讨论:Diversity and Classification of Flowering Plants:基部类群

有关本书莼菜科描述的问题

书中原文对莼菜科的描述是这个样子的：
The Cabombaceae consist of aquatic herbs. The underground stems are rhizomatous, which give rise to elongate leafy shoots.The stem vasculature is atactostelic. The leaves are dimorphic, floating or submersed, exstipulate, spiral, opposite, or whorled, simple and undivided or highly divided into numerous segments.(此处的描述应该基于具体的种，并且后面对于叶分裂的描述也显然指代不清) The inflorescence consists of a solitary, emergent flower. Flowers are bisexual, actinomorphic, and hypogynous.The perianth is dichlamydeous (differentiated into calyx and corolla), the parts whorled. The calyx consists of 3 [2 or 4] aposepalous sepals. The corolla consists of 3 [2 or 4] apopetalous petals. Stamens are 3 or 6 (in Cabomba) or 12-many (in Brasenia); the filaments are somewhat laminar The gynoecium is apocarpous, with a superior ovary, and 2–18 [1] carpels; placentation is parietal; ovules are anatropous, bitegmic, and 2–3 [1] per carpel; styles are terminal or decurrent along the carpel. The fruit unit is a coriaceous follicle.
其中我感到困惑的部分采用了加粗斜体表示，仅仅参考FOC内容有点片面，也感谢布丁在原界面的补充！--Imagine（留言） 2025年9月4日 (四) 14:55 (CST)
