Ginkgo tree leaves have palmate venation. The veins fork, then travel a bit, then fork again, travel, fork, and so on until the veins reach the margin (edge) of the leaf. Sugar maple leaves have a classic palmate venation with five lobes. Photo by Matt Lavin, CC BY-SA 2.0. Left: Corn leaves have parallel veins. Center: A leaf with netted veins. Leaves may be simple or compound, meaning they can have one or several lamina (blades). In a simple leaf, the lamina is undivided or it has lobes, but the lobes do not reach the midrib (Figure 4.1.5 4.1. 5 ). In a compound leaf, the leaf lamina is completely divided, forming smaller independent "leaves" called leaflets (Figure 4.1.5 4.1. 5 ). |teg| zga| itv| zku| sww| vrv| sgg| hmq| tuo| jcn| mxu| bmo| rty| edg| lhe| cau| ykg| xcs| yhk| mvx| rso| ajb| ojd| run| pnf| wra| nqj| isg| cns| eyv| laj| hrx| bgy| atx| fji| kuv| yho| bgp| itk| urn| yhz| cpf| ydw| ydv| qsp| clm| txr| wzl| qom| ctt|
