Abstract. Neea gustaviaefolia, a new species from the wet forests from “Sierra de La Macarena” and upper “Guaviare” river regions of Colombia (Guaviare and Meta departments) is described, illustrated, and its morphological relationships are discussed. This new species is a small tree of 6 m tall, on the basis of its alternate, oblanceolate larger leaves and a shorter terminal cymes inflorescence, verticillate (with three opposite primary branches), it does not appear to be closely allied to any other Neea species. This new species shares several other features with five species (N. alumnorum, N. brevipedunculata, N. floribunda, N. itanhaensis and N. verticillata). Morphologically, however, it is comparable to N. alumnorum and N. itanhaensis but it differs in its leaves, inflorescences, staminal perianth, and stamens number. In addition, ecological, floristic, and geological notes about the “La Sierra de La Macarena are included. A key for identifying species of Neea to Colombia is also provided. Neea gustaviaefolia is remarkable for its alternate, larges leaves (30–65 × 10–20 cm), in an otherwise predominantly opposite, small to medium (4–25 × 2–8 cm) leaved genus, and it increases to 27 the number of species of the genus to Colombia flora.
摘要本文描述了哥伦比亚“Sierra de La Macarena”和“Guaviare”河上游地区(Guaviare和Meta省)湿林的新种Neea gustaviaefolia,并对其形态关系进行了讨论。这个新物种是一棵6米高的小树,基于它的互生,倒披针形的大叶子和一个较短的聚伞花序的末端花序,轮生(有三个相对的主枝),它似乎与任何其他Neea物种没有密切的联系。该新种与其他5种(N. alumnorum, N. brevipedunculata, N. floribunda, N. itanhaensis和N. verticillata)具有相同的特征。在形态上,它与N. alumnorum和N. itanhaensis具有可比性,但在叶片、花序、雄蕊花被和雄蕊数上存在差异。此外,还包括了关于“La Sierra de La Macarena”的生态、植物和地质笔记。本文还提供了鉴定哥伦比亚楝属植物种类的钥匙。Neea gustaviaefolia以其互生的大叶子(30-65 × 10-20厘米)而闻名,在其他方面主要是对生的,小到中叶(4-25 × 2-8厘米),它在哥伦比亚的植物区系中增加到27种。

Abstract. Maytenus species bearing fruits with a coriaceous pericarp that open by two valves and having seeds that are completely covered by a white aril are currently placed in the genus Monteverdia. One hundred and twenty-three combinations have been proposed following these two diagnostic characters. However, according to Art. 41.5 of the International Code of Nomenclature for algae, fungi and plants, one of these combinations has not been validly published. The validation of the combination Monteverdia psammophila is provided here through the presentation of the complete citation of its basionym.
摘要Maytenus种的果实具有由两个瓣叶打开的皮质果皮,种子完全被白色假种皮覆盖,目前被归入Monteverdia属。根据这两个诊断特征,已经提出了123种组合。然而,根据《藻类、真菌和植物国际命名法》第41.5条,其中一种组合尚未有效发表。本文通过对其基本原理的完整引用,对蒙氏菌组合进行了验证。

Abstract. Barra Honda National Park (BHNP) lies in the Tempisque River Basin of the Península de Nicoya, Guanacaste, Costa Rica. The Park is well known for its limestone caverns, which date from the Upper Paleocene–Lower Eocene and are the main attraction of BHNP. The area shows a marked climatic seasonality with a predominantly semideciduous tropical dry forest. We present a floristic treatment of the orchids of BHNP based on field collections, herbarium sampling, and documentation of living specimens. We discuss the biodiversity, climate, geology, and topography of the Park and provide a novel vegetation zones map with eight floristic associations: bean plantations, disturbed secondary forest, evergreen forest, jaragua fields, mature secondary forests, pastures, rocky areas, karstic limestone pavement, and young secondary forest. For the 36 species belonging to 29 genera recorded, we provide composite line drawings and Lankester composite digital plates, descriptions, distribution, ecology, etymology, synonymy, taxonomy, photographs, and a key to the species for field identification based on morphology. Ten species of orchids (27.8%) are terrestrials and 26 are epiphytes (72.2%). The evergreen forest contains 80% of the orchid species of BHNP. We describe Pelexia barrahondaensis and Sarcoglottis calcicola as new to science, and we propose a new combination under Specklinia for Pleurothallis panamensis. Also, we record the terrestrial orchid genus Tropidia for the first time in Costa Rica. The present study provides new information on the Nicoya Peninsula's dry forest ecosystems for in situ conservation and research. This work can be useful for other protected areas within the same ecosystem that lack a floristic treatment of the Orchidaceae.
摘要巴拉本田国家公园(BHNP)位于哥斯达黎加瓜纳卡斯特Península de Nicoya的Tempisque河流域。公园以其石灰岩洞穴而闻名,这些洞穴可以追溯到上古新世-下始新世,是BHNP的主要景点。该地区气候季节性明显,以半落叶热带干燥林为主。我们在野外采集、植物标本室取样和活标本记录的基础上,对BHNP的兰花进行了植物区系分析。我们讨论了公园的生物多样性、气候、地质和地形,并提供了一个新的植被带地图,其中包含八个植物区系:豆类种植园、干扰次生林、常绿林、jaragua田、成熟次生林、牧场、岩石区、岩溶石灰岩路面和年轻次生林。对已记录的29属36个种,我们提供了复合线图和Lankester复合数字板、描述、分布、生态、词源、同义、分类、照片,并提供了一种基于形态学的野外鉴定钥匙。陆生兰花10种(27.8%),附生兰花26种(72.2%)。这片常绿森林包含了BHNP 80%的兰花种类。我们将Pelexia barrahondaensis和Sarcoglottis calcicola描述为科学上的新物种,并提出了Pleurothallis panamensis在Specklinia下的新组合。此外,我们还首次在哥斯达黎加记录了陆地兰花属Tropidia。本研究为尼科亚半岛干林生态系统的原位保护和研究提供了新的信息。这项工作可以为同一生态系统中缺乏兰科植物区系处理的其他保护区提供帮助。

Abstract. In this work a taxonomic revision is made of the nomenclature, distribution, and conservation status for the 84 species in the Colombian clade of Espeletia. Taxonomic changes include five new combinations for taxa at the species level that are transferred to Espeletia. Seventy-three species are endemic to the Colombian Cordillera Oriental (including four extending into the Venezuelan side of Páramo de Tamá), six are found in the Colombian Cordillera Central (four endemic to this range, one extending into Ecuador, and one shared with the Colombian Cordillera Occidental), three are endemic to the Colombian Cordillera Occidental, and two are endemic to Sierra de Perijá (including one yet to be found within Colombian borders). Geographic distributions at the páramo massif level are given for all species and subspecies. The IUCN Red List category is listed for each species, with suggestions for recategorization of some species with small distribution areas, low number of populations, and threats to their habitat extent and quality. In all, about 60 species in the Colombian Espeletia clade must be classified within a threatened category. When species belonging to the Venezuelan Espeletia clade that are found within Colombian borders are included, the current estimate of total diversity of Espeletia in this country is 90 species.
摘要在这项工作中,对哥伦比亚Espeletia分支中84个物种的命名、分布和保护状况进行了分类修订。分类学的变化包括五个新的物种级分类群组合,这些组合被转移到Espeletia。73种为哥伦比亚科迪勒拉东方特有种(包括4种延伸到Páramo de Tamá的委内瑞拉一侧),6种在哥伦比亚科迪勒拉中部发现(4种为该地区特有种,1种延伸到厄瓜多尔,1种与哥伦比亚科迪列拉西部共有),3种为哥伦比亚科迪勒拉西部特有种,其中两种是Sierra de Perijá的特有种(其中一种尚未在哥伦比亚境内发现)。给出了所有物种和亚种在páramo地块水平上的地理分布。国际自然保护联盟红色名录为每个物种列出了类别,并建议对一些分布面积小、种群数量少、栖息地范围和质量受到威胁的物种进行重新分类。总的来说,哥伦比亚Espeletia分支中大约有60个物种必须被归类为濒危物种。如果将哥伦比亚境内发现的属于委内瑞拉Espeletia分支的物种包括在内,目前估计该国Espeleta的总多样性为90种。

Abstract. We discuss a group of Pleurothallis species mostly characterized by plants relatively tall for the genus, with stems more than 20 cm long and fasciculate inflorescences produced above the leaf from a spathaceous, sometimes erect bract. We recognize 26 species and 4 natural hybrids in Costa Rica in this group of Pleurothallis, belonging to 4 informal assemblages of species, each one characterized by a unique set of vegetative, floral, and ecological features. This group, as well as its component units, is discussed as to its salient characteristics and internal relationships, underlying possible evolutionary trends. Diversity, general and floral ecology, color dimorphism, and natural hybridization are examined to address their systematic significance. We present a dichotomic key to the groups and the species discussed in this study, together with descriptions based on Costa Rican materials, and one or more line drawings or a Lankester Composite Dissection Plate when required for improved clarity. Also, we discuss their taxonomy and provide information on etymology, habitat, distribution, distinguishing features, and Costa Rican collections. Three species (P. callosa, P. longipetala, and P. mesopotamica), and three nothospecies (P. ×karremansiana, P. ×subversa, and P. ×parentis-certa) are described as new to science, discussed as to their affinities, and illustrated with photographs, composite digital plates, and ink drawings. Pleurothallis triangulabia is removed from the synonymy of P. phyllocardia, treated as a distinct species, and lectotypified. Pleurothallis anthurioides and P. maduroi are first recorded and documented for the flora of Costa Rica.
摘要我们讨论了一组Pleurothallis物种,其主要特征是该属植物相对较高,茎长超过20厘米,在叶片上方由匙形,有时直立的苞片形成束状花序。我们在哥斯达黎加的这组Pleurothallis中识别出26个物种和4个自然杂交种,属于4个非正式的物种组合,每个物种都具有独特的营养、花卉和生态特征。讨论了这个群体及其组成单元的显著特征和内部关系,以及潜在的进化趋势。多样性、一般和花生态学、颜色二态性和自然杂交被检验以解决它们的系统意义。我们为本研究中讨论的群体和物种提供了一个二分法键,以及基于哥斯达黎加材料的描述,以及一个或多个线条图或Lankester复合解剖板(当需要提高清晰度时)。此外,我们还讨论了它们的分类,并提供了有关词源、栖息地、分布、特征和哥斯达黎加收藏的信息。三个物种(P.callosa、P.longipetala和P.mesotamica)和三个新物种(P.×karremansiana、P.×subversa和P.×parentis certa)被描述为科学上的新物种,讨论了它们的亲缘关系,并用照片、复合数字板和水墨画进行了说明。三角胸膜菌是从叶心假单胞菌的同义词中删除的,被视为一个独特的物种,并被重新分类。在哥斯达黎加的植物区系中,首次记录和记录了拟花侧耳和拟花侧耳。

We recognize 26 species and 4 natural hybrids in Costa Rica in this group of Pleurothallis, belonging to 4 informal assemblages of species, each one characterized by a unique set of vegetative, floral, and ecological features. This group, as well as its component units, is discussed as to its salient characteristics and internal relationships, underlying possible evolutionary trends. Diversity, general and floral ecology, color dimorphism, and natural hybridization are examined to address their systematic significance. We present a dichotomic key to the groups and the species discussed in this study, together with descriptions based on Costa Rican materials, and one or more line drawings or a Lankester Composite Dissection Plate when required for improved clarity. Also, we discuss their taxonomy and provide information on etymology, habitat, distribution, distinguishing features, and Costa Rican collections. Three species (P. callosa, P. longipetala, and P. mesopotamica), and three nothospecies (P. ×karremansiana, P. ×subversa, and P. ×parentis-certa) are described as new to science, discussed as to their affinities, and illustrated with photographs, composite digital plates, and ink drawings. Pleurothallis triangulabia is removed from the synonymy of P. phyllocardia, treated as a distinct species, and lectotypified. Pleurothallis anthurioides and P. maduroi are first recorded and documented for the flora of Costa Rica.","PeriodicalId":39248,"journal":{"name":"Harvard Papers in Botany","volume":"26 1","pages":"203 - 295"},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45554594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract. Four new arctic species of Draba are described here. Of these, D. airdii, D. shehbazii, and D. darbyshireii are from Canada, and D. catlingii is from both Canada and Alaska. Two new species described by others, D. adamsii and D. macrocarpa, are also added. The chromosome numbers n = 19 and 2n = 36 should be attributed to D. grandis, and n = 8 for D. lonchocarpa var. kamtschatica to D. chamissonis. Draba kluanei is now known to occur at a second location in Yukon. The six new Draba species added in this study bring the total number in Canada and Alaska to 65. A key to all of these species is presented.
摘要这里描述了四种新的北极德拉巴。其中,D. airdii, D. shehbazii和D. darbyshireii来自加拿大,D. catlingii来自加拿大和阿拉斯加。另外还增加了另外两种新种D. adamsii和D. macrocarpa。染色体数n = 19和2n = 36属于大田鼠,染色体数n = 8属于香田鼠。现在已知的是,德拉巴kluanei发生在育空地区的第二个地点。在这项研究中增加的六个新德拉巴物种使加拿大和阿拉斯加的德拉巴总数达到65个。提供了所有这些物种的钥匙。

Abstract. Eleven new combinations are proposed in the recently established genus Blepharoglossum. Further, six names are found to be synonyms of earlier taxa in other genera and are here reduced to synonymy. Five names are also lectotypified, namely Dendrobium hastilabium, Eria dura, E. gracilicaulis, Habenaria zollingeri, and Trichotosia microbambusa.
摘要在最近建立的Blepharoglossum属中提出了11个新的组合。此外,还发现有6个名称与其他属的早期分类群同义,并在此归为同义。也有5个名称,即石斛(Dendrobium hastilabium)、硬毛毡(Eria dura)、细毛毡(E. gracilicaulis)、绿毛毡(Habenaria zollingeri)和微竹毛霉(Trichotosia microbambusa)。
