- Observation Leaf temperature exceeded ambient air temperature by 0.71 to 9.58 K.
- Observation Large Helianthemum plants had leaf temperature 306.14.

- Observation Small Helianthemum plants had leaf temperature 308. 62.
- Observation Smaller plants had leaf temperature 2.48 K greater than larger plants.
- Association Transpiration transfer coefficient decreased as canopy size increased.
- Observation Large Helianthemum plants had transpiration transfer coefficient 0.41.
- Observation Medium Helianthemum plants had transpiration transfer coefficient 0.48.
- Observation Small Helianthemum plants had transpiration transfer coefficient 0.76.
- Observation The smaller plants had an 85% higher transpiration transfer coefficient than larger plants.
- Association Diurnal transpiration rate varied inversely with transpiration transfer coefficient.
- Association Smaller crown breadth was associated with worse root-area water condition and harder water stress.
- Observation The largest-crown plant had the highest transpiration rate, 9.42 × 10-6MJ m-2d-1.
- Method / resource Contactless thermal imaging was feasible for determining transpiration rates.
