Plants of this class usually have two seed leaves, or cotyledons, and cambium tissue in the stems (see meristem). Much the larger of the two classes of flowering plants, dicots are divided into many families, among which several of the more conspicuous and easily recognized are the willow, buttercup, pink, mustard, saxifrage, rose, pea, heather (see heath), gentian, bluebell, and aster families.
