A new species of Octomeria from southern Ecuador was found during an investigation on the orchids of the Cordillera del Cóndor. Octomeria candidae is described and illustrated; likewise, information on its distribution, habitat and conservation status is provided. The new proposed taxon is morphologically similar to O. estrellensis, from which it differs by its creeping habit, the narrowly ovate, long-acuminate sepals and petals, and the yellow lip with an acute apex.

Pleurothallis minutilabia, a species unique in subsection Macrophyllae-Fasciculatae because of the minute, highly reduced lip, is described and compared to the most similar species in the subsection. It is also compared morphologically to Pleurothallis kaynagata from section Abortivae, to which P. minutilabia is not related, but which also possesses a highly reduced lip. The morphology of the flower of P. minutilabia is discussed briefly in relation to possible pollination mechanisms. The distribution, restricted to Zamora Chinchipe, southern Ecuador, and the conservation status are addressed. Key words / Palabras clave: cloud forest, Ecuador, labellar morphology, Pleurothallis, pollination

Barkeria uruapani, a new orchid species endemic to Michoacán, Mexico, is described and illustrated. Information on its distribution, habitat and conservation status is provided. The new species is also compared with B. barkeriola and B. uniflora, and an updated key to all Barkeria species is included. Diagnostic features of B. uruapani include the branching inflorescences with simultaneous anthesis, the elliptical-obovate lip with a large magenta spot, the revolute wings of the column and the lateral sepals forming an obtuse angle.

A new orchid species in Pleurothallis subsection Macrophyllae-Fasciculatae, is described and illustrated. It was discovered in semi-deciduous premontane forest from Southwestern Ecuador. The new species is named herein as Pleurothallis marioi; information about its distribution, habitat, phenology, and conservation status is provided. The new taxon is compared with P. acestrophylla, P. arctata, P. calamifolia, P. lemniscifolia, P. portillae, and P. subtilis, species to which it is morphologically similar.

A new orchid species in Stelis is described and illustrated. It was discovered in semi-deciduous montane forest in Southwestern Ecuador. The new species is named Stelis rostriformis. Information about its distribution, habitat, phenology, and conservation status is provided. The new taxon is a member of Crocodeilanthe, a group that has previously been considered as a different genus or as a subgenus of Pleurothallis, but the available evidence indicates that it turns out to be non-monophyletic. The new species is compared with other morphologically similar, such as S. batillacea, S. cyathiflora, S. galeata and S. gargantua. Additionally, Stelis sagittata is proposed as a new name for Pleurothallis jamesonii since the combination of it in Stelis proved be illegitimate because the earlier existence of Stelis jamesonii.

Lepanthes vere-aurum, a new species of the orchid subtribe Pleurothallidinae, discovered in Zamora Chinchipe province, southeast Ecuador, is described here. We compare L. vere-aurum to L. brenneri, the only similar species, from which it differs in having larger leaves and longer inflorescences. Also, L. vere-aurum has an obovate, concave, long-acuminate dorsal sepal and a concave appendix with a pubescent crest underneath and with a long, pubescent apex,versus a flat, triangular-ovate, acuminate dorsal sepal and a smaller appendix with a ciliate apex in L. brenneri. Some information about its phenology and ecology is additionally provided. Key Words: Cordillera del Cóndor, endangered orchid, Epidendroideae, Lepanthes brenneri, new orchid species

Abstract—A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5‐9.7 mm long, flower buds 3.5‐4 mm in diameter, and by the calyx lobes that are 2‐3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain.

Scrophularia dianatnejadii Ranjbar & Rahchamani, a new species from Tehran Province in northern Iran, is described and illustrated. It is closely related to S. amplexicaulis Benth. and shares with it some diagnostic morphological characters such as habit, plant indument, phyllotaxy, and corolla shape and color. Both species are placed in Scrophularia L. sect. Mimulopsis Boiss. Macro- and micromorphological characters of the two are examined and compared. Pollen morphology of these species is investigated using SEM. Detailed descriptions, illustrations, distribution maps, and conservation status of both species are provided.
