First record of the rare Dyckia racemosa Baker (Bromeliaceae) in Maranhão state (northeastern Brazil), with an update on the species description, geographic distribution, and conservation status

Abstract

Dyckia racemosa is a Bromeliaceae species known from only three collections near Serra Geral, Central Brazil. In this study, the area of occurrence of the species is reported to extend to a Cerrado area in Maranhão state, northeastern Brazil. Digital collections from Brazilian and international herbaria were consulted. The species original description is complemented herein with illustrations and information on the species phenology, ecology, and conservation status. The discovery of D. racemosa in Maranhão demonstrates the importance of floristic studies and the need for further research of this nature in that Brazilian state.

Geographic range extension of Rapatea paludosa Aubl. (Rapateaceae) to Maranhão state, northeastern Brazil

“…The conservation of the remaining forest areas in Maranhão is of utmost importance since successive anthropic impacts could compromise the existing natural areas, leading to in the disappearance of species, or even taxa unknown to science (Koch and Araújo-Silva 2014;Rodrigues et al 2017). As observed for R. paludosa, the conservation of forest fragments and systematic floristic surveys has resulted in new records for the flora of Maranhão and the filling of some knowledge gaps (Koch and Araújo-Silva 2014;Ferreira et al 2017Ferreira et al , 2018Guarçoni et al 2018aGuarçoni et al , 2018bSilva Junior et al 2018…”

Implantação Do Herbário Do Curso De Ciências Naturais De Codó Prof. Deusiano Bandeira De Almeida (Henac) – Relato De Caso

“…O nome do Herbário é uma homenagem ao professor Deusiano Bandeira de Almeida por seu trabalho junto à comunidade do município de Caxias, onde esteve à frente do Departamento de Ciências Naturais do CESC/UEMA. Outras iniciativas de implementação de herbários vêm sendo realizadas como o herbário BMA -UFMA/Bacabal (GUARÇONI et al 2018); herbário Mandevilla do Campus I do UNIPAM (DIAS; BITAR 2013) e o herbário FIG, no Câmpus Medianeira da UTFPR (CIELO-FILHO et al 2016).…”

New occurrences of small aquatic duckweeds (Araceae, Lemnoideae) in Maranhão state, northeastern Brazil

“…Despite this, Maranhão has been little studied in floristic surveys. Recent studies have demonstrated several new species records for the flora of the state, indicating the need for further botanical surveys (Ferreira et al 2017;Ferreira et al 2018;Guarçoni et al 2018aGuarçoni et al , 2018bSilva Junior et al 2018).…”
