In the plant tree of life, a group of plants of special interest are the cycads. The cycads are widely considered the world’s most endangered plants with most of the 380 living species considered threatened by extinction according to the International Union for the Conservation of Nature’s Red List of Threatened Species. These early plants are often termed living fossils because of their ancient origin over 300 million years ago and their prevalence during the age of the dinosaurs, a time in which they were much more widespread and diverse than they are today. The surviving cycads are particularly valuable for studying plant evolution because of their excellent fossil record. Even though they have changed little in outward appearance, these plants have many unique features, some of which are ancestral (primitive) and some of which are derived (advanced). To save them from extinction, we need to understand when those changes occurred through time and correlate them with environmental changes and other biotic factors. Furthermore, the chemistry of modern cycads is unique and has significant implications for human health, particularly in neurobiology. In a way, cycads serve as a Rosetta stone for plant evolution. This project will synthesize all available data on cycad biology and make those data accessible, via a web site, to a broad audience of researchers as well as to the community of people who are interested in and able to contribute significantly to cycad conservation efforts. This project will generate a complete, modern e-monograph and data repository of the Cycads. Many avenues of research will be opened in the areas of taxonomy, biogeography, genomics, and evolutionary biology. This e-monograph, hosted by The World List of Cycads, will serve to provide the resources, background, and basics for those pursuits. It will include original species descriptions, type specimens, synonyms, invalid and illegitimate nomenclature, and all published nomenclature at various taxonomic levels. There will be modern, parallel descriptions of all taxa accompanied by photographs and line art, as well as identification tools, distribution maps, habitat data with historic and contemporary photographs, ecology, structural data, chemical data, life cycle information, and phenology and pollination biology when known. The e-monograph will also include an illustrated glossary and sections on ethnobotany, vernacular names, phytochemistry, growth and development, and nitrogen fixation. The comprehensive synthesis undertaken here will benefit from the digitization of over 5000 historic and contemporary microscope slides made by C.J. Chamberlain on embryology and by Adriance Foster, Marion Johnson, and Knut Norstog on developmental anatomy and morphology. Relevant sections tied to black and white images published by these researchers, as well as those of PI Stevenson, will be digitized in color and incorporated into developmental pages, thereby providing more detailed information on cycad structure to the research community. Historic habitat photographs of cycads by Chamberlain, Norstog, and Stevenson will be scanned and added to the species descriptions and the geography and ecology sections.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在植物生命树中，有一组特别有趣的植物是苏铁。苏铁被广泛认为是世界上最濒危的植物，根据国际自然保护联盟的濒危物种红色名录，380种现存物种中的大多数被认为受到灭绝的威胁。这些早期的植物通常被称为活化石，因为它们起源于3亿多年前，而且它们在恐龙时代的流行，在那个时代，它们比今天更广泛和多样化。幸存下来的苏铁由于其出色的化石记录，对于研究植物进化特别有价值。尽管它们在外观上变化不大，但这些植物有许多独特的特征，有些是祖先的(原始的)，有些是衍生的(高级的)。为了使它们免于灭绝，我们需要了解这些变化是在何时发生的，并将它们与环境变化和其他生物因素联系起来。此外，现代苏铁的化学成分是独一无二的，对人类健康有重大影响，特别是在神经生物学方面。在某种程度上，苏铁是植物进化的罗塞塔之石。该项目将综合关于苏铁生物学的所有现有数据，并通过网站向广大研究人员以及对苏铁保护工作感兴趣并能够做出重大贡献的社区提供这些数据。该项目将生成一本完整的、现代化的苏铁电子专著和数据库。将在分类学、生物地理学、基因组学和进化生物学领域开辟许多研究途径。这本由世界苏铁名录主办的电子专著，将为这些追求提供资源、背景和基础。它将包括原始的物种描述、模式标本、同义词、无效和不合法的命名，以及在不同分类水平上发布的所有命名。将有对所有分类群的现代平行描述，并附有照片和线条艺术，以及识别工具、分布图、带有历史和当代照片的栖息地数据、生态学、结构数据、化学数据、生命周期信息，以及已知的物候和授粉生物学。电子专著还将包括一个图文并茂的词汇表和关于民族植物学、方言名称、植物化学、生长发育和固氮的章节。这里进行的全面合成将受益于C.J.张伯伦关于胚胎学以及阿德里安斯·福斯特、马里恩·约翰逊和克努特·诺斯托格关于发育解剖学和形态学的5000多张历史和当代显微镜幻灯片的数字化。与这些研究人员发表的黑白图像相关的部分，以及Pi Stevenson的部分，将以彩色数字化并纳入开发页面，从而向研究界提供更详细的苏铁结构信息。张伯伦、诺斯托格和史蒂文森拍摄的苏铁历史栖息地照片将被扫描并添加到物种描述以及地理和生态部分。这一奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
