"A few bog orchids are listed under the Massachusetts Endangered Species Act. Listed plants include the pale green orchid (P. flava var. herbiola), leafy white orchid (P. dilatata), crested fringed orchid (P. cristata), and orange-fringed orchid (P. ciliaris), which hasn’t been observed since the 1970s and is now considered extirpated from the state."
