Arthrostylidium distichum is known from localities with an annual mean temperature of 24.3°C and precipitation of 1578 mm. Temperatures show considerable seasonality (standard deviation ~213.1), varying from 31.4°C in the warmest month to 16.1°C in the coolest (isothermality ratio ~62.3). Precipitation shows considerable seasonality (coefficient of variation ~55.3), varying from 226 mm in the wettest month to 53 mm in the driest. The mean temperatures of the wettest (totaling 652 mm) and driest (totaling 181 mm) quarters being 26.5°C and 21.4°C, respectively, and the mean precipitation of the warmest (26.6°C) and coolest (21.4°C) quarters being 636 mm and 181 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.
