“…Although Costa Rica is considered one of the best explored tropical countries botanically, new occurrence records are to be expected for members of the aquatic flora that are known both to the north and south of the country, but that have eluded previous detection. As it has been shown (Crow et al, 1987;Blanco and Jiménez, 2019;Acuña-Castillo et al, 2021, and the present contribution), some new records were from poorly collected wetland localities that may be considered "less spectacular" than Palo Verde in Guanacaste, Caño Negro in Alajuela and Tortuguero in Limón, underlining the importance of also inventorying small wetlands.…”

Antecedentes y Objetivos: Ricciocarpos natans es una de las pocas especies de hepáticas verdaderamente acuáticas. Tiene una distribución subcosmopolita y parece ser más común en áreas templadas. La especie ha sido considerada muy rara en América Central, donde solo se conocía de Panamá. El objetivo de este estudio es reportar la presencia de esta especie en Costa Rica y revisar su distribución en América Latina.Métodos: Brindamos una descripción general de la distribución de la hepática acuática flotante Ricciocarpos natans en América Latina con base en la literatura, especímenes de herbario y registros fotográficos inequívocos en toda la región, así como trabajo de campo en Costa Rica.Resultados clave: Ricciocarpos natans se reporta como nueva para Costa Rica. Brindamos el estudio más completo hasta la fecha de la distribución geográfica de la especie en América Latina.Conclusiones: Nuestro estudio muestra que Ricciocarpos natans parece ser más común y más ampliamente distribuida en el Neotrópico de lo que se suponía anteriormente. Su supuesta rareza parece ser el resultado de esfuerzos de recolección insuficientes.

“…The Lemnoideae is a pantropical group of five genera and 47 species are minute floating aquatics (Boyce & Croat, 2011). The members of this subfamily can occur in permanent or seasonal lentic habitats, lotic habitats, and, rarely, can grow on mud, wet rock walls, or in the drip of waterfalls (Landolt, 1986(Landolt, , 1998(Landolt, , 2000; in some cases, large colonies comprising up to three Lemnoideae species can grow on waterfall's vertical rocks at the same time (Blanco & Jiménez, 2019). The most outstanding characteristic of this group is its small size, the reduction of its organs and the small morphological differentiation.…”

This paper discusses the family Araceae, emphasizing its worldwide distribution and the diversity of morphological and ecological characteristics of the family that have enabled it to reach such a prominent position with diverse habitats. Few families of its size have come to inhabit such a diverse spectrum of habits and biomes. The family has important habit forms and growth structures that have enabled such distributional patterns. The very broad spectrum of life forms it demonstrates is one of the main characteristics of the family, namely broad habitat diversity. This coupled with high species diversity; high rates of endemism and the presence of large numbers of unknown species (probably the highest of any family percentage-wise) constitute principal characteristics of the family.

Background and Aims: Araceae is a worldwide family of herbaceous plants, most notable for its striking morphological diversity and broad habitat diversity. It comprises eight subfamilies, 143 genera, and 3667 species. The Central American region has about 780 species, of which 262 are distributed in Costa Rica. In this contribution, we include four new aroid records for the Costa Rican flora belonging to the genera Anthurium, Philodendron, and Spathiphyllum. In addition, nomenclatural aspects of A. myosuroides are discussed. Methods: The new records resulted from fieldwork on Fila Anguciana, Cerro Turrubares, and Volcán Miravalles. The correct taxonomic identity of the species was confirmed based on literature and comparison with herbarium specimens, especially type specimens from the herbaria of the Universidad de Panama (PMA) and the Missouri Botanical Garden (MO), as well as consultation of the JSTOR Global Plants database and the collections of the Muséum National d'Histoire Naturelle de Paris (P) online. Descriptions, taxonomic discussions, and figures of the morphological characteristics of the new records are provided. Key results: We present Anthurium roseospadix, A. myosuroides, Philodendron pseudauriculatum and Spathiphyllum dressleri as new records for the Costa Rican flora. Moreover, lectotypification for Pothos myosuroides is proposed. Conclusions: Considering the new records presented in this work, the aroid flora of Costa Rica now comprises 266 species, and the total species numbers for Anthurium, Philodendron, and Spathiphyllum increased to 94, 63, and 10, respectively.
