Under the direction of faculty adviser Dr. Schilling, graduate student Mr. Panero will conduct field work in several countries of Andean South America, collecting samples of ca. 25 species of the sunflower group Helianthopsis. To improve our ability to recognize species in this genus and to construct an hypothesis about evolutionary relationships among the species and their closest generic relatives, Mr. Panero will study traditional morphological characters and will add new evidence derived from chromosome analysis, electron-microscopy of floral features, and biochemical study of flavonoids. Mr. Panero has conducted field work in the tropics in the past, and has planned an effective program of sampling and analysis to complete a modern taxonomic revision of this group of poorly known tropical plants. Dr. Schilling is an expert on the taxonomy and evolution of the sunflower family of plants.

在指导老师Schilling博士的指导下，研究生Panero先生将在南美洲安第斯山脉的几个国家进行实地考察，收集向日葵群中大约25种向日葵的样本。为了提高我们识别该属物种的能力，并构建物种及其最接近的属间进化关系的假设，Panero先生将研究传统的形态特征，并将从染色体分析、花特征的电子显微镜和类黄酮的生化研究中添加新的证据。帕内罗先生过去曾在热带地区进行过实地考察，并计划了一个有效的采样和分析计划，以完成对这组鲜为人知的热带植物的现代分类修订。席林博士是向日葵科植物分类学和进化方面的专家。
