The leaflets of compound leaves are described in the same terms as are used in describing simple leaves. Ternate leaves are either pinnately ternate or palmately ternate, according as the leaflets are petiolate or sessile or subsessile. The petiole is usually cylindric or semi - cylindric in form, with often a more or less grooved upper surface. In Orange and other plants of this family the petiole is winged and articulated to the blade. In some plants the two mar- gins of the blade run down the two sides of the petiole as two narrow strips. The leaf in such cases is said to be decur- RENT. The petiole is usually attached to the base of the blade; in some leaves, however, as in padma or Lotus, nil-padma (^Nymphcea stellatd), kachu {Colocasia), Garden Nasturtium (Tropceolum majus), &c., the petiole is attached to the back of the leaf; such a leaf is said to be peltate (fig. 43). Often the petiole is accompanied by appendages known as stipules. They are usually green, folia- ceous, filiform, or scaly structures seen by the side of.
