), a large-bulbed Mediterranean plant with a long history of medicinal and economic use. The boundaries within Scilloideae remain unsettled: some authorities prefer to keep a larger number of segregated genera, while others accept the broad circumscription.
The genus was formally described in the fourth edition of Species Plantarum (1799) by Carl Ludwig Willdenow, based on work by Nikolaus Joseph von Jacquin, who coined the name from the Greek word drimys, meaning "bitter" or "acrid" — a reference to the taste of the bulb.
Etymology
The name Drimia is derived from the Greek δριμύς (drimys), meaning "bitter" or "acrid," referring to the pungent taste of the bulb. The name was coined by Nikolaus Joseph von Jacquin when he described the type species Drimia elata in 1797, and was formally published by Carl Ludwig Willdenow in 1799.
Distribution
Drimia occurs across Africa (including Madagascar), the Mediterranean region, and southern Asia, with approximately half of all species endemic to southern Africa. Species diversity is greatest in semi-arid zones with seasonal winter rainfall, and the genus broadly favors habitats with pronounced seasonal dryness.
Taxonomy Notes
Drimia is placed in the tribe Urgineeae within subfamily Scilloideae of Asparagaceae (or subfamily Urgineoideae of the family Hyacinthaceae, depending on the classification followed). The genus boundaries within Scilloideae are in a recognized "state of flux": a broad circumscription — accepted by the World Checklist of Selected Plant Families and supported by molecular phylogenetic data — folds in Urginea, Litanthus, Rhadamanthus, Rhodocodon, and Schizobasis, while other treatments maintain these as separate genera. As of September 2025, Plants of the World Online accepts 130 species.
