摘要
A hyaline, unvascularized sheath envelops a portion of the inflorescence near maturity. Though resembling an appendage of the main axis, in early ontogeny it develops as a prophyll of the renewal growth apex below the inflorescence. Two flowers develop on the inflorescence axis, subopposite each other. Fertile appendages are initiated in an acropetal sequence on each floral bud. The first to form, in the median position, are the two stamens, the lower preceding the upper. Each stamen develops two bisporangiate thecae separated by a broad connective. A dorsiventral outgrowth is initiated slightly abaxially near the tip of the connective at the stage of theca differentiation. This outgrowth appears to be homologous with a similar outgrowth in Potamogeton densus, but not with the sterile appendages of the Potamogeton flower which, by some authors, have incorrectly been interpreted as connective outgrowths. Each carpel arises as a radial primordium which becomes peltate after its inception. One ovule is initiated at the adaxial portion (Querzone). The stigma becomes broad and flat, lobing at its margins. A slight outgrowth develops at the abaxial wall of the carpel. The floral apex has a two-layered tunica. The primordia of the stamens, carpels, and ovules arise by periclinal divisions in the second layer. Procambial development is acropetal following closely primordial inception. Each appendage, including the ovule, receives one procambial strand. The outgrowths of the connective and the carpel lack procambium.

透明的，未血管化的鞘包围成熟时的一部分花序。虽然类似于主轴的附属物，但在早期个体发育过程中，它发展为花序下方的更新生长顶点的预防。两个花在花序轴上发育，彼此相对。在每个花芽上以acropetal序列开始可育附属物。第一个形成，在中间位置，是两个雄蕊，在鞋面之前的下部。每个雄蕊发育出两个双孢子囊，由广泛的结缔组织隔开。在分化阶段，在结缔组织尖端附近略微背面开始背侧向外生长。这种生长似乎与Potamogeton densus中的类似生长同源，但与Potamogeton花的无菌附属物不同，一些作者将其错误地解释为结缔组织生长。每个心皮都是一个径向原基，在它诞生后变成盾状。在近轴部分（Querzone）开始一个胚珠。柱头变得宽而扁平，在其边缘呈裂片状。在心皮的远轴壁上出现轻微的生长。花卉顶点有一层两层的中膜。雄蕊，心皮和胚珠的原基由第二层中的周缘分裂产生。在原始的初始阶段之后，委托人的发展是一致的。每个附属物，包括胚珠，都接受一个原始链。结缔组织和心皮的生长缺乏原则。
