To elucidate the factors which control the flower phenotypic plasticity of Catasetum fimbriatum , studies focusing the floral development of the species were performed. The treatments were: high light intensity (1613 μmol.m -2 .s -1 ); low light intensity (454 μmol.m -2 .s -1 ) and mean light intensity (827 μmol.m -2 .s -1 ). The floral morphology and anatomy were analyzed to evaluate of the sequence of tissue development involved in the sexual differentiation. We found the presence of cell cluster with meristematic features in the ovaries and gynostemium of the male and female diclinous flowers. These are responsible for the definition of the sexual expression of the species, in the dependence of the environmental stimulus, related to the endogenous concentration of ethylene, allowing, consequently, the dedifferentiation and re-differentiation of those clusters in the sexual determination of the flowers. There were no anatomical differences in floral tissues in different treatments.

In Epidendrum, considered a monophyletic genus, diverse groups can be recognized by their similar vegetative and floral characteristics. The revision of one of these groups, the E. macrostachyum group, recognized by the monopodial habit, with sub-apical branching, apical, erect inflorescence, non-resupinate, fleshy flowers, and entire lip, embracing the column, pubescent at least at the base, has led to the description of several new species, including a new species from Colombia that is here described and illustrated. The species is similar to Epidendrum microrigidiflorum , but differs in the inflorescence (distichous, 6 flowered vs. racemose, 8-16 flowered), the shape (trullate vs. widely rhombic) and ornamentation of the lip (sericeous vs. minutely papillose), and the lack of calli on the disc of the lip (ecallose vs. bicallose). In addition, a key to the 41 species of the group is provided. rEsuMEn: En Epidendrum, siendo considerado un genero monofiletico, se pueden reconocer diversos grupos de especies con caracteristicas vegetativas y florales similares. La revision de uno de estos grupos, el grupo E. macrostachyum, el cual se reconoce por su habito monopodial con ramificaciones subapicales, inflorescencia apical, erecta y flores no resupinadas, carnosas con el labelo entero abrazando la columna y pubescente por lo menos en la base, ha permitido la descripcion de varias especies nuevas, entre ellas la nueva especie que se describe y se ilustra aqui. Es una especie colombiana similar a Epidendrum microrigidiflorum , sin embargo difiere por la inflorescencia (distica, 6 flores vs. racemosa, 8-16 flores), en la forma (trulado vs. anchamente rombico) y ornamentacion del labelo (densamente sericeo vs. diminutamente papiloso) y en la ausencia de callos en el disco del mismo (ecalloso vs. bicalloso).

Se caracterizo y se comparo la morfometria de las semillas de cuatro especies de vainillas colombianas ( Vanilla odorata , Vanilla calyculata , Vanilla oroana y Vanilla rivasii ). Las semillas colectadas a partir de frutos maduros fueron estudiadas por microscopia optica para caracterizar el color, la longitud y el ancho de las semillas. Ademas, por medio de microscopia electronica de barrido (MEB) se identificaron las caracteristicas de la superficie de la testa. Existieron diferencias significativas en la longitud, el ancho y en la relacion longitud/ ancho entre las especies. Vanilla oronana tuvo las semillas mas grandes (431 ± 17 μm de largo y 312 ± 27 μm de ancho) y difirio de las otras especies por presentar la coloracion parda en tono mas oscuro y por la presencia de protuberancias en la testa. Vanilla odorata fue la especie con semillas mas pequenas (310 ± 15 μm de longitud y 222 ± 18 μm de ancho) de color pardo claro. En general, las semillas presentaron la testa lisa y una forma elipsoide. Los caracteres evaluados en este trabajo podrian servir como marcadores taxonomicos en Vanilla y podrian explicar aspectos importantes de la biologia de las semillas de este genero.

In Cuba, there are 315 species of Orchidaceae family, approximately 32 % of these species are endemic. During 2012 and 2013 an endemic population of Tetramicra malpighiarum (Orchidaceae) was studied at the Desembarco del Granma National Park, Cuba. We determined the abundance of this species, life classes (immature and adult), phorophytes inhabited, vertical distribution (trunk, branches or twigs), solitary or aggregated growing, and its cardinal orientation on phorophytes. We found 254 individuals of T. malpighiarum distributed in 20 phorophytes. For the first time, were found individuals of T. malpighiarum grew on other five species of phorophytes, besides of Malpighia incana (Malpighiaceae) and Erythroxylum havanense (Erythroxylaceae). Of the total of individuals recorded, 69.3 % were adult and 93.7 % were growing on the twigs. The number of solitary individual and aggregated individuals was similar. The population shows a slight tendency to grow toward south and northwest orientations. This is the first study to describe the population ecology of T. malpighiarum , but it is recommended to conduct long-term genetic and demographic studies. These future studies should be explored the reproductive system (e.g., level of endogamy) and population genetic of this species endemic of Cuba in order to evaluate its permanency in the future.
在古巴，兰科植物有315种，其中约32%是特有的。2012年和2013年期间，在古巴格兰玛Desembarco del Granma国家公园对malpighiarum(兰科)特有种群进行了研究。测定了该树种的丰度、生活层(未成熟层和成虫层)、有生境的光生植物、垂直分布(树干、分枝或小枝)、单生或聚集生长及其在光生植物上的基本方位。在20个光合植物中发现了254个马尔匹氏螺旋体个体。除麻瓜科麻瓜属(Malpighia incana)和哈瓦那红瓜属(Erythroxylum havanense)外，还首次在其他5种光合植物上发现了麻瓜属的个体。在记录的个体中，69.3%为成虫，93.7%生长在树枝上。单独个体和聚集个体的数量相似。人口有向南和向西北方向轻微增长的趋势。这是第一次对马尔皮线虫种群生态学的研究，但建议进行长期的遗传和人口研究。今后的研究应探讨这种古巴特有物种的生殖系统(例如内婚制水平)和种群遗传，以便评价其今后的持久性。
