Abstract

Abstract The Neotropical genus Pentacalia Cass. (Compositae, Senecioneae) is distributed from southern Mexico to northwestern Argentina, plus two disjunct species that thrive in Brazil. Most species diversity occurs in the montane forests of Colombia, Ecuador, and Peru. It comprises scandent woody plants characterized by displaying alternate leaves (opposite in three species), involucres with supplementary bracts, usually yellow ray florets (when present), sagittate to caudate anther bases, and truncate to obtuse style branches with a crown of sweeping trichomes (sometimes with a tuft of longer trichomes, but not strictly penicillate). The Bolivian species were revised for the first time by Cabrera (1985), who treated the group under Senecio L. sect. Streptothamni Greenm. Because of the subsequent addition of new species and the need of taxonomic arrangements, an updated synopsis of the genus recognizing 18 species is presented. The names P. brittoniana (Hieron.) Cuatrec. and P. miguelii (Cuatrec.) Cuatrec. are synonymized with P. psidiifolia (Rusby) Cuatrec., as well as P. inquisiviensis H. Rob. & Cuatrec. with P. cardenasii (Cuatrec.) Cuatrec. and P. sailapatensis (Cuatrec.) Cuatrec. with P. urubambensis (Cabrera) Cuatrec. Seven names are lectotypified and an epitype is designated for the name P. zongoensis (Cabrera) J. Calvo. The new species P. viburnifolia J. Calvo & A. Fuentes is described. Revised nomenclature, succinct descriptions, taxonomic discussions, lists of specimens examined, and distribution maps are provided for all accepted species, in addition to an identification key. Pictures of living plants are also presented for eight species.

玻利维亚五花属（菊科、千里光科）简介

摘要新热带五花属。（菊科，千里光科）分布于墨西哥南部至阿根廷西北部，另外还有两个在巴西生长的间断物种。大多数物种多样性发生在哥伦比亚、厄瓜多尔和秘鲁的山地森林中。它包括攀缘木本植物，其特征是呈现互生叶（三种相反），总苞片具补充苞片，通常为黄色射线小花（当存在时），箭头状至尾状花药基部，截形至钝型分枝，顶端有横扫毛状体（有时有一簇较长的毛状体，但不是严格的青霉状）。Cabrera（1985）首次对玻利维亚物种进行了修订，他将该物种归入Senecio L.教派。Streptothamni Greenm。由于随后增加了新的物种和分类安排的需要，提出了一个识别18个物种的属的更新概要。名称P.brittoniana（Hieron.）Cuatrec。和P.miguelii（Cuatrec.）Cuatrec。与P.psidiifolia（Rusby）Cuatrec同义。，以及P.inquisiviensis H.Rob。&Cuatrec。与P.cardenasii（Cuatrec.）Cuatrec。和P.sailapantensis（Cuatrec.）Cuatrec。与P.urubambensis（Cabrera）Cuatrec。对七个名称进行了分类，并为P.zongoensis（Cabrera）J.Calvo名称指定了一个表型。本文报道了一个新的物种P.viburnifolia J.Calvo和A.Fuentes。除了一个识别钥匙外，还提供了所有接受物种的修订命名法、简洁描述、分类学讨论、检查标本清单和分布图。还展示了八个物种的活体植物图片。

期刊介绍： The Annals of the Missouri Botanical Garden is a quarterly international journal primarily devoted to systematic botany and evolutionary biology. We encourage submissions of original papers dealing with significant advances in the taxonomy, phylogeny, biogeography, paleobiology, and evolution of plants, and in conservation genetics and biology, restoration ecology, and ethnobiology, using morphological and/or molecular characters, field observations, and/or database information. We also welcome reviews and papers on conceptual issues and new methodologies in systematics. Important floristic works will also be considered. Symposium proceedings discussing a broader range of topical biological subjects are also published, typically once a year. All manuscripts are peer-reviewed by qualified and independent reviewers.
