Disterigma, a genus of Neotropical blueberries, grows in the threatened northern Andean cloud forests. Morphological and molecular studies will be conducted to understand the characteristics, diversity, habitat, and endemism of the various species. Specimens from major European herbaria will be examined and new observations and analyses will be made from samples collected from the field. The project will conclude with a published revision of Disterigma for the Neotropics.This is the first systematic revision of a genus in the Blueberry Family (Ericaceae) from the Neotropics that combines traditional morphology and modern molecular analysis. Data from this study will provide a framework for testing hypotheses of speciation and biogeography in Andean plants. The revision will contain descriptions, keys, illustrations, distribution maps, and illustrations needed to identify species. It will also provide information about the habitat, conservation status, and uses of Disterigma. This aspect of the work is essential for the assessment and conservation of the thirteen species that are threatened and the twenty that have restricted distributions. This study will help to justify the protection of areas that are undergoing change from increased human occupation. Results will raise public awareness about Andean biodiversity and the urgent need to preserve it.

Disterigma 是新热带蓝莓属，生长在受威胁的安第斯山脉北部云雾森林中。将进行形态学和分子研究，以了解不同物种的特征、多样性、栖息地和特有现象。将检查来自欧洲主要植物标本馆的标本，并对从现场采集的样本进行新的观察和分析。该项目将以已发布的新热带地区 Disterigma 修订版结束。这是对新热带地区蓝莓科（杜鹃花科）属的首次系统修订，结合了传统形态学和现代分子分析。这项研究的数据将为检验安第斯植物物种形成和生物地理学的假设提供一个框架。修订版将包含描述、索引、插图、分布图和识别物种所需的插图。它还将提供有关 Disterigma 的栖息地、保护状况和用途的信息。这方面的工作对于评估和保护 13 种受到威胁的物种和 20 种分布受限的物种至关重要。这项研究将有助于证明对因人类占领增加而发生变化的地区进行保护的合理性。结果将提高公众对安第斯生物多样性和保护它的迫切需要的认识。
