Merostachys riedeliana is known from localities with an annual mean temperature of 20.2°C and precipitation of 1362 mm. Temperatures show considerable seasonality (standard deviation ~238.9), varying from 28°C in the warmest month to 10.6°C in the coolest (isothermality ratio ~60.7). Precipitation shows considerable seasonality (coefficient of variation ~61.7), varying from 318 mm in the wettest month to 14 mm in the driest. The mean temperatures of the wettest (totaling 948 mm) and driest (totaling 45 mm) quarters being 22.6°C and 17.1°C, respectively, and the mean precipitation of the warmest (26°C) and coolest (14.2°C) quarters being 564 mm and 123 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.
