Pollination by sexual deceit is well known in the orchid family. This unusual system has been studied in detail for many temperate, terrestrial orchid lineages, but rarely in the New World. In the Neotropical orchid genus Mormolyca, sexual deception has evolved along with food reward and food deception, thereby providing an opportunity to explore correlations between flower morphology and scent. This research incorporates techniques from multiple disciplines (molecular evolution, micro-morphology and chemical ecology) in an attempt to gain a holistic picture of evolutionary processes underlying lineage diversification of an orchid group with multiple pollination systems.Given that the Neotropics harbor an impressive number of orchid species, this integrated approach should be especially helpful in understanding this biodiversity hotspot. The research is helping to train a Ph.D. student in modern approaches to molecular systematics and chemical ecology. It will allow him to continue serving as a mentor to undergraduate students, and significantly enhance the impact his dissertation will have on the discipline. Not only scientific papers, but also products for a broader audience will be made available in orchid society publications and websites devoted to orchid enthusiasts. Educational activities focused on orchid pollination also will be developed based on the results for K?12 outreach events.

性欺骗的授粉在兰花家族中是众所周知的。对于许多温带陆地兰花谱系，已经对这种不寻常的系统进行了详细的研究，但在新世界很少。在新热带兰花属Mormolyca中，性欺骗随着食物奖励和食物欺骗的发展而演变，从而提供了探索花形态与气味之间相关性的机会。 This research incorporates techniques from multiple disciplines (molecular evolution, micro-morphology and chemical ecology) in an attempt to gain a holistic picture of evolutionary processes underlying lineage diversification of an orchid group with multiple pollination systems.Given that the Neotropics harbor an impressive number of orchid species, this integrated approach should be especially helpful in understanding this biodiversity hotspot.该研究正在帮助培训博士学位。分子系统学和化学生态学的现代方法中的学生。这将使他能够继续担任本科生的导师，并显着增强他的论文对学科的影响。不仅科学论文，而且还可以在兰花社会的出版物和专门针对兰花爱好者的网站上提供更广泛的受众的产品。 基于K？12外展活动的结果，还将开发针对兰花授粉的教育活动。
