Arthrostylidium merostachyoides is known from localities with an annual mean temperature of 21.2°C and precipitation of 2616 mm. Temperatures show relatively little seasonality (standard deviation ~67.1), varying from 27.4°C in the warmest month to 15.7°C in the coolest (isothermality ratio ~77.6). Precipitation shows considerable seasonality (coefficient of variation ~60.2), varying from 438 mm in the wettest month to 1 mm in the driest. The mean temperatures of the wettest (totaling 1194 mm) and driest (totaling 8 mm) quarters being 21.1°C and 21.4°C, respectively, and the mean precipitation of the warmest (27.9°C) and coolest (15.1°C) quarters being 452 mm and 539 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.
