"When the stem leaves grow directly across from each other, in pairs, the leaves are called opposite; when they grow in circles of threes, fours, fives, and so on, they are termed whorled. If... the leaves are arranged singly on the stem, first at one point and then at another, they are alternate." — Lawrence Newcomb, Newcomb's Wildflower Guide
