A new tall and exceptional species of Lepanthes from north-west Ecuador (Orchidaceae: Pleurothallidinae)
(Lankester Botanical Garden, 2020) Luis E. Baquero; Marco F. Monteros
A new and spectacular species of Lepanthes from north-west Ecuador is presented here. Lepanthes tulcanensis belongs to the Marsipanthes subgenus and is similar to L. niesseniae in the same subgenus, with an inflorescence that does not reach the tip of the leaves, and flowers with shallower synsepal compared to the rest of the species in the subgenus. Nevertheless, the plants of L. tulcanensis are, by far, the largest among the species of the subgenus and aming the largest in the genus.

PLEUROTHALLIS MARKGRUINII, A NEW PLEUROTHALLIDINAE(ORCHIDACEAE) FROM NORTHWESTERN ECUADOR
(Royal Botanic Garden Edinburgh, 2024) Luis E. Baquero; Marco F. Monteros; Gabriel A. Iturralde; Marco M. Jiménez; Raul Dueñas
Pleurothallis markgruinii, a particularly tall species for the genus, is described as new to science and an illustration provided. The new species is most similar to Pleurothallis gargantua and shares with that species its large size, reaching 1 m tall, but differs in the much smaller flowers with a deeply concave dorsal sepal, narrower petals, and a synsepal with strongly revolute margins that form an elongated, triangular shape. Comprehensive field research has shown Pleurothallis markgruinii to have a restricted geographical range in the northwest Andes of Ecuador, and it is assessed as Critically Endangered. Pleurothallis markgruinii, una especie con plantas particularmente largas dentro del género se describe e ilustra aquí como nueva para la ciencia. La nueva especie es similar a Pleurothallis gargantua y comparte con esta las grandes plantas que alcanzan 1 m en longitud, pero se diferencia en las flores mucho más pequeñas con el sépalo dorsal muy cóncavo, pétalos más estrechos, y un sinsépalo con márgenes fuertemente revolutos que le dan una forma alargada y triangular. Investigación de campo exhaustiva muestra que Pleurothallis markgruinii tiene una distribución restringida, al noroeste de los Andes en Ecuador y es evaluada como en peligro crítico.
Three new endemic species of Lepanthes (Orchidaceae, Pleurothallidinae) from the highlands of Ecuador
(Pensoft Publishers, 2021) Francisco Tobar Suárez; María Fernanda López; María José Gavilanes; Marco F. Monteros; Tatiana Santander García; Catherine H. Graham
Three new species of Lepanthes from Ecuador are described and illustrated. These additions to the Ecuadorean flora were recorded in evergreen montane forest and páramo as part of three different research projects conducted during the last five years (2016-2021). Lepanthesoro-lojaensis was discovered in the southwest of El Oro province and is similar to L.jimburae, differing mainly in the much smaller plants, inflorescences and floral parts. Lepanthesmicroprosartima from the western slopes of Pichincha volcano in northern Ecuador resembles L.obandoi but differs in the coloration of the leaves, the inflorescence that are shorter than the leaves and the smaller floral appendix. Lepanthescaranqui, found in eastern Pichincha and Imbabura, is most similar to L.pachychila but differs from it in its much larger plants and different shape of the petals and the floral appendix. Preliminary assessments of the conservation status of the three taxonomic novelties are provided, using the IUCN Red List Categories and Criteria.
