Galanthus
Galanthus (snowdrop; Greek gála "milk", ánthos "flower") is a small genus of about 20 species of bulbous perennial herbaceous plants in the family Amaryllidaceae. Most flower in winter, before the vernal equinox (20 or 21 March in the Northern Hemisphere), but certain species flower in early spring and late autumn.
Snowdrops are sometimes confused with the two related genera within Galantheae, snowflakes Leucojum and Acis.
Description
All species of Galanthus are perennial, herbaceous plants which grow from bulbs. Each bulb generally produces just two or three linear leaves and an erect, leafless scape (flowering stalk), which bears at the top a pair of bract-like spathe valves joined by a papery membrane. From between them emerges a solitary, pendulous, bell-shaped white flower, held on a slender pedicel. The flower has no petals: it consists of six tepals, the outer three being larger and more convex than the inner series. The six anthers open by pores or short slits. The ovary is three-celled, ripening into a three-celled capsule. Each whitish seed has a small, fleshy tail (elaiosome) containing substances attractive to ants which distribute the seeds. The leaves die back a few weeks after the flowers have faded.
