A new <i>Specklinia</i> (Orchidaceae: Pleurothallidinae) from Costa Rica and Panama

Abstract

A new species of Specklinia from the Cordillera de Talamanca in southern Costa Rica and western Panama is described and illustrated. Specklinia absurda most closely resembles Specklinia fuegi. It differs from that species in the pendent, single flowered inflorescence, whitish yellow sepals with red-pink veins and yellow apex, red petals with translucent margins, pandurate-trilobed, unguiculate lip with a distinct papillose isthmus below the anterior lobe, and reniform, erose, erect lateral lobes, with a Y-shaped thickened, hirsutulous apical callus. The affinities of this species to other Specklinia species are discussed.

Genera Pleurothallidinarum: an updated phylogenetic overview of Pleurothallidinae

“…The proposed affinities are Acianthera (Ac), Dilomilis (Di), Lepanthes (Le), Masdevallia (Ma), Octomeria (Oc), Phloeophila (Ph), Pleurothallis (Pl), Restrepia (Re) and Specklinia (Sp); the oldest generic name is used here for the species within those clades (except Pleurothallis).

Lankesteriana, a new genus in the pleurothallidinae (orchidaceae)

“…at some point or another. A more extensive molecular phylogenetic analysis of Specklinia (Karremans et al unpublished), excludes the species here treated as Anathallis (Pupulin et al 2012, Bogarín et al 2013, Karremans et al 2013b, requiring the circumscription of those genera in the present manuscript. It becomes necessary as well to propose the systematic modifications required in order to attain monophyly within Anathallis, Specklinia, and Stelis and to propose a segregated generic concept for the A. barbulata and its close relatives.…”

“…Carib., 29. 1760. Although this genus has been traditionally accepted (Karremans et al 2013), it was greatly modified by and Pridgeon et al (2005). As such the genus was broadened from its classic definition (Luer 2009) to include several species groups before placed in Pleurothallis.…”

“…As such the genus was broadened from its classic definition (Luer 2009) to include several species groups before placed in Pleurothallis. Stelis in its broad sense was phylogenetically analyzed and extensively discussed by Karremans (2010) and Karremans et al (2013), and was proven largely monophyletic if the species of Pleurothallis subgen.

<I>Specklinia lugduno-batavae</I> (<I>Pleurothallidinae</I>: <I>Orchidaceae</I>), a new species in the <I>S. digitalis</I> group

“…(Luer 1986), the genus Specklinia Lindl. was re-established by Pridgeon & Chase (2001), and has ever since then, with some exceptions (Luer 2006), received general acceptance by the orchid community (Pridgeon 2005, Pupulin et al 2012, Bogarín et al 2013. Species in the genus are recognised by the tiny habit with ramicauls shorter than the leaf, obtuse petals, a ligulate lip, prominent column wings and naked pollinia that lack caudicles (Karremans 2014).…”
