摘要

本报告描述了巴西东北部巴伊亚州大西洋森林山地湿地森林中的一种新的喜树属植物（Bombacoideae，锦葵科），并绘制了图解。目前仅从海拔 750 米至 850 米的山顶上的三个种群中得知该植物，根据世界自然保护联盟的标准，该植物被列为濒危物种（EN）。Eriothecapaganuccii 与所有同属植物的不同之处在于，它的叶片呈鸡冠状或强鸡冠状，种子极少，球形或近球形木质蒴果，内含稀少的木棉花，是迄今所知本属植物中最大的种子。本文讨论了 E.paganuccii与形态相似物种的亲缘关系，以及获得完整物候采集的重要性。

Eriothecapaganuccii (Bombacoideae, Malvaceae), a new endangered species from montane forests in the Atlantic Forest of Bahia, northeastern Brazil.

A new species of Eriotheca (Bombacoideae, Malvaceae) from montane wet forests in the Atlantic Forest of Bahia, northeastern Brazil, is described and illustrated. It is known from only three populations situated between 750 m and 850 m in elevation on mountain summits and categorized as Endangered (EN) based on IUCN criteria. Eriothecapaganuccii is distinct from all congeners by the combination of coriaceous to strongly coriaceous leaves and remarkable few-seeded, globose to subglobose woody capsules that contain scanty kapok and the largest seeds known in the genus to date. The affinities of E.paganuccii to morphologically similar species as well as the importance of obtaining phenologically complete collections are discussed.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
