Original: Spruces are large trees, from 20 â tall when mature, and can be distinguished by their whorled branches and conical form. The needles, or leaves, of spruce trees are attached singly to the branches in a spiral fashion, each needle on a small peg-like structure called a pulvinus.
Simplified: Spruces are large trees, from 20 â "60 (â" 95) m tall when mature, and can be distinguished by their conical form and their needles, that are attached singly to the branches in a spiral fashion.
