Which has smaller flowers, Campsis or Kalmiopsis?
Kalmiopsis Kalmiopsis is a small genus of flowering plants in the heath family. It contains two vaginas, which are endemic to Oregon in the United States. This was a monotypic genus containing only "Kalmiopsis leachiana" until 2007, when a form of it was elevated to species status, "Kalmiopsis fragrans".
Corylopsis Corylopsis is a genus of nearly 30 species of shrubs in the witch hazel family, Hamamelidaceae, native to eastern Asia with the majority of species endemic in China but with some also in Japan, Korea, and the Himalayas. This genus is also known from the extinct species "Corylopsis reedae" described from Eocene leaf fossils found in Washington State, USA.
