They have flowers with petals and petaloid sepals (tepals) with compound pistils. The genus is named for Austrian and Russian botanist Wilibald Swibert Joseph Gottlieb von Besser (1784–1842). Bessera elegans, called coral drops, is cultivated and is a half-hardy Mexican herbaceous plant growing from corms with drooping terminal umbels of showy red-and-white colored flowers.
