Pinnate leaves are those in which the leaflets are arranged on the sides of a main leafstalk ; as in f\\ ay, Figs. 124-120. They ^^5^^ <F^y^ answer to \\\e feat lie r- \S\l/^J ^-^nt-'^ _ veined ( pinnatelif- reined) simple leaf; as will be seen at once on comparing the forms. The lenj- lets of the former answer to the lohes or divisions of the latter; and tlie con- tinuation of the peti- ole, along which the leaflets are arranged, that is, the leaf rachis answers to tlie inidrili of the simple leaf. 181. Three sorts of pinnate leaves are here giveii. Fig. 12-1 is piti- iKite with an odd or end leaflet, as in the Common and the Ash. Fig. is pinnate n:ith a tenJril at tlie end, in place of the odd leaflet, as in the Vetches and the Pea. Fig. 120 is eveidy or (dirupthj pinnate, as in the Honey Locust. 182. Palmate (also named digitate) leaves are those in which the leaflets are aU. borne on the tip of the leafstalk, as in the Lupine, the common Clover, the Virginia Creeper, the Horse-chestnut and Buckeye (Fig. 127). They evidently answer to the radiate veiried or pahnatebj veined simple leaf. 183. Either sort of compound leaf may have any number of leaflets; yet palmate leaves cannot well have a great many, since they are all crowded together on tlie end of the main leafstalk. Some Lupines have nine or eleven; tlie Horse-chestnut has seven, the Sweet Buckeye mure co
