Arthrostylidium simpliciusculum is known from localities with an annual mean temperature of 26.1°C and precipitation of 2655 mm. Temperatures show relatively little seasonality (standard deviation ~59.5), varying from 32.3°C in the warmest month to 20.1°C in the coolest (isothermality ratio ~79.2). Precipitation shows moderate seasonality (coefficient of variation ~36.3), varying from 359 mm in the wettest month to 12 mm in the driest. The mean temperatures of the wettest (totaling 1001 mm) and driest (totaling 57 mm) quarters being 25.8°C and 26.3°C, respectively, and the mean precipitation of the warmest (27.6°C) and coolest (24.7°C) quarters being 499 mm and 787 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.
