A genus of two species, natives one of N. America the other of Japan, allied to Vaccinium and Gaylussacia.
From the Supplement (Vol. V)
Although this genus has been grouped with Vaccinium and Gaylussacia by some botanists, its affinity is really with Gaultheria, in which it is now usually included. Both the species mentioned have valid alternative names in that genus – C. hispidula as G. hispidula (L.) Muhl. and its Japanese ally as G. japonica (Gray) Sleum.
