Merostachys retrorsa is known from localities with an annual mean temperature of 25.3°C and precipitation of 2417 mm. Temperatures show relatively little seasonality (standard deviation ~45), varying from 31.6°C in the warmest month to 19.5°C in the coolest (isothermality ratio ~84.6). Precipitation shows considerable seasonality (coefficient of variation ~63.2), varying from 424 mm in the wettest month to 16 mm in the driest. The mean temperatures of the wettest (totaling 1182 mm) and driest (totaling 61 mm) quarters being 25°C and 25.3°C, respectively, and the mean precipitation of the warmest (28°C) and coolest (22.3°C) quarters being 413 mm and 840 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.
