Pinnate with a tendril, when the footstalk is prolonged into a tendril, as in Fig. 129, and all of the Pea tribe. 148. Pinnate leaves may have many or few leaflets. The Bean has pinnate leaves of only 131. Pilmale leaf, of 6 leaSets. thrCB leaflets. 149. Palmate leaves generally have few leaflets; there is not room for many on the very end of the footstalk. Common Clover has a palmate leaf of three leaflets (Fig. 136) ; Yirginia Creeper, one of five -leaflets (Fig. 72), as well as the Buckeye (Fig. 131); while the Horsechestnut has seven, and some Lupines frpm eleven to seventeen. 150. Twice or Thrice Compound leaves are not uncommon, both of the pinnate and of the palmate sorts. While some leaves of Honey-Locust are only once pinnate, as in Fig. 130, others are doubly or twice pinnate, as in Fig. 132. Those of many Acacias are thrice pinnate. Fig. 133 represents one of the root-leaves of Meadow-Rue, which is of the palmate kind, and its general footstalk is divided into threes for four times in suc- cession, making in all eighty-one leaflets! When, a leaf is divided three or four times, it is said to be decompound. This is ter- na^e^^ decompound, because it divides each time into 132.
