Rediscovery of the lost little dogwood Cornus wardiana (Cornaceae)—Its phylogenetic and morphological distinction and implication in the origin of the Arctic-Sino-Himalayan disjunction
The dwarf dogwoods (subgenus Arctocrania) have been widely known to consist of three circumboreal species Cornus suecica, Cornus canadensis, and Cornus unalaschkensis. A fourth putative species was discovered from the northern Myanmar in 1937, but it had never been formally reported on. Here, we formally report the species on the basis of phylogenetic and morphological evidence and name it Cornus
