Abstract. Bacopa llanorum, a new species from the seasonally flooded savannas of the “Llanos” region of Colombia (Arauca department) is described and illustrated, and its morphological relationships are discussed. On the basis of its dimorphic leaves (the innermost blade filiform, uppermost lanceolate-ovate), the new species does not appear to be allied to any other Bacopa species. However, it shares several other features with B. reptans. A new combination, Bacopa debilis, is proposed to replace Caconapea debilis. In addition, ecological information of the genus in “Los Llanos” of Colombia and Venezuela, and ecological and floristic notes about the eolic-limose plains, are included. A key for identifying species of Bacopa in this region is also provided. Bacopa llanorum is remarkable for its foliar dimorphism, in an otherwise predominantly homomorphic-leaved genus, and it increases to 20 the number of species of the genus in the “Llanos del Orinoco” bioregion.
摘要对哥伦比亚“大草原”地区(阿劳卡省)季节性洪水稀树草原上的一新种马尾草(Bacopa llanorum)进行了描述和说明，并对其形态关系进行了讨论。根据它的二形叶(最里面的叶片丝状，最上面的叶片披针形-卵形)，这个新种似乎与任何其他假马齿苋物种都没有亲缘关系。然而，它与B. reptans有几个共同的特征。提出了一种新的组合假马齿苋代替假马齿苋。此外，还包括哥伦比亚和委内瑞拉“Los Llanos”属的生态信息，以及关于eolic-limose平原的生态和区系记录。为该地区假马齿苋的种类鉴定提供了一个关键。在一个以同态叶为主的属中，假马齿苋(Bacopa llanorum)以其叶片二形性而闻名，使“Llanos del Orinoco”生物区该属的物种数量增加到20种。

Abstract. Lepanthes is one of the most species-rich genera of orchids in the Neotropics, with most of the species found in medium to high elevation forests and few species in lowlands. We describe and illustrate Lepanthes osaensis, a new species from the very wet lowland forest of Península de Osa, Costa Rica. It is similar to Lepanthes cuspidata but differs mostly in the vinous leaves; smaller sepals; the narrower, bilobed petals; and the smaller lip with triangular blades. Notes on its distribution, habitat, flowering, and conservation status, as well as discussion of a taxon with similar morphology, are provided.
摘要Lepanthes是新热带地区种类最丰富的兰花属之一，大多数种类分布在中高海拔的森林中，少数种类分布在低地。我们描述和说明Lepanthes osaensis，一个新的物种从非常潮湿的低地森林Península de Osa，哥斯达黎加。它类似于虎皮草，但主要不同于毒叶;萼片小;较窄的双叶花瓣;小一点的唇上有三角形的叶片。对其分布、生境、开花和保护状况作了说明，并讨论了一个形态相似的分类群。

Abstract. Five new combinations in Myriopus (Heliotropiaceae) are proposed in this paper: Myriopus andrade-limae, M. isabellinus, M. mapirensis, M. selleanus, and M. subsessilis. Myriopus isabellinus and M. selleanus are restricted to Costa Rica and Haiti, respectively, and other three species are distributed in South America; M. andrade-limae is endemic to Brazil.

Abstract. Species of Oudemansiella are distributed worldwide mainly in tropical to south temperate zones. Morphological identification of the species is usually complex and may even be ambiguous, especially for O. canarii and O. cubensis, since they share many similar characters. They have been considered synonyms by several authors. There are no recent descriptions or detailed illustrations of Oudemansiella species from Argentina, and molecular data are practically null. In this work these species were described and illustrated making use of new collections, culture data, and nrITS phylogenetic analysis. It was not possible on the basis of the results to differentiate the species macroscopically, but these were differentiated at the microscopic level, mainly by their pileipellis structure. Phylogenetic analysis from nrITS sequences enabled the molecular identification of these two species, and the cultivation of basidiomes on lignocellulosic substrate allowed us to affirm that both species have a hemiangiocarpic development.

Abstract. We provide a general introduction to the prodromi to Flora Costaricensis, and an introduction to the precursors of subtribe Pleurothallidinae. We present a systematic revision of the genus Echinosepala for the flora of Costa Rica and a detailed discussion of molecular evidence with regard to most Costa Rican taxa, aimed at phylogenetically framing Echinosepala within the subtribe Pleurothallidinae, recognizing internal relationships among the species in the genus, and proposing evolutionary hypotheses. We recognize 10 species of Echinosepala in Costa Rica. Each species is described and illustrated with one or more botanical drawings and photographs, all based on Costa Rican material. Etymology, distribution, ecology, distinguishing features, and affinities with other taxa in the genus are discussed, taxonomic notes are provided, and a list of selected material examined for this study is included for each taxon. Two new species of Echinosepala, E. glenioides and E. isthmica, are described and illustrated, and their relationships are discussed. New combinations are proposed in Echinosepala for Pleurothallis alexandrae and P. pastacensis, and the former species is neotypified.

Abstract. Two new species of Podandrogyne, P. flammea, endemic to Pacific coastal and western Andean Ecuador and Colombia, and P. websteri, restricted to four northern provinces of Ecuador but found mostly in Pichincha, are described and illustrated. These taxa are generally distinguished by flower and fruit size and leaf blade number and texture. A general likeness suggests affinity to the species cluster represented by P. glabra.
