猬草属

对猬草属和赖草属以及近缘属披碱草属植物的叶表皮微形态和叶片横切面解剖结构进行了观察。

The leaf epidermal micromorphology and anatomical structure of Hystrix , Leymus and Elymus was examined under light microscope .

42个引物产生的290条谱带中，257条（88.62%）表现出多态性，说明披碱草属、鹅观草属和猬草属3个属的模式种间具有丰富的遗传多样性。

257 bands ( 88.62 % ) behave polymorphic in 290 RAPD bands amplified by 42 random primers , indicating extensive genetic diversity among the type species of Elymus , Roegneria and Hystrix .
