A new natural hybrid of broughtonia(orchidaceae) from Cuba

AbstractAt Cabo San Antonio (GuanahacabibesPeninsula), Cuba in 2004, a single specimen of Broughtoniaortgiesiana (Rchb.f.) Dressler, and a relatedspecies, Broughtoniacubensis (Lindl.) Cogn., were both observed in flower simultaneously. In 2006, fruits were observed on B. ortgiesiana, and nine years later (2015) we noted five young plants in anthesis that displayed floral characteristics common to both species. Given the time frame and the blend of floral traits, we conclude that these five plants are the result of a natural hybridization event between the two Broughtonia species the details of which are described here.

Riqueza de la familia orchidaceae en la zona de visitantes del Parque Nacional Cerro Azul Meámbar de Honduras

ResumenSe presentan las especies de orquídeas encontradas en la zona de visitas del Parque Nacional Cerro Azul Meámbar (Panacam), Comayagua, Honduras. A partir de las observaciones de orquídeas se generó una matriz de presencia-ausencia mensual basada en la floración observada de cada especie. En esta matriz se hizo un análisis de riqueza de especies usando el estimador jackknife de primer orden. Se agrupan los meses del año en función de la riqueza de las especies de orquídeas con flor para cada mes. Se registran 101 especies más de orquídeas para el parque y se predice la presencia de aproximadamente 140 en su zona de visitantes.

Abstract:A list of orchids found in the visitors zone of Parque Nacional Cerro Azul Meámbar, Comayagua, Honduras, is presented. A monthly absence- presence matrix was made for the orchids found with flowers of each species; with this matrix we made a richness analysis using the first order jackknife estimator. The months of the year were grouped in function of the orchid species in flower for each month. An additional 101 species of orchids are reported for the park, and 140 species are predicted for the visitor's zone.

A colorful new species of neooreophilus(orchidaceae: pleurothallidinae) from the eastern Andes of Colombia and Ecuador

Abstract:A new species of Neooreophilus from the eastern Andes of Colombia and Ecuador is described and illustrated. Neooreophiluschaoae is related to a group of species that includes N. cordilabius, N. chelosepalus and N. werneri characterized by having an obovate, pubescent dorsal sepal and spread or reflexed, non-pubescent lateral sepals ending with an apiculum. The new species can be distinguished by its narrowly triangular lateral sepals and its lip with lateral lobes not extending beyond the column. Notes about its natural habitat and conservation status are also given.

A new checklist of orchid species from Cuba

Abstract:In 2014, James D. Ackerman and collaborators published the last checklist of Cuban orchid species in the book, "Orchid Flora of the Greater Antilles". The aim of our study was to determine the current number of orchid species in Cuba and adjacent islands culminating in an updated checklist. We consulted numerous publications and reports, visited four herbaria, and refer to ongoing collaboration with leading specialists. A total of 91 genera and 312 species are documented. We provide comments on taxonomic status on noteworthy species.
