Dissertation Research: Biosystematic Studies of the Penstemon kingii Group (Scrophulariaceae)

研究生卡尔·文森特，在 纽约植物园的诺埃尔霍姆格伦博士 纽约的花园与城市大学，计划一个全面的 形态学，染色体组成，黄酮类化合物 化学和授粉关系， 产于美国西部的一个属。 新 形态特征将使用扫描电子显微镜进行研究， 显微镜;这些字符将与化学集成 和染色体上的，以构建一个可靠的分类， 并决定进化关系。 领域 研究将测试特定的授粉 昆虫（蜜蜂，黄蜂和苍蝇）具有特殊的花型， 不同的物种。 该项目的成果将包括 改进了这些植物的分类，并深入了解了适应性 花形的演化

Graduate student Karl Vincent, under the supervision of faculty adviser Dr. Noel Holmgren of the New York Botanical Garden and City University of New York, plans a comprehensive study of the morphology, chromosome constitution, flavonoid chemistry, and pollination relationships of an estimated ten species of the genus Penstemon in western United States. New morphological features will be studied using scanning electron microscopy; these characters will be intergrated with chemical and chromosomal ones to construct a reliable classification of the group and determine evolutionary relationships. Field studies will test the association of particular pollinating insects (bees, wasps, and flies) with particular floral forms in the different species. Results of the project will include an improved taxonomy of these plants and insight into the adaptive evolution of floral form.
