Trees · question 2

What do the needles look like?

Small scales pressed against the twig: Usually flat sprays that look like fern fronds (round and cord-like in the giant redwood); you see no separate needles.
Needles in bundles of 2 or 5: At the base, a papery little sheath holds the needles together.
Needles in dense tufts of 10 or more: They sit like little brushes on short, stubby side shoots.
Single needles, one by one: Each needle grows separately on the twig (sometimes in whorls of three).
Broad, triangular, sharp-pointed leaves: Overlapping like roof tiles all around thick, snake-like branches.
