Delissea argutidentata

Delissea argutidentata is a rare species of flowering plant in the bellflower family, Campanulaceae. It is part of the Hawaiian lobelioid group, which is known for its unique evolutionary radiation throughout the Hawaiian Islands. The species is endemic to Hawaiʻi Island and is considered critically endangered. For many years, Delissea argutidentata was believed to be extinct in the wild, but a small wild population was rediscovered in 2021 in a remote area of Hawai'i Island. Its rediscovery is important because many Hawaiian plants have declined due to habitat loss, invasive species, and changes to native forest ecosystems....read more on Wikipedia.
