Genus of flowering plants
Boea is a genus of plants in the family Gesneriaceae, with species originating from Australia, China, India, Malaysia, Myanmar, Philippines, Polynesia, Solomon Islands, Thailand, Papua New Guinea, Indonesia, Nepal, Bhutan, Cambodia, Vietnam and Laos.
For example, "B. hygroscopica", also known as the Queensland rock violet in Australia, occurs in Cape York Peninsula and Northeast Queensland as far south as Rockhampton, from elevation. It grows along creek beds, on moist banks, moss-covered rocks in rainforest, open forest, vine forest and gallery forest.
Some "Boea" species are known as types of resurrection plant due to their ability to survive desiccation (e.g. "B. hygrometrica" and "B. hygroscopica").
