Encyclia sclerocladia (Orchidaceae: Laeliinae) Revisited: A New Name, its Phylogenetic Position, and an Annotated Checklist of Peruvian Encyclia.

Abstract

Abstract—The identity of Epidendrum sclerocladium, currently referable to Encyclia, is clarified with the recent collection of material unambiguously referable to this entity. In addition, we provide a new name in Encyclia for this taxon, E. rhizomatosa Tamayo-Cen, Carnevali & G.A.Romero, because the current combination, E. sclerocladia (Lindl. ex Rchb.f.) Hoehne, is based upon the later homonym Epidendrum sclerocladium Lindl. ex Rchb.f. This name is predated by Epidendrum sclerocladium Lindley as we argue that Lindley validly published the name in a horticultural catalogue, a nomenclatural issue herein discussed. Furthermore, because the vegetative portions of the plants were unknown until recently, we provide an epitype to supplement the holotype for the unequivocal identification of the species. A preliminary assessment of its conservation status and phylogenetic relationships are presented. Encyclia thrombodes is discussed and it is concluded that no known plants are referable to this entity at this time. A lectotype is proposed for Epidendrum cyperifolium because the holotype was destroyed. Finally, we provide an annotated checklist of the Encyclia species known to occur in Peru.

Encyclia naranjapatensis Dodson (Orchidaceae), a new record for the Peruvian flora

“…This species has been recorded from several departments of Peru (e.g., San Martín, Loreto, Huánuco, and Pasco) and is easily differentiated from E. naranjapatensis by its plants up to 35 cm tall (vs. 75 cm tall), oblong-lanceolate sepals, 12-15 mm long (vs. narrowly obovate, 18 mm long), oblongoblanceolate petals, 11-14 mm long (vs. spatulate-obovate, 18-20 mm long), and the central lobe of the lip ovate to sub-orbicular, with a conspicuous apiculum (vs. sub-quadrangular, emarginate, not apiculate) (Figure 3). The picture shown by Valenzuela Gamarra et al (2022) corresponds to a dull maroon form of E. chloroleuca (Tamayo-Cen et al 2020). The polymorphic colors in flowers of the same species can be driven by the presence of anthocyanin and carotenoid pigments in the flowers (Narbona et al 2014).…”
