Merostachys annulifera is known from localities with an annual mean temperature of 22.6°C and precipitation of 1032 mm. Temperatures show moderate seasonality (standard deviation ~154.1), varying from 28.6°C in the warmest month to 16.3°C in the coolest (isothermality ratio ~64.5). Precipitation shows moderate seasonality (coefficient of variation ~30.8), varying from 166 mm in the wettest month to 4 mm in the driest. The mean temperatures of the wettest (totaling 460 mm) and driest (totaling 20 mm) quarters being 23.8°C and 21.2°C, respectively, and the mean precipitation of the warmest (25.7°C) and coolest (17.8°C) quarters being 303 mm and 215 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.
