RESUMEN
We report the rediscovery of Rubuspendulus Rusby, "Mora India", described in 1933 from Colombia and not mentioned again until the present study. We also update its distribution with eight new localities in Colombia, seven in Ecuador and one in Peru, being a new record for the flora of the latter two countries. This is the first time that R.pendulus' stipules and flowers are found and detailed through a botanical description, illustrations and photographs. Rubuspendulus is morphologically differentiated from R.bogotensis Benth., R.mollifrons Focke, R.porphyromallos Focke and R.urticifolius Poir., with whom it was previously confused and we give a brief explanation on the type specimen status of R.mollifrons and R.porphyromallos.
RESUMEN
Two new species of Rubus (Rosaceae) from the western Andes of northern Ecuador are described. Rubuslongistipularis D.A. Espinel-Ortiz & Romol. is a scandent or climbing shrub found in the mountain forests of Chocó Andino from northern Ecuador. Rubusmaquipucunensis D.A. Espinel-Ortiz & Romol. is a vine or climbing shrub found in the rainforests of Chocó Andino from Pichincha and Santo Domingo de los Tsáchilas. The species mentioned here are morphologically differentiated from all the Rubus species from Ecuador with a detailed botanical description, illustrations and photographs. We also report, for the first time, possible hybridisation between R.longistipularis and R.boliviensis Focke, as the samples reviewed showed mixed characteristics from both species.
RESUMEN
We compiled a data set for all tree species collected to date in lowland Amazonian Ecuador in order to determine the number of tree species in the region. This data set has been extensively verified by taxonomists and is the most comprehensive attempt to evaluate the tree diversity in one of the richest species regions of the Amazon. We used four main sources of data: mounted specimens deposited in Ecuadorian herbaria only, specimen records of a large-scale 1-hectare-plot network (60 plots in total), data from the Missouri Botanical Garden Tropicos® database (MO), and literature sources. The list of 2,296 tree species names we provide in this data set is based on 47,486 herbarium records deposited in the following herbaria: Alfredo Paredes Herbarium (QAP), Catholic University Herbarium (QCA), Herbario Nacional del Ecuador (QCNE), Missouri Botanical Garden (MO), and records from an extensive sampling of 29,768 individuals with diameter at breast height (dbh) ≥10 cm recorded in our plot network. We also provide data for the relative abundance of species, geographic coordinates of specimens deposited in major herbaria around the world, whether the species is native or endemic, current hypothesis of geographic distribution, representative collections, and IUCN threat category for every species recorded to date in Amazonian Ecuador.
