Botany of the Southern states . Tripinnate leaf. Unequally pinnate leaf. 94. To what varieties may all compound Teaves be reduced 1 What is apinnate leaf? When bipinnate! LEAVES. 57 still further and form the tripinnate leaf, as in the Thalictrum(Fig. 87), and it even exceeds this subdivision when the termsupra-decompound is applied to them, no matter how far thedivisions may extend. When the midrib is terminated by aleaflet, the leaf is said to be unequally pinnate. (Fig. 88.) 95. The radiated form of reticulated leaves often assumes thecompound structure, as in the JEsculus, Lupinus, Clover, &c.(Fig. 63), and are then called digitate. If there are three leaf Fig. Ternate leaf. lets, it is called a ternate leaf. (Fig. 90.) If subdivided bythree, they are bi-ternate, tri-ternate, &c. (Fig. 91.) 96. Besides the preceding varieties of leaves, which may beconsidered their common forms, they often assume a variety ofmodifications which deserve a special attention. These varia-tions arise from a variety of causes, which will be noticed underthe several examples which we shall adduce. A cohesion of Fig. 91.
