蓝睡莲（Nymphaea coerulea）、蓝睡莲N.对荷花和水仙的单子叶和双子叶性状进行了研究。子叶的形成可以解释为一个单一的双叶结构或两个独立的子叶。然而，存在一个盖和识别胚芽鞘和中胚轴类似的禾本科和莎草的理由包括睡莲科单子叶植物。下胚轴和胚根的形态以及叶型支持了一个特化科的地位，即属于或接近于Helobiae。
Seedlings ofNymphaea coerulea, N. lotusandNuphar luteumwere examined for monocotyledonous and dicotyledonous characters. The cotyledonary formation could be interpreted either as a single bilobed structure or as two separate cotyledons. However, the presence of an operculum and the recognition of a coleoptile and mesocotyl similar to those of grasses and sedges gave grounds for including Nymphaeaceae in the monocotyledons. The form of the hypocotyl and radicle and the leaf-type supported a position, as a specialized family, in or close to the Helobiae.
