FIGURE 4 in Magnolia mercedesiarum (subsect. Talauma, Magnoliaceae): a new Andean species from northern Ecuador, with insights into its potential distribution
FIGURE 4. Localities of M. mercedesiarum and minimal convex polygon. Basemap from GMTED2010 digital elevation model (Danielson and Gesch 2011) and ESRI World administrative divisions (ESRI 2017). Colour gradient represents elevation. Extent of occurrence as defined by the IUCN (2012) is 901 km².

FIGURE 5 in Magnolia mercedesiarum (subsect. Talauma, Magnoliaceae): a new Andean species from northern Ecuador, with insights into its potential distribution
FIGURE 5. Potential distribution area of Magnolia mercedesiarum after threshold application. Both conservative (equal training sensitivity and specificity, ETSS) and less conservative (maximum sum of training specificity and sensitivity, MTSS) thresholds included. Colour indication for MTSS is the additional area included in potential distribution around the edges of the coverage with the MTSS threshold. Base map is the same as in Figure 4.
Data from: Magnolia mercedesiarum (subsect. Talauma, Magnoliaceae): a new Andean species from northern Ecuador, with insights into its potential distribution
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 broadly elliptic vs. elliptic, longer petioles, less numerous lateral leaf veins per side; larger fruits, and more numerous petals and carpels. Using MaxEnt species distribution models and IUCN threat criteria, M. mercedesiarum has a potential distribution area of less than 3307 km² and is assessed as Endangered (EN): B1 ab (i, ii, iii). The relevance of systematic vegetation sampling in the discovery of rare species is highlighted.
