FIGURE 1 in Adelobotrys tessmannii (Merianieae, Melastomataceae) and allies: a refined circumscription and description of two new Amazonian species with notes on their ecology
FIGURE 1. Localities (n=390) of quantitative species inventories (n=396) and soil sampling for estimating soil preferences of the species treated here. Individuals of the species were found in the localities as follows: orange dot = Adelobotrys latifolius, green dot = A. microcarpus, violet dot = A. tessmannii; in one locality two species were found. The four separate regions in which field studies were carried out and where at least one of the three species was encountered are marked (Madre de Dios in southern Peru, Loreto in northern Peru, Yasuní in Ecuador and Juruá in central Brazil). Elevation is depicted as follows: 0–1000 m as white; 1001–2000 m, 2001–3000 m, 3001–4000 m, and>4000 m as progressively darker shades of grey. For approximate location of map section in South America, see Fig. 3D.
