Bark (botany)
Bark was the external layer of a tree.

In 2267, Spock appreciated the tensile cohesion of bark used to make a bowstring. ()

Trevis, Neelix, and Naomi Wildman all made "silly puns" about the tree character; twice about his  being worse than his bite, and once about getting hot under the bark (aka collar). ()
