Summary statement : We provide the first unambiguous experimental proof that leaf trichomes (colloquially known as leaf hairs) slow down the transport of heat between leaves and the air.
Short title : Leaf trichomes reduce boundary layer conductance
Author contributions : TNB and LS conceived the project. TNB and MAP refined the project scope, designed and built the apparatus, and conducted the experiments. TNB performed the analysis and modeling. MAP and TNB drafted the manuscript. All authors edited the manuscript.
