The sprekelia ( Sprekelia ) are a genus in the subfamily Amaryllidoideae within the family of the Amaryllis (Amaryllidaceae). The roughly two types are common in Mexico . Since the shape of the flower is reminiscent of the cross of the Knights of St. Jacob , trivial names such as Jacob's lily have become common in various languages .
Sprekelia formosissima
Sprekelia formosissima is said to be the most beautiful of all the species that used to be considered amaryllis .
description
The structure of the Sprekelia formosissima is similar to the knight's stars , although it only reaches heights of about 30 centimeters and is therefore a lot smaller. The sword-shaped, basal leaves are much more delicate. In contrast to Hippeastrum , the reddish, hollow inflorescence stem only has a cross-like, carmine-red flower that develops from a rather long onion neck. The onion itself is round, almost the size of a hyacinth onion, and wrapped in a dark brown onion cover.
Culture conditions
During the growing season in spring, one or more inflorescences develop from the small onion of Sprekelia formosissima . But only one of them comes to bloom. The leaves only start to grow properly after the flowering period. After the vegetation phase, the leaves are drawn in and the onion should spend the winter in a cool place, because it is not hardy with us. Since it does not endure severe impairment during the rest period, this plant species is almost always kept in pots in Europe.
Systematics
The genus Sprekelia was established in 1755 by Lorenz Heister in Description of a New Sex , 15, 19. The generic name Sprekelia honors Johann Heinrich von Spreckelsen (1691–1764), who sent the first Sprekelia copies to Lorenz Heister.
The genus Sprekelia belongs to the tribe Hippeastreae in the subfamily Amaryllidoideae within the family of Amaryllidaceae . It used to be part of the Liliaceae family. Other authors place this genus in the Alliaceae family . The genera Sprekelia and Hippeastrum are closely related, just like these they were previously assigned to the genus Amaryllis . Thus, the best-known species, Sprekelia formosissima , can still be found in the older specialist literature with the old name Amaryllis formosissima .
There are about two types of Sprekelia :
- Sprekelia formosissima (L.) Herb. (Syn .: Hippeastrum formosissimum (L.) Loudon , Amaryllis formosa Salisb. , Amaryllis karwinskii Zucc. , Sprekelia glauca Lindl. , Sprekelia stenopetala Lem. , Sprekelia ringens C.Morren , Sprekelia karwinskii (Zucc.) M.Roem. , Sprekelia heisteri Trew ex Kunth , Sprekelia clintiae Traub ): It is the type species in Lorenz Heister : Description of a new sex , published 1755, 15, 19; its basionyma is Amaryllis formosissima L. It is common in Mexico.
- Sprekelia howardii Lehmiller : This species was mentioned in 2000 in David J. Lehmiller: A New Species of Sprekelia (Amaryllidaceae). First describedin: Herbertia , 1999, 54, pp. 228-231. It occurs only in southern Mexico. It is much smaller than Sprekelia formosissima and the bracts and foliage are also narrower. It occurs only in the Mexican state of Guerrero .
The relationship between Sprekelia and Hippeastrum is so close that hybrids are sometimes possible.
