Foonchewia coriacea , a new combination to replace F. guangdongensis (Rubiaceae)

Examination of both specimens and literature has shown that Mycetia coriacea (based on Adenosacme coriacea ; Rubiaceae) has apically dehiscent dry capsules, quite different from the indehiscent berries of other species of the genus Mycetia . In various characters including the fruits, the species is found to be identical with the newly described species Foonchewia guangdongensis , the only species of the genus Foonchewia and the tribe Foonchewieae. Therefore, the new combination Foonchewia coriacea is here proposed to replace F. guangdongensis .
