“…Earlier studies of shoot architecture and branching patterns in Ceratophyllum mainly covered two species, C. demersum and C. submersum. The present paper provides comparative SEM-based developmental data on three species of the genus (C. submersum, C. tanaiticum, and C. demersum) representing different clades revealed using molecular phylogenetics [30]. The aims of our study are further refinement of morphological interpretation of Ceratophyllum, analysis of developmental correlations and search of potential interspecific differences.…”

“…While the phylogenetic placement of Nymphaeales in the basal angiosperm grade is currently well-established, the relationships of Ceratophyllales are incompletely resolved [26][27][28]. Ceratophyllales, with the only extant family Ceratophyllaceae, the only extant genus Ceratophyllum (sometimes two genera are recognized [29]), and six species [30], is the smallest of the five primary lineages of mesangiosperms. Other mesangiosperm clades are eudicots, monocots, magnoliids, and Chloranthaceae.…”

“…Accurate scoring of each terminal group ultimately depends on morphological interpretation and is crucial for analyses of character evolution, especially for taxonomically isolated and ancient lineages. At the same time, such interpretation can be highly problematic, as in the gynoecium of Ceratophyllum ( Figures 1A–C ), an ancient aquatic genus of about six species with minute unisexual flowers and peculiar underwater pollination ( Les, 1986 ; Szalontai et al, 2018 ). Currently recognized as a distinct order, Ceratophyllales, Ceratophyllum has been described as a ‘rogue’ or ‘orphan’ taxon because of its problematic position in phylogenetic analyses ( One Thousand Plant Transcriptomes Initiative, 2019 ; Albert and Renner, 2020 ).…”

“…To explore the controversial interpretation of the gynoecium in Ceratophyllum as either monomerous (having a single carpel) or pseudomonomerous (superficially resembling the monomerous condition, but actually composed of at least two fused carpels), we investigated morphological variation in pistillate flowers of three species, C. demersum L., C. submersum L. and C. tanaiticum Sapjegin, which represent three of the four major clades within Ceratophyllum identified by molecular data ( Szalontai et al, 2018 ). Until now, all studies of flower development in Ceratophyllum using scanning electron microscopy (SEM) have concerned a single species, C. demersum .…”
