Amaryllis

Amaryllis () is the only genus in the subtribe Amaryllidinae (tribe Amaryllideae). It is a small genus of flowering bulbs, with two species. The better known of the two, "Amaryllis belladonna", is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley to Knysna. For many years there was confusion among botanists over the generic names "Amaryllis" and "Hippeastrum", one result of which is that the common name "amaryllis" is mainly used for cultivars of the genus "Hippeastrum", widely sold in the winter months for their ability to bloom indoors. Plants of the genus "Amaryllis" are known as belladonna lily, Jersey lily, naked lady, amarillo, Easter lily in Southern Australia or, in South Africa, March lily due to its propensity to flower around March. This is one of numerous genera with the common name "lily" due to their flower shape and growth habit. However, they are only distantly related to the true lily, "Lilium". In the Victorian Language of Flowers (see Plant symbolism), amaryllis means "pride".

"Amaryllis" is a bulbous plant, with each bulb being in diameter. It has several strap-shaped, green leaves, long and broad, arranged in two rows.

Each bulb produces one or two leafless stems 30–60 cm tall, each of which bears a cluster of two to twelve funnel-shaped flowers at their tops. Each flower is diameter with six tepals (three outer sepals, three inner petals, with similar appearance to each other). The usual color is white with crimson veins, but pink or purple also occur naturally.

The single genus in subtribe Amaryllidinae, in the Amaryllideae tribe. The taxonomy of the genus has been controversial. In 1753 Carl Linnaeus created the name "Amaryllis belladonna", the type species of the genus "Amaryllis". At the time both South African and South American plants were placed in the same genus; subseq...
