“…Relative to the inferred common ancestor of Cabombaceae and Nymphaeaceae, the perianth was reduced from more than two whorls to two whorls in Cabombaceae, and in Cabomba the androecium was reduced to one whorl with stamens in double positions. Anthesis lasts for two days in both Cabomba, which is insect pollinated, and Brasenia, which is wind pollinated (Schneider & Jeter, 1982;Osborn & Schneider, 1988;Taylor & Williams, 2009;Lima & al. 2014).…”

New morphological and phylogenetic data prompt us to present an updated review of floral morphology and its evolution in the basal ANITA grade of living angiosperms, Chloranthaceae, and Ceratophyllum. Floral phyllotaxis is complex whorled in Nymphaeales and spiral in Amborella and Austrobaileyales. It is unresolved whether phyllotaxis was ancestrally whorled or spiral, but if it was whorled, the whorls were trimerous. The flowers are probably ancestrally bisexual because in most families with unisexual flowers these flowers exhibit rudiments of the opposite sex. Carpels are largely ascidiate and the closure line is short, either transverse or longitudinal. A style is usually absent or, if present, generally short and not plicate. Angiospermy (carpel sealing) is by secretion, rather than postgenital fusion, except in large‐flowered Nymphaeales and in Illicium, correlated with unusual fruits. Carpels with a single, median, pendent ovule are probably plesiomorphic. Chloranth‐ aceae and Ceratophyllaceae have an unsettled phylogenetic position, but in some phylogenetic analyses they form a clade, which may be sister to the remaining mesangiosperms (Magnoliidae, monocots, eudicots). This position is supported by their carpel characters, which are similar to those of the ANITA grade and different from those of most other mesangiosperms.

RESUMO -Plântulas e diásporos são de extrema importância na recolonização de ambientes, contribuindo para a estabilização de áreas inundadas. Inexistem dados sistematizados sobre sementes, diásporos e plântulas de espécies de macrófitas que habitam áreas sazonalmente inundáveis do Pantanal. Objetivou-se desenvolver um guia com descrições morfológicas de plântulas, diásporos e sementes, assim como da estratégia de propagação vegetativa de macrófitas, inéditas para algumas espécies. Coletaram-se plântulas, diásporos e sementes em lagoas da subregião do Abobral/Pantanal. Pranchas contendo 24 espécies (14 famílias) foram elaboradas incluindo dados morfológicos e taxonômicos. As famílias e espécies descritas foram: todas as formas de vida. Algumas espécies apresentam propagação vegetativa (estolão, fragmentação, rizomas e brotação), outras apresentaram somente frutos. Palavras-chave: atlas, bancos de sementes, diásporo, guiaABSTRACT -Seedlings and seeds of aquatic macrophytes from ponds of the Pantanal of Mato Grosso do Sul. Seeds and seedlings are important for re-colonization and stabilize flooded areas. Currently, no systematized data is available for seedlings, seeds, and other diaspores of aquatic macrophyte species from seasonally flooded areas of the Pantanal. We developed a guide describing the morphology and the propagation strategies of diaspores and seedlings, some of which are described for the first time. Plants, seedlings and seeds were collected in ponds from the Pantanal subregion called Abobral. Plates include morphological and taxonomic data of 24 species, distributed in 14 families: Alismataceae (3 spp.), Araceae (1), Polygonaceae (3), Pontederiaceae (3), Cyperaceae (1), Lentibulariaceae (2), Nymphaeaceae (3), Onagraceae (2), Cabombaceae (1), Cannaceae (1), Hydrocharitaceae (1), Marantaceae (1), Plantaginaceae (1) and Rubiaceae (1). This sampling contemplates all life forms of macrophytes. While some species presented mainly vegetative propagation, such as stolon, fragmentation and sprouting, others also developed fruits.
