Nomenclatural notes and new combinations on Anathallis and Specklinia (Orchidaceae)

Abstract

Even though many new combinations have been proposed for the genera Anathallis Barb.Rodr. and Specklinia Lindl., since their re-establishment in 2001, several Brazilian species bearing the characteristics of these genera were never transferred from Pleurothallis R.Br. sensu lato. In this work 17 Brazilian species formerly attributed to Pleurothallis are transferred to Anathallis (16 species) and Specklinia (one species). Also, several superfluous names created from double new combinations in the genera Anathallis and Specklinia are pointed out.

Laeliinae (Orchidaceae) do parque nacional do Caparaó, Estados do Espírito Santo e Minas Gerais, Brasil

“…Na sequencia, também foram listados os materiais provenientes de outras localidades e citados como material adicional. A distribuição geográfica das espécies foi baseada no material examinado e complementada com dados de literatura específica: Pabst & Dungs (1975, 1977 e Barros et al (2010). Em Orchidaceae, considerando que o limite entre o ovário e o pedicelo não é preciso na análise, optou-se pela tomada de medidas dessas estruturas em conjunto.…”

“…No Brasil ocorrem 32 espécies (Barros et al 2010 Erva epifítica. Pseudobulbo 1-3,5 × 0,4-0,6 cm, 1-2-foliado, fusiforme, revestido por bainhas paleáceas, fechadas, oblíquas, ápice truncado.…”

“…É uma das mais importantes famílias no Brasil, sendo que grande concentração de espécies ocorre na costa leste, na Floresta Atlântica. Nesse país, é registrada a ocorrência de 2.419 espécies e 235 gêneros (Barros et al 2010). Dentre as Orchidaceae neotropicais, destaca-se a tribo Epidendrae com 5.870 espécies (Chase et al 2003), a qual inclui as subtribos Bletiinae, Chysinae, Laeliinae, Pleurothallidinae e Ponerinae ( .…”

<I>Anathallis roseopapillosa</I> (Orchidaceae - Pleurothallidinae), a New Species from the Central Amazon Region

“…Anathallis fastigiata (Luer & Toscano) F. Barros & Barberena, a species described from Pará, Brazil, was not included because there is no material deposited in the visited herbaria, and although Luer and Toscano-de-Brito (2002) cite the holotype in the HUEFS, we could not locate it. As explained by Barros and Barberena (2010), according to the staff of this herbarium, apparently it was never deposited there.…”

“…The generic affiliation of the majority of the species of the subtribe Pleurothallidinae, originally placed in Pleurothallis Lindl., has been changed in recent years due to the use of molecular approaches Barros 2002Barros , 2003Barros and Rodrigues 2009;Luer 2006Luer , 2007Luer , 2009Chiron et al 2012). The studies of and Chiron et al (2012), using nuclear DNA sequences, showed that several infrageneric taxa previously proposed for Pleurothallis by Luer (1986) were not monophyletic groups.…”
