No matter how much the lamina may be divided, if the divi-sions are not articulated to a common petiole, the leaf is simple;and if the lamina is not divided at all, but articulated to thepetiole, the leaf is compound, as in the Orange. The principleof formation of this class of leaves will be readily understood bythe above explanation of simple leaves. 94. All compound leaves may be reduced to two varieties,corresponding to the feather- veined and radiated forms of retic-ulated leaves. If we recur to the feather-veined leaf given above,and conceive each of
