榆科榆科Ulmaceae双子叶植物纲金缕梅亚纲的一科。乔木或灌木。单叶互生，稀对生，常二列，羽状脉或基部3出脉，稀基部5出脉或掌状3出脉，有柄；托叶常呈膜质，侧生或柄内生，早落。单被花两性、单性或杂性，雌雄异株或同株，少数或多数排成聚伞花序，或因序轴短缩而呈簇生状，或单生，生叶腋或近新枝下部或近基部的苞腋；花被裂片4～8，雄蕊常与花被裂片同数而对生，雌蕊由2心皮连合而成，子房上位，通常1室，具1枚倒生胚珠。果为核果或小坚果，有时小坚果具翅。约16属230余种，主要产于北半球，分布于热带至寒温带。其中种较多的为朴属、山黄麻属、榆属和白颜树属；有4个单种属，即青檀、刺榆、水榆及Mirandaceltismonoica。中国有8属约50种，分布几遍全国，其中榆属占将近一半，青檀属为特有属。榆树榆科植物的化石仅发现落叶型，多数叶子边缘具齿，主要在北半球温带、暖温带和亚热带。最早在晚白垩世，在欧亚大陆和北美的第三纪地层中广泛地找到过榆树、朴树、榉树、刺榆、青檀、糙叶树及Ulminium等属植物的花粉化石、叶及内果皮。在中国发现榆科化石的地区为东北、华北、山东、陕西、新疆等省区。前人以形态性状为依据，将榆科分为两个族或两个亚科，近来得到了植物化学家的支持，但对某些属的归宿却有不同的意见，如J.哈钦森根据花、果、胚、子叶等性状，分榆科为榆族和朴族两族。榆科多数种类的木材坚硬、细致，耐磨损，韧性强，材质优良，可供家具、器具、建筑、车辆、桥梁、造船、农具等用；枝皮、树皮纤维强韧，可代麻制绳、织袋，或作造纸及人造棉原料。有些属（如白颜树属、朴属、糙叶树属、榆属等）的种子油可供工业用，榆属种子油还可供医药用及化工原料。某些生长较快、材质优良的乔木树种可作造林树种，尤其是榆属的某些种类(如白榆等)已在树种贫乏的温带地区广为种植。
