Missing Sister Species (C. oreothauma)

C. siliqua was long thought to be the lone species in its genus. In the 1980s a sister species, C. oreothauma, was discovered. It is not included on this tree, but if it were, it would be in this spot, represented as another branch forming a clade with C. siliqua.
