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.

"H. barkerae" is found in the Western Cape from the Bokkeveld Mountains near Nieuwoudtville and the foothills of the Roggeveld Mountains, to the Hantamsberg near Calvinia, and bounded to the north and south by Loeriesfontein and the Tanqua Karoo.
