PARSIMONY ANALYSIS OF CPDNA RESTRICTION SITE VARIATION IN SUBFAMILY NEPETOIDEAE (LABIATAE)

Parsimony analysis of cpDNA restriction site variation supports monoph yly of subfamily Nepetoideae, However, a close relationship among Nepe toideae and other gynobasic-styled Labiatae is not supported, indicati ng that a gynobasic style has evolved independently in at least two cl ades of Labiatae. The inferred relationships are congruent with the cl assification of Cantino, Harley, and Wagstaff (1992, Advances in labia te sciences, 27-37, Royal Botanic Gardens, Kew) but conflict to varyin g degrees with traditional classifications. Monophyly of four tribes o f Nepetoideae also is supported.
