Neowerdermannia
Neowerdermannia chilensis
Neowerdermannia is a genus of flowering plants of the cactus family ( Cactaceae ). The botanical name of the genus honors the German plant collector Erich Werdermann. The addition of " Neo " was necessary because the name was already assigned to Werdermannia a genus of cruciferous plants ( Brassicaceae).
Description
The individual, low-growing species of the genus Neowerdermannia are spherical to pressed spherical and have a strong taproot. Approximately 16 spiral ribs usually are hardly distinguishable as they are dissolved in warts. The areoles are often sunken and are located at the base of the top of the warts. From the arising therefrom some thorns are curved or hooked.
The funnel- shaped flowers are white to purple pink. They open on the day. Your flower cups and the short corolla tube are covered with fleshy scales and bare areolae.
The round, horizontal with a little top or side aufreißenden fruits contain broadly ovate roughened seeds.
Systematics and distribution
The genus Neowerdermannia is widespread in northern Argentina, southern Bolivia, Peru and northern Chile. The first description of the genus was made in 1930 by Alberto Vojtěch Fric.
The genus includes two species:
- Neowerdermannia chilensis Neowerdermannia chilensis subsp. chilensis
- Neowerdermannia chilensis subsp. peruviana
