Merostachys mexicana is known from localities with an annual mean temperature of 25.4°C and precipitation of 1830 mm. Temperatures show moderate seasonality (standard deviation ~177.4), varying from 35.1°C in the warmest month to 16.4°C in the coolest (isothermality ratio ~65). Precipitation shows considerable seasonality (coefficient of variation ~77.7), varying from 366 mm in the wettest month to 7 mm in the driest. The mean temperatures of the wettest (totaling 916 mm) and driest (totaling 24 mm) quarters being 26°C and 24.8°C, respectively, and the mean precipitation of the warmest (28.5°C) and coolest (22.6°C) quarters being 463 mm and 185 mm, respectively.

Tables and figures are dynamically generated by intersecting georeferenced herbarium specimen localities with 10 minute resolution WorldClim v2.1 variables (Fick and Hijmans 2017). The above data are subject to change as specimens and geocoordinates are added, removed or altered.
