Table 2 Morphological character states and additional subgeneric species-groups delineated for character reconstruction. Numbers in paraenthethes correspond to character designations from Cairns and Bayer [2]

From: A phylogenetic analysis of the Primnoidae (Anthozoa: Octocorallia: Calcaxonia) with analyses of character evolution and a key to the genera and subgenera
