Table 2 . Species and genotypes examined in this study. Four-letter species codes are given in parentheses. reps : numbers of leaves, wind speeds, and cooling curves measured; bald/hairy comparison : whether measurements were compared between bald and hairy patches on the same leaf, or between bald and hairy leaves; leaf heat capacity : calculated from measured leaf area, water content and dry mass, assuming heat capacities of 4.184 and 1.5 J g-1 K-1 for water and dry mass, respectively. Trichome length (trichome layer depth) of the five experimental species. SOLY trichome depth was measured in 3-5 leaves for each species, except for SOLY, which was measured in images provided by Gasparini et al. (2021) for the same mutant (means ± SE).
