Elaphoglossum amygdalifolium holds a critical phylogenetic position as sister to the remaining ca. 600 extant species of Elaphoglossum and may provide important insight into the evolution of epiphytism in this clade of ferns. Here, we present the first examination of growth habit and gametophyte morphology for this species. We show that the cordate to(More)
Two new species of Protium (Burseraceae) are described and illustrated: Protium aguilariisp. nov., from the Pacific slope of the Osa Peninsula, Puntarenas Province, Costa Rica; and Protium hammeliisp. nov., from wet forests on the Caribbean slopes of Nicaragua and Costa Rica. In addition, Protium brenesiicomb. nov., is proposed as a new combination based on(More)
The tropical Andes of South America, the world's richest biodiversity hotspot, are home to many rapid radiations. While geological, climatic, and ecological processes collectively explain such radiations, their relative contributions are seldom examined within a single clade. We explore the contribution of these factors by applying a series of(More)
Two species of Siphocampylus (Campanulaceae: Lobelioideae) from the Central Andes of Peru and Bolivia are described, illustrated, and discussed with reference to related species. One species, Siphocampylus antonellii, is endemic to high elevation grasslands of Calca, Peru, while the second, Siphocampylus siberiensis, is endemic to cloud forests of(More)
We describe two new species of Pentaphylacaceae: Freziera monteverdensis from Costa Rica and Ternstroemia liesneriana from Panama. Line drawings, color images of living plants for one of the species, and discussions comparing the new species to their presumed closest relatives are provided. Describimos dos nuevas especies de Pentaphylacaceae: Freziera(More)
