Resumo: | Masdevallia coccinea and the Masdevallia ignea “banderitas” are ornamental orchids which are very prized by amateur farmers and collectors. In Colombia, the harvest pressure on these species has been enormous and few natural populations survive in the departments of Boyacá (Arcabuco of Berlin Páramo, Duitama) and Santander (between Málaga and Bucaramanga), in which these populations are reduced and of difficult access. For this reason these species are in the II appendix of CITES. However, little is known on their reproductive biology, floral biology and pollination and the literature about this is incomplete. Under this framework, the goal of the project was to study the morphology and morphometry of M. coccinea and M. ignea (Pleurothallidinae) under semicultivation conditions in the Villa Rosa farm located in the Municipality of Guasca, Cundinamarca (Colombia). The floral morphology was analyzed by digital photography, morphometry and Scanning Electron Microscope. The main results were differences in color and length of dorsal and lateral sepals between M. coccinea (X = 53.0 mm s = 7.4 mm and X = 44.4 mm and s = 8.3 mm) and M. ignea (X = 34 mm s = 7.7 mm and X = 31.5 mm and s = 6.1 mm). These parts were longest in M. coccinea in contrast to M. ignea. However the lip was longest in M. ignea (X = 7.1 mm y s = 0.6 mm). On the other hand both species had lip articulated to the column but without rewards as nectar and osmophores. |

En Colombia, la presión de colecta sobre estas especies ha sido enorme y pocas poblaciones naturales sobreviven en los departamentos de Boyacá (Arcabuco, Páramo de Berlín, Duitama) y Santander (entre Málaga y Bucaramanga), estas poblaciones son reducidas y de difícil acceso; razón por la cual se encuentran en el apéndice II de CITES. Poco se sabe sobre su biología reproductiva, sistema reproductivo y polinización y parte de lo que consta en la literatura es incompleto. En este marco el objetivo general del trabajo fue estudiar la morfología y morfometría floral de M. coccinea y M. ignea en condiciones de semicultivo al aire libre en la finca Villa Rosa ubicada en el municipio de Guasca, Cundinamarca, para lo cual se realizó fotografía digital, pruebas histoquímicas, morfometría y Microscopía Electrónica de Barrido. Los resultados principales de la morfometría mostraron que los sépalos dorsal y lateral fueron más largos en M. coccinea (X = 53,0 mm s = 7,4 mm y X = 44,4 mm y s = 8,3 mm) en comparación a M. ignea (X = 34 mm s = 7,7 mm y X = 31,5 mm y s = 6,1 mm), pero las coloraciones de las partes florales de esta última fueron más intensas y su labelo fue más largo (X = 7,1 mm y s = 0,6 mm). En las dos especies el labelo estuvo articulado a la columna y no se encontró presencia de glándulas con estructuras secretoras como nectarios ni osmóforos.application/pdfspaActa Biológica Colombiana.
