Merostachys tatianae is known from localities with an annual mean temperature of 22.1°C and precipitation of 1229 mm. Temperatures show considerable seasonality (standard deviation ~205), varying from 30.5°C in the warmest month to 12°C in the coolest (isothermality ratio ~64.9). Precipitation shows considerable seasonality (coefficient of variation ~75), varying from 247 mm in the wettest month to 12 mm in the driest. The mean temperatures of the wettest (totaling 668 mm) and driest (totaling 40 mm) quarters being 23.7°C and 19.3°C, respectively, and the mean precipitation of the warmest (26°C) and coolest (15.8°C) quarters being 462 mm and 61 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.
