thorn
(thôrn)1. A short, hard, pointed part of a stem or branch of a woody plant.
2. Any of various plants bearing thorns.
Usage It hardly makes a difference whether you get pricked by a thorn or a spine—it hurts just the same. But a person who studies plants might think there was a difference. Scientifically speaking, a thorn is a hard, pointed part of a stem or branch of a woody plant. While the word spine is used loosely to refer to any hard, pointed structure on a plant, it more properly refers to a leaf that has evolved into a narrow, sharp projection to conserve water and protect the stem, which stores water. Thus a cactus has spines but not thorns, and a rose bush and hawthorn have thorns but not spines.
