Clonal growth and dispersal potential of Leiothrix flagellaris Ruhland (Eriocaulaceae) in the rocky grasslands of Southeastern Brazil

Abstract: -(Clonal growth and dispersal potential of Leiothrix flagellaris Ruhland (Eriocaulaceae) in the rocky grasslands of Southeastern Brazil). Leiothrix flagellaris is a small clonal plant that grows in sandy/rocky, nutrient poor soils in the rocky grasslands ("campos rupestres") of southeastern Brazil. In the rainy season most of their flower heads differentiate into small rosettes, produced by pseudovivipary, and connected to the mother-plant by flexible, elongated stalks that can reach up to 90cm. Most of these … Show more

“…Benites et al 2007, Ribeiro et al 2007). However, most mountain biodiversity research in Brazil is concentrated in elevations within the "cerrado" biome ("campos rupestres"; e.g., Coelho et al 2007, Figueira & Del Sarto 2007, Medina & Fernandes 2007, Velten & Garcia 2007, and in the "campos de altitude" of the Atlantic Rainforest biome (Martinelli 1996, Porembski et al 1998, Safford 1999, Safford & Martinelli 2000, Caiafa & Silva 2007, Ribeiro et al 2007). This pattern repeats itself in the present special issue: none of the studies published here are set in the Brazilian Amazon, and most concentrate within the "cerrado" and the Atlantic forest biomes.…”

“…Em S. chrysanthus foram observadas rosetas reprodutivas em várias classes de diâmetro, diferente do descrito para a monocárpica A. polyanthus (Castellani et al 2001), onde a chance de reprodução aumentava com o tamanho da planta. Um tamanho mínimo para se reproduzir também foi registrado para outras Eriocaulaceae, como L. fl agellaris Ruhland (Figueira & Del Sarto 2007), L. curvifolia var. lanuginosa e L. crassifolia (Coelho et al 2007).…”

“…Para essa família é observada a pseudoviviparidade, presente no gênero Leiothrix (Coelho et al 2005;2008a;b;Figueira & Del Sarto 2007), e brotamento de rosetas a partir de rizomas, observado em espécies de Leiothrix (Coelho et al 2007;2008a;b) e Syngonanthus (Scatena et al 1997;Schmidt et al 2007). A pseudoviviparidade em Leiothrix tem sido caracterizada como uma estratégia do tipo guerrilha, enquanto que a rizomatosa, do tipo falangeal (Coelho et al 2007;2008a;b;Figueira & Del Sarto 2007).…”

“…Stephanophyllum (Körnicke) Ruhland. In these groups, viable plantlets are regularly produced on decumbent peduncles, as carefully studied in Leiothrix spiralis (Bongard) Ruhland (Coelho et al 2005(Coelho et al , 2006, and L. flagellaris (Guillemin) Ruhland (Figueira & Del Sarto 2007). According to Giulietti (1984), seed production is much reduced in these pseudoviviparous species.…”
