我们在这里接受了单子叶植物是单系的假设，这是基于两个特征条件：（1）单子叶植物有一个子叶，或者根据另一种解释根本没有子叶，而双子叶植物有两个子叶。（其他数字，如0、1、3或更多，显然是次级衍生的）;（2）它们的筛管质体总是以三角体的形式积累蛋白质（图1），这是马兜铃科双子叶植物中仅有的两个属（Saruma和Asarum）所知的情况。
We have accepted here the hypothesis that the monocotyledons are monophyletic on the basis of two character conditions: (1) they have a single cotyledon, or according to an alternative interpretation no cotyledon at all, whereas the dicotyledons have two (other numbers such as 0, 1, 3 or more are obviously secondarily derived); (2) their sieve tube plastids, where investigated, always accumulate protein in the form of triangular bodies (Fig. 1), a condition known in the dicotyledons in only two genera (Saruma and Asarum) in Aristolochiaceae.
