Plant species
Buddleja cordata is a dioecious tree that is widely distributed across the valley of Mexico in elevations between 2,250 to 3,000 m (Vargas 2001). Its leaves are pubescent, elliptical, and 5.5 to 24 cm long. Flowers are small, organized in large panicles and present from June to February. This plant produces small fruits (2.5 to 6 mm) from October to April (Norman 2000, Vargas 2001). Its height varies between 1 to 20 m, but in the REPSA, most individuals are shorter than 7 m. During this study, B. cordata flowered from June 2010 to September 2010, and fructified from September 2010 to January 2011.
