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".
Melaleuca orbicularis Melaleuca orbicularis is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is similar to "Melaleuca cordata" with its pinkish "pom-pom" heads of flowers but its leaves are smaller, almost circular compared to the heart shaped leaves of the other species.
