Figure 5 . Boundary layer conductance to heat
(g bh), inferred from time constants for leaf
cooling, 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.
