The margin of the leaf is either e/iti?-e, or free from indenta- tions, as in the Lily-ol-Lhe-Valley ; Ji'aiged fiiih hairs, as in young Beech leaves ; it'my, as in the Oak ; crenate, or scalloped, as in the Violet; toothed; or lobed. If the teeth point outward it is termed dentate, the 'HoWy \ spifiously dentate : if upward, as in the Elm, the leaf is ser-iate or saw-edged. Whin a leaf is lobed or divided, its lobes or leaflets are arranged according to its venation, gener- ally palmately or pinnately. The division may extend to various depths from the margin towards the base or midrib, the leaf being termed sitnpk, it it does not extend all the way, and compound, if it divides the leaf into distinct leaflets. K palmate leaf of three leaflets is called ternate, as in Trefoils ; one of five, quinate, as in Cinqucfoil (p. 14S). In pinnate leaves it is important to notice whether there is a terminal (odd) leaflet or not ; how many pairs of leaflets there are : and if these are again divided up (bi-pinnate). If there is a terminal lobe or leaflet larger than the rest. as in the White Mustard, the leaf is called lyrate. In describing a compound leaf it is generally only necessary to mention the type on which the leaflets are arranged, whether palmate or pinnate, and to describe one leaflet as if it were a simple leaf. If a leaf be divided up into such fine segments that.
