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.

通过性欺骗授粉在兰科植物中是众所周知的。人们对许多温带陆生兰花谱系的这种不寻常的系统进行了详细研究，但在新世界却很少。在新热带兰花属 Mormolyca 中，性欺骗随着食物奖励和食物欺骗而进化，从而提供了探索花朵形态和气味之间相关性的机会。这项研究结合了多个学科（分子进化、微形态学和化学生态学）的技术，试图全面了解具有多种授粉系统的兰花类群谱系多样化的进化过程。兰花物种，这种综合方法应该特别有助于了解这一生物多样性热点。该研究正在帮助培养博士生。现代分子系统学和化学生态学方法的学生。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该学科的影响。兰花协会出版物和专门为兰花爱好者提供的网站不仅提供科学论文，还提供面向更广泛受众的产品。 还将根据 K-12 外展活动的结果开展以兰花授粉为重点的教育活动。
