A new species of Andinia in subgenus Andinia from Tingo María National Park is described, illustrated and compared to the most similar species pair.  Andinia tingomariana is distinguished by unguiculate, reniform, ciliate petals, a longer column without the terminal dilation and a trilobed, ciliate lip in which the narrow, semi-auriculate lateral lobes project upward around the column, adnate in the middle, creating a furrowed surface. The floral morphology of the new species is compared to that of the phylogenetically unrelated Salpistele group of Stelis and possible convergent evolution of pollination syndromes is discussed. Finally, the first confirmed locality of A. schizopogon is reported and a preliminary list of Andinia species in Peru is provided.

Two new Andinia species are described, A. barba-caprina and A. crassipetala, both found during a botanical expedition to the montane forests of the Central Cordillera of the Peruvian Andes. They are compared with morphologically similar species, and Lankester Composite Dissection Plates (LCDP) are provided. Andinia barba-caprina is more similar to A. tingomariana but is distinguished by having obovate sepals with sparsely erose margins and the lip with narrowly obtuse, short basal lobes and a group of large hairs on the abaxial surface. Andinia crassipetala is distinguished from the two most similar species, A. hernandoi Est.Domínguez & S.Vieira-Uribe and A. persimilis (Luer & Sijm) Karremans & S.Vieira-Uribe for having thick, deltate and obtuse petals.

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.

Comparettia bennettii, a previously known species from Peru and Bolivia, is here recorded in the premontane forests of southeastern Ecuador. We provide a Lankester Composite Digital Plate (LCDP), photos, taxonomic comments, and an updated description of the species.
