Data from: Long-term ecological legacies in western Amazonia

Christine Åkesson, Crystal McMichael, Marco Raczka, Seringe Huisman, Johnny Vogel, Mona Palmeira, David Neill, Jason Veizaj & Mark Bush
1. Modifications of Amazonian forests by pre-Columbian peoples are thought to have left ecological legacies that have persisted to the modern day. Most Amazonian palaeoecological records do not, however, provide the required temporal resolution to document the nuanced changes of pre-Columbian disturbance or post-disturbance succession and recovery, making it difficult to detect any direct, or indirect, ecological legacies on tree species. 2. Here, we investigate the fossil pollen, phytolith, and charcoal history of Lake Kumpaka,...

Data from: Magnolia nuevoleonensis sp. nov. (Magnoliaceae) from northeastern Mexico and a key to species of section Macrophylla

José Antonio Vázquez-García, Reyna Domínguez-Yescas, Carlos Velazco-Macías, Viacheslav Shalisko & Rigoberto Efren Merino-Santi
We describe and illustrate Magnolia nuevoleonensis A. Vázquez & Domínguez-Yescas, a new deciduous tree species that belongs to M. sect. Macrophylla Figlar & Nooteboom. It is morphologically similar to M. ashei Weath., but differs from the latter in being a larger tree, with smaller flowers, larger and broadly ovoid (vs cylindrical to ellipsoid) fruits, prominently beaked (vs shortly beaked) carpels, and firm and short (vs flexible and elongated) styles.

Data from: Magnolia mercedesiarum (subsect. Talauma, Magnoliaceae): a new Andean species from northern Ecuador, with insights into its potential distribution

J. Antonio Vazquez-Garcia, David A. Neill, Viacheslav Shalisko, Frank Arroyo & R. Efren Merino-Santi
Magnolia mercedesiarum, a new species from the eastern slopes of the Andes in northern Ecuador, is described and illustrated, and a key to Ecuadorian Magnolia (subsect. Talauma) is provided. This species differs from M. vargasiana in having broadly elliptic leaves obtuse at the base vs. suborbicular and subcordate to cordate at the base, glabrous stipular scar, more numerous lateral veins per side and fewer stamens. It also differs from M. llanganatensis in having leaf blades...
