Merostachys petiolata is known from localities with an annual mean temperature of 20.7°C and precipitation of 1534 mm. Temperatures show considerable seasonality (standard deviation ~224.4), varying from 28.7°C in the warmest month to 11.5°C in the coolest (isothermality ratio ~60.4). Precipitation shows considerable seasonality (coefficient of variation ~57.8), varying from 333 mm in the wettest month to 18 mm in the driest. The mean temperatures of the wettest (totaling 960 mm) and driest (totaling 62 mm) quarters being 23.2°C and 17.9°C, respectively, and the mean precipitation of the warmest (25.7°C) and coolest (15.4°C) quarters being 613 mm and 146 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.
