BackgroundThe Araguaia River basin runs through the states of Goiás, Mato Grosso, Tocantins, and Pará, covering 373,000 Km2, mostly within the Brazilian Cerrado. The region has a wide variety of wetlands. The climate is characterized by high temperatures and strongly seasonal precipitation. There are two well defined seasons: the dry season (winter-spring) and the rainy season (summer- fall). The Araguaia River basin is dominated by plinthosoils that are found in low flat areas, poorly drained and prone to flooding, yielding wetland habitats of high plant diversity. Since the 1970s, human activities have led to reduction in both the diversity and area of wetlands. The construction of the Belém-Brasília highway and hydroelectric dams, as well as the expansion of agricultural and mining activities, have had major impacts on the region.New informationThe flora diversity data of the Araguaia River basin was developed through field work, herbarium research, and use of a database (Species Link). The resulting checklist of 162 aquatic and marshy monocotyledons from the Araguaia River basin represents 20 families and 50 genera. Cyperaceae (51 spp.), Poaceae (39 spp.), and Eriocaulaceae (16 spp.) are the most representative families. Life form analysis indicates that helophytes predominate (98 spp.; 60.5%). One hundred one species are native to tropical and/or subtropical America and twenty one are endemic to Brazil. Ninety-three species are new occurrences for the Araguaia River basin. Among them, three species are reported in the Brazilian Cerrado for the first time. This work contributes to the understanding of aquatic plant diversity in the Cerrado and other savanna-like vegetation physiognomies; environments and habitats poorly understood taxonomically and undercollected generally.

Objective: This study aimed to evaluate the cytotoxic activity of the extracts and fractions of Eriocaulon cinereum against HeLa and Vero cell lines,which represent cervical cancer and normal cells, respectively. In addition, a phytochemical screening was carried out to determine the chemicalconstituents in the extracts and the active fractions.Materials and Methods: The extracts of E. cinereum were obtained by ultrasound-assisted extraction method using n-hexane, ethyl acetate, andmethanol, successively. The active extract was fractionated using vacuum liquid chromatography with dichloromethane followed by ethyl acetate. Thecytotoxic activity was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay method and was measured using microplatereader at the wavelength 595 nm. The data were analyzed with PROBIT from SPSS 16 for Windows®. In addition, phytochemical screening wasperformed using standard procedures.Results: The cytotoxic evaluation of the extracts of E. cinereum showed that the ethyl acetate extract was the most active extract against HeLa cell linewith the half maximal inhibitory concentration (IC50) value of 580.07 μg/ml. The dichloromethane and ethyl acetate fractions from the active extractof E. cinereum exhibited cytotoxic activity against HeLa cell with the IC50 values of 466.61 μg/ml and 267.34 μg/ml, respectively. In addition, the ethylacetate fraction showed a low cytotoxic effect against Vero cell line. The phytochemical screening of the ethyl acetate fraction indicated the presenceof terpenoids and alkaloids.Conclusion: This finding revealed the anticancer potential of E. cinereum and warranted further investigation for the discovery of new anticanceragents from natural resources for cervical cancer.

“…The inclusion of D. ligulata in Eriocaulon is also confirmed by the aquatic habitat mentioned in Vellozo's (1829: 36) protologue. Oliveira & Bove (2015) indicated "plate 86 published in Florae fluminensis vol. 1, 1827" as lectotype of Eriocaulon ligulatum.…”

A reevaluation of the Dupatya (Eriocaulaceae) names proposed by Vellozo in the Florae fluminensis is presented. Based on analyses of Vellozo's text, plates, original material and protologues of all species of Eriocaulon and Paepalanthus originally assigned to Dupatya, we accept E. ligulatum and P. aequalis, while D. hirsuta is reduced into synonymy with E. kunthii. Lectotypes are proposed for names based on the original plates of Vellozo's work deposited at the Manuscript Section of the Rio de Janeiro National Library.
