The study of Namurian Flora is not so well advanced because of the limited geographic distribution of the plants in the world, even the stage had been taken place by Serpukhovian and Bashkirian due to the middle borderline between Upper and Lower Carbeniferous passing through the ammonite subzone E2 and subzone H1 of Namurian A, thus there are not so many practical papers subjected to the plants of this stage like the other periods these years.
纳缪尔期植物群的研究工作因受到该期地层分布的局限性而不如其他地史时期植物群研究地深入，甚至由于纳缪尔阶A期菊石E_2与H_1亚带之间的界线亦是上下石炭统的分界线，所以在近年来的《国际地层表》中该阶名也逐渐被塞普霍夫阶和巴斯基尔阶所代替。
