叶柄叶柄（Petiole）叶柄是叶片与茎的联系部分，其上端与叶片相连，下端着生在茎上。通常叶柄位于叶片的基部。少数植物的叶柄着生于叶片中央或略偏下方，称为盾状着生，如莲、千金藤。叶柄通常呈细圆柱形、扁平形或具沟漕。不同的植物，其叶柄的形状、粗细、长短都有所不同。有的叶柄长达一米以上，如棕榈；有的叶柄很短，近乎无柄，如金丝桃；有的叶柄极粗壮，如白菜；有的叶柄细长如牵牛；有的叶柄局部膨大成气囊，如水葫芦；有的叶柄基部形成膨大的关节，称为叶枕（pulvinus），可以调节叶片的位置和休眠运动，如含羞草；有的叶柄基部或全部扩大成鞘状，称为叶鞘，如伞形科植物叶的叶鞘；有些植物的真叶退化，叶柄特化成叶状称为叶状柄（phyllode），如金合欢属植物；有些植物的叶没有叶柄，叶片直接着生在茎上，称为无柄叶（sessileleaf）。有些无柄叶植物的叶片基部包围在茎上，称为抱茎叶（amplexicaulleaf），如苦荬菜。如果无柄叶的基部或对生无柄叶的基部彼此愈合，似被茎所贯穿，则称为穿茎叶或贯穿叶（perfoliateleaf），如元宝草。
