Olyra holttumiana is known from localities with an annual mean temperature of 26.1°C and precipitation of 2587 mm. Temperatures show relatively little seasonality (standard deviation ~64.3), varying from 30.2°C in the warmest month to 22.2°C in the coolest (isothermality ratio ~76.3). Precipitation shows considerable seasonality (coefficient of variation ~52), varying from 371 mm in the wettest month to 20 mm in the driest. The mean temperatures of the wettest (totaling 1027 mm) and driest (totaling 92 mm) quarters being 25.6°C and 26.5°C, respectively, and the mean precipitation of the warmest (27.4°C) and coolest (25.3°C) quarters being 391 mm and 820 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.
