Arthrostylidium grandifolium is known from localities with an annual mean temperature of 26.4°C and precipitation of 2756 mm. Temperatures show relatively little seasonality (standard deviation ~61.6), varying from 33.6°C in the warmest month to 19.9°C in the coolest (isothermality ratio ~74.9). Precipitation shows considerable seasonality (coefficient of variation ~51.7), varying from 462 mm in the wettest month to 19 mm in the driest. The mean temperatures of the wettest (totaling 1350 mm) and driest (totaling 89 mm) quarters being 25.8°C and 26.9°C, respectively, and the mean precipitation of the warmest (28.1°C) and coolest (25.2°C) quarters being 334 mm and 1076 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.
