In the episode of CSI NY on right now, they identified trace evidence as coming from Eastern White Pine. “Lindsay” runs outside to a tree, which she identifies as Eastern White Pine. A tree with short needles (a couple mm long). Eastern White Pine has long, flexible needles, 5-13 cm long. Sure, it was a gymnosperm, but a white pine? Maybe a juniper, not a pine of any sort.
As usual, botany gets short shrift.
