Figure 3 . Time constants for leaf cooling (τ ) for bald
vs. hairy patches on the same leaf (MAGR, OLEU and PLOC) or on different
leaves (POTO, SOLY); in each case, the bald and hairy patches were at
equal distances from the leading edge of the leaf and were measured
simultaneously. Colors indicate species; small symbols represent results
from individual cooling curves, and large semi-transparent symbols
represent grand means within each species.
