Se realiza una revisión taxonómica de Dendrophthora brachyclada, D. cupressoides, D. marmeladensis, D. moniliformis, D. picotensis y D. podocarpicola en Cuba, mediante observación y mediciones de caracteres morfológicos vegetativos y sexuales, además de datos sobre distribución geográfica, altitudinal, ecológica y de los hospederos que hemiparasita...
Dado que el número de estudios sobre el fitoplancton de la Serranía de Cuenca ha sido muy reducido hasta la fecha, esta nota describe las condiciones físico-químicas, la flora fitoplanctónica y su biovolumen estival en siete de sus ambientes estancados, enclavados en un territorio calizo donde la despoblación y el subsiguiente abandono de la agricu...
The name Senecio dombeyanus DC. has disparately been treated over time depending on the authors because of the uncertainty concerning the provenance of the original material, which was collected during the “Expedición Botánica al Virreinato del Perú”, namely by Joseph Dombey. This issue is clarified here, as well as its implications on the Bolivian...
We publish in this article a new species of tree of Drypetes (Putranjivaceae) from the Democratic Republic of the Congo and Republic of the Congo, D. palustris, which occurs in the Western Congolian Swamp Forests ecoregion. It is known from eight gatherings and we compare it with the species with the most similar morphology, D. calvescens, of which...
Macaronesian laurel forests harbour many herbs and laurophyllous trees with Mediterranean/European or Macaronesian affinities. Traditionally, the origin of these taxa has been explained by the relict hypothesis interpreting these taxa as relics of formerly widespread laurel forests in the European continent and the Mediterranean. We analysed the ph...
Oliveria is a little-known, monotypic genus of the family Apiaceae. The only accepted species, O. decumbens, is distributed throughout Mesopotamia. It is an annual, aromatic plant that has been used in traditional medicine since ancient times. The aim of this study was to examine morphological, micromorphological, and anatomical characters of O. de...
While studying the genus Amanita in Brazil, a specimen identified by J. Rick as Amanita spissa var. laeta was found. Its morphological analysis suggested that this material certainly corresponded to the one used in the protologue of this name. For this reason, it is designated here as the neotype.
Ecosystem services from wetlands include products such as food, water, fibers, timber, medicinal plants, and genetic resources for agriculture. One of the most abundant supplies is the raw material for basketry. In this study we aim to document the role of wetland plants as resources for basketry and broom-making in the Guadiana river basin and to ...
El incremento de las temperaturas regionales y la intensidad de uso de las tierras en el Escudo de Guayana y la Amazonia están imponiendo una reducción acelerada de las poblaciones de especies más sensibles, por lo que es urgente realizar inventarios biológicos en las zonas más vulnerables. Con la finalidad de conocer la diversidad y distribución d...
Molecular systematics requires the establishment of a robust phylogenetic framework including extensive geographical and taxonomic sampling. In this work, we proposed systematic changes in the genus Helianthemum based on phylogenetic trees obtained by both maximum likelihood and Bayesian analyses of GBS data. The implications of these phylogenetic ...
