Which genus has more species, Wahlenbergia or Horminum?
Wahlenbergia Wahlenbergia is a genus of between 150–270 species of flowering plants in the family Campanulaceae, with a cosmopolitan distribution except for North America; the highest species diversity is in Africa and Australasia. "Wahlenbergia" species have dispersed widely, even to oceanic islands, and there are four species known from the island of Saint Helena, including the now extinct species "W. roxburghii". The genus was named after Göran Wahlenberg (a Swedish botanist who taught at Uppsala University) by German botanist H. A. Schrader (Heinrich Schrader), in 1814.
Pinguicula alpina Pinguicula alpina, also known as the alpine butterwort, is species of carnivorous plant native to high latitudes and altitudes throughout Eurasia. It is one of the most widespread "Pinguicula" species, being found in mountainous regions from Iceland to the Himalayas. Native to cold climates, it is a temperate species, forming prostrate rosettes of green to red leaves and white flowers in the summer and a tight hibernaculum during a period of winter dormancy in the winter. Like all members of the genus, "P. alpina" uses mucilagenous glands covering the surface of its summer leaves to attract, trap, and digest arthropod prey.
