Abstract
Although the Orchidaceae are one of the two largest families of angiosperms, they have been neglected as subjects for evolutionary studies by most plant systematists. This omission is surprising for two reasons: the family exhibits considerable heterogeneity and available evidence supports the hypothesis that it has been evolutionarily active (Dressler, 1981). To a large extent, the tropical distribution of orchids and their complex floral morphology have been historically responsible for dulling the interest of potential students (for example, considerably greater numbers of systematists have focused on the Asteraceae and Fabaceae). Nevertheless, interest in evolutionary issues concerning orchids has recently increased (Ackerman, 1986, Ackerman, 1989; Benzing, 1987; Dafni, 1987). Molecular systematics is likely to have a major impact on such studies in the future, and it is in this light that the following study on the orchid subtribe Oncidiinae is presented.
