Two new endemic species of Bactris, found in the understorey of humid forest on the Pacific Coast of Costa Rica, are described and illustrated. Bactris ana-juliae is 1.8-3.0 m tall, and B. herrerana is 2.0-3.0 m tall.

Pollination of Neotropical dioecious trees is commonly related to generalist insects. Similar data for non‐tree species with separated genders are inconclusive. Recent studies on pollination of dioecious Chamaedorea palms ...

Information on genetic variation and its distribution in tropical plant populations relies mainly on studies of ground‐rooted species, while genetic information of epiphytic plants is still limited. Particularly, the effect ...

The northern Neotropical region is characterized by a heterogeneous geological and climatic history. Recent studies have shown contrasting patterns regarding the role of geographic elements as barriers that could have ...

We analyzed the differences in species richness, community composition, population structure and within-tree location of epiphytic bromeliads in contiguous secondary and mature forests in a premontane area in Costa Rica. ...

Plant community composition is the combined result of species‐specific competitive abilities and the availability of propagules. For epiphytic plants, current hypotheses consider that dispersal‐related factors are most ...

Predispersal characteristics that affect the reproductive success in plants may influence their colonizing ability. We evaluated this hypothesis in two sympatric epiphytic bromeliads in Costa Rica, Guzmania monostachia and ...

General descriptions and taxonomic keys to the nine genera (Bernoullia, Ceiba, Huberodendron, Matisia, Ochroma, Pachira, Pseudobombax, Quararibea, and Spirotheca) and twenty-four species of Bombacaceae species known to ...

La documentación florística de El Rodeo se remonta a finales del siglo XIX y a la fecha se conocen 1 034 especies de plantas vasculares nativas o naturalizadas y 47 especies introducidas cultivadas (ornamentals o de interés ...
