摘　　要：本文比较了野莴苣(Lactuca pulchella(Pursh)DC.)及其近似种毒莴苣(L.serriola L.)、乳苣(Mulgedium tataricum(L.)C.A.Mey.)的植株形态特征和瘦果形态特征,结果表明野莴苣植株可通过植株叶片形态、小花颜色和数量以及总苞片层数来加以鉴别;野莴苣瘦果可通过喙形状、纵肋数、瘦果表面刺毛形状、长度以及刺间距、千粒重等方面进行鉴别,并提供野莴苣重要鉴别特征描述和图片,以期为我国口岸检疫人员提供技术参考。The plant and achene morphological characteristics on Lactuca pulchella and its 2 similar species were compared in this paper. The results showed that blue lettuce plant could be distinguished by leaf shapes,colour and quantity of florets,number of bracts. And the achenes could be distinguished by beak shape,number of ribs,shape,length and spacing of surface bristle,and 1000-seed-weight. The descriptions and pictures of blue lettuce were provided for technical reference.
