Conradina brevifolia

Conradina brevifolia is a rare species of shrub in the mint family known by the common name short-leaved false rosemary. It is endemic to Central Florida, where it is known only from the Lake Wales Ridge. There are perhaps 36 occurrences of the plant remaining, and 10 of these are likely to be destroyed as their habitat is fragmented in the coming years. About 15% of the Lake Wales Ridge, the only home territory of the plant, remains today, the rest having been cleared for development and citrus groves. Few of the extant populations have more than 25 plants. This is a federally listed endangered species of the United States....read more on Wikipedia.
