FIGURE 2 in The rediscovery of Lobelia macrocentron (Campanulaceae) after 169 years, with notes on the morphology, habitat and conservation status

FIGURE 2. Distribution map of Lobelia macrocentron (red dots); the red line indicates Seemann's exploration track (1849–1850) within which the original locality of the species remains unclear. The portion between Mazatlán and Durango corresponds to the old (non-toll) road, which was the only one available at that time. The star represents the town El Palmito, and the polygon of Santuario El Palmito is highlighted in green. The squares corresponds to the localities mentioned by Seemann in his itinerary (1 Mazatlán, 2 San Sebastián (currently Concordia), 3 Copala, 4 Santa Lucía, 5 El Salto, 6 Llano Grande, 7 Navíos, 8 Mimbres, 9 Durango, 10 San Francisco del Mezquital, 11 La Guajolota, 12 Santa Teresa, and 13 Tepic).
