Not illustrated. 1897 Excerpt: ...from the base of the blade separate widely, we say it is palmately veined. If the large veins are branches of a midrib the leaf is pinnately veined. Deeply lobed leaves are pinnately or palmately parted (Fig. 46, b and e). Divided leaves are cut quite to the midrib if pinnately, or to the base if palmately divided. Leaves are cleft when the sinuses between the lobes are sharp. It is common to give the number of lobes in the descriptive phrase. In Fig 46, c is palmately five-lobed, and e is palmately five-parted. Pinnately lobed, parted, and divided leaves come under the general term pinnatifid. When the lobes are pinnatifid the leaf is bi-pinnatifid. Fig. 47. a. Palmately S-foliolate leaf of clover with lacerate adnate stipules. b-Pinnately 3-foliolate leaf of bur-clover with free lanceolate stipules. Compound leaves have distinctly separated leaflets, which are joined to a common petiole in palmate leaves (Fig. 47, a), and to a prolongation of it called a rachis in pinnate leaves (Fig. 46, d). Clover leaves are usually palmately 3-foliolate. Bur-clover is pinnately 3-foliolate (Fig. 47). An abruptly pinnate leaf has no terminal leaflet. Leaves may be twice or thrice compound; that is, the leaflets may be compound. Such leaves are said to be decompound. In a tri-pinnate leaf the leaflets of the leaflets are pinnate. Keep all your leaves and find if you can other kinds for the next exercise. Leaves of locust, ailantus (tree of heaven), acacia, lupine, strawbeny, elderberry, etc. may be added to your collection.
