The present study analyzed taxa of the family Cabombaceae occurring in the state of Ceará. Only Cabomba species was represented, with C. aquatica and C. haynesii recorded in the state. Populations occur in permanent and temporary lentic environments, such as lagoons and shores of lotic systems. This work presents taxon identification keys, morphological descriptions, illustrations, comments and geographic distribution data.

The semiarid region of northeastern Brazil possesses a set of wetlands characterized by hydrographic basins with deficient drainage networks, a few large and permanent lotic systems and several permanent and temporary lagoons. Aquatic plants are widely distributed in these wetlands and the present study aims to determine if those of Ceará state have similar species compositions and differences in species richness. We hypothesized that lentic ecosystems would have more species and different growth forms of aquatic angiosperms than lotic ecosystems. A total of 1619 records of aquatic angiosperms in 43 wetland areas were analysed. The most representative families were Cyperaceae, Poaceae, Fabaceae, Alismataceae, Malvaceae, Nymphaeaceae and Pontederiaceae. Most of the species are helophytes and bottom-rooted emergent hydrophytes. Permanent lentic ecosystems had the highest number of exclusive species (27.85 %), followed by temporary lentic ecosystems (20.54 %). Contrary to our hypothesis, the different aquatic ecosystems were found to possess distinct species compositions and different proportions of growth forms, and all wetland types contributed to the macrophyte richness of the study area, although they differ in species richness. Therefore, conservation plans for the native aquatic macrophyte biota should include all wetland ecosystems in the semiarid state of Ceará.

Ceará state holds the second largest wetland extension in Northeastern Brazil and, thus far, there have been taxonomic studies developed about aquatic macrophytes richness for the clades of Monocots and Nymphaeales, and of two Eudicot families only. In this context, the present study is a synopsis of the aquatic representatives of Eudicotyledons and Ceratophyllaceae in Ceará state, providing further information about the biodiversity of aquatic ecosystems in the Brazilian semiarid. We present an updated survey based on material deposited at the EAC, IPA, R and RB herbaria and on images from digital platforms, including diagnostic descriptions, identification keys, photographs and comments about geographic distribution. We recorded 28 families, 43 genera and 82 species. The most representative families were Lentibulariaceae (12 spp.), Malvaceae (9 spp.), Plantaginaceae (9 spp.), Fabaceae (8 spp.) and Onagraceae (7 spp.), whilst Ceratophyllaceae was represented by one species only. Helophytes were the predominant growth form (64%), followed by the bottom-rooted emergent hydrophytes (20%), and Podostemaceae was the only family represented by haptophytes (4 spp.).
