Not quite newly discovered. The plant, camellia ptilophylla, has been studied for at least a couple of decades, e.g. see [1] [2]: Cocoa tea (Camellia ptilophylla), which belongs to the genus Camellia, is a naturally decaffeinated tea plant. For many years, it has been widely consumed by local inhabitants in the Longmen area of Guangdong Province of China but has only started attracting scientific interest since 1988. The tea is also called cocoa tea for the presence of theobromine, the same stuff you find in chocolate, about 10% by weight compared to about 0.35% in green tea.
