“…The rapateacean flora of these four states is relatively rich, possessing all the nine genera and 36 from the 40 species recorded for Brazil (Rodrigues and Flores 2010;BFG 2015;Rodrigues 2015;Barbosa-Silva et al 2016). On the other hand, for the entirely extra-Guianan states of northern Brazil (Acre, Rondônia, and Tocantins; Fig.…”

“…However, even though floristic works for Rapateaceae are available for Venezuela, Colombia and the Guianas (Maguire 1958;1965;1982;Boom 1997;Berry 2004;2008;Funk et al 2007;Aymard and Arellano-Peña 2016;Rodrigues and Flores 2017), studies in adjacent areas in Brazil are relatively scarce (Maguire 1979;Forzza and Costa 2005;Rodrigues and Flores 2010;Rodrigues 2015;Barbosa-Silva et al 2016;Praia et al 2016). The knowledge about the biodiversity of the state of Rondônia is still incomplete (Carleial and Bigio 2014), including its rapateacean flora.…”

Generic additions to the Rapateaceae of Rondônia, Brazil

Rapateaceae is a monocot family centered in the Guiana Shield region of South America. This article reports four generic additions to the Rapateaceae of Rondônia, a state in northern Brazil. Cephalostemon gracilis (Poepp. & Endl.) R.H.Schomb., Duckea cyperaceoidea (Ducke) Maguire, Monotrema xyridoides Gleason, and Schoenocephalium cucullatum Maguire were recorded in lowland savannas and open white-sand ecosystems in the state. These findings extend significantly the known diversity of the Rapateaceae taxa occurring in Rondônia, and represent an extension of their geographical distribution to a Brazilian state with no part of its territory in the Guiana Shield.

“…These additions to Neotropical Selaginella yield the 100 species estimated by Valdespino (2015, 2016) for Venezuela and raises the number of native Brazilian taxa to 84, including S. psittacorhyncha and the recently recorded S. anaclasta Alston ex Crabbe & Jermy in Serra do Aracá, Brazil (Barbosa-Silva et al 2016), based on Labiak et al . 5639 (NY!).…”

Novel fern- and centipede-like Selaginella (Selaginellaceae) species and a new combination from South America

Valdespino¹

2017

View full text Add to dashboard Cite

Two new Selaginella species (i.e. S. altheae Valdespino and S. squamulosa Valdespino) and a novel combination [i.e. S. philipsonii (Jermy & Rankin) Valdespino] from South America are proposed. Descriptions, illustrations (line drawings and scanning electron micrographs, SEM, images), discussion on taxonomic affinities and information on habitat, distribution and phenology, as well as on conservation status are provided for each. Selaginella altheae is morphologically similar to species with erect, fern-like habit placed in the “Selaginella flabellata (L.) Spring group” as defined by Hieronymus, while S. squamulosa is allied to a species assembly with centipede-like habit here informally termed the “Selaginella vernicosa Baker group;” whereas S. philipsonii with its moss-like habit may be associated with species in the “Selaginella jungermannioides (Gaudich.) Spring group” or those centered on S. ovifolia Baker. All taxa here proposed are classified in subg. Stachygynandrum.

“…Entretanto, mesmo considerando a incompletude do conhecimento florístico na bacia amazônica (Hopkins 2007), especialmente em áreas remotas , muitas adições têm sido registradas em razão de recentes levantamentos na região (Rodrigues & Flores 2010;Medeiros et al 2014;Carleial & Bigio 2014;Sobral et al 2015;Costa et al 2016;Barbosa-Silva et al 2016).…”

ResumoO conhecimento sobre a flora da Amazônia brasileira é bastante incompleto e muitas áreas são ainda botanicamente pouco exploradas. Este trabalho reporta novas ocorrências de angiospermas para Roraima, provenientes de duas unidades de conservação no sudoeste do estado, o Parque Nacional Serra da Mocidade e a Estação Ecológica do Niquiá. Foram encontrados novos registros para quatro gêneros e 23 espécies pertencentes a 15 famílias de angiospermas. Leguminosae apresentou o maior número de novos registros, com cinco espécies. Os resultados trouxeram um acréscimo de 0,75% à flora de angiospermas em Roraima, ressaltando-se a necessidade de ampliação do esforço de coleta em todo o estado. Palavras-chave: Amazônia, distribuição geográfica, flora, unidades de conservação. AbstractKnowledge of the flora of the Brazilian Amazon is very incomplete and many areas are still botanically unexplored. This work reports new records of angiosperms to Roraima from two conservation units in the southwest of the state, the Serra da Mocidade National Park and Niquiá Ecological Station. New records for four genera and 23 species belonging to 15 angiosperm families were found. Leguminosae had the highest number of new records, with five species. The results brought an increase of 0.75% to the angiosperm flora in Roraima, highlighting the need to expand the collection effort throughout the state.
