摘要

新种 Oritrophium acerosum（菊科，Astereae）产于厄瓜多尔南部阿苏艾省和莫罗纳-圣地亚哥省交界处的帕托科查山麓。除其他特征外，该物种的特点是体型较小，莲座丛由 20-35 片叶组成，比花葶短得多，叶呈线形，强烈外卷，正面无毛，假叶柄长于叶片。本报告提供了类似物种的分类讨论，以及活体植物的详细图片和厄瓜多尔境内该属物种的二分法检索表。

A new species of Oritrophium (Compositae, Astereae) from the páramo of Ecuador

The new species Oritrophium acerosum (Compositae, Astereae) is described from the páramo de Patococha at the border between the provinces of Azuay and Morona-Santiago, southern Ecuador. Among other features, the species is characterized by its reduced size, rosettes composed of 20–35 leaves much shorter than the scape, and linear, strongly revolute leaves with a glabrous adaxial surface, and pseudopetioles longer than the lamina. A taxonomic discussion of similar species is provided, as well as detailed pictures of living plants and a dichotomous key to the species of the genus in Ecuador.

期刊介绍： Since 1931, Brittonia, assuming the broadest possible definition of the field of systematic botany, has been an important outlet for the publication of original research articles on anatomy, botanical history, chemotaxonomy, morphology, paleobotany, phylogenetic systematics, taxonomy, and phytogeography. Each issue contains articles by the staff of The New York Botanical Garden and outside contributors, book reviews, and announcements.
