Mammillaria mathildae, a narrow endemic species known only from limited populations around the capital city of Querétaro, and Physalis longiloba and P. waterfallii are endemic species known only from Jalisco in western México and Michoacán, are recorded for the first time from Guanajuato. The three species were previously known only from the states of Jalisco, Michoacán, and Querétaro. [ABSTRACT FROM AUTHOR]
