Merostachys claussenii is known from localities with an annual mean temperature of 20.2°C and precipitation of 1729 mm. Temperatures show considerable seasonality (standard deviation ~340.6), varying from 30.6°C in the warmest month to 9°C in the coolest (isothermality ratio ~57.1). Precipitation shows relatively little seasonality (coefficient of variation ~23.5), varying from 385 mm in the wettest month to 4 mm in the driest. The mean temperatures of the wettest (totaling 1076 mm) and driest (totaling 24 mm) quarters being 21.6°C and 17°C, respectively, and the mean precipitation of the warmest (26.1°C) and coolest (12.3°C) quarters being 467 mm and 334 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.
