Encyclia inopinata (Orchidaceae, Laeliinae) a new species from Mexico
A new species of Encyclia from Mexico, Encyclia inopinata, is described and illustrated. This species is similar to Encyclia diota but it can be distinguished by its usually more robust plants with 2-3 leaves per pseudobulb and its flowers with longer and narrower sepals (1.8±0.1 × 0.63±0.03 cm in Encyclia inopinata versus 1.48 ±0.14 × 0.65±0.06 cm in Encyclia diota) and petals (1.7±0.05 × 0.59...
متن کاملOutcomes of Extensive Hybridization and Introgression in Epidendrum (Orchidaceae): Can We Rely on Species Boundaries?
Hybridization has the potential to contribute to phenotypic and genetic variation and can be a major evolutionary mechanism. However, when hybridization is extensive it can also lead to the blurring of species boundaries and the emergence of cryptic species (i.e., two or more species not distinguishable morphologically). In this study, we address this hypothesis in Epidendrum, the largest Neotr...
متن کاملAn Architectural Tale of the Two Cities
A comparative study of the corresponding styles of Western and Iranian modern architecture has hardly ever been carried out in detail. This paper aims to sketch out an outline for such an investigation and to present a summary of empirical evidence accompanied by field observations to elaborate the ongoing trend of relationship between architectural styles in Iran and that of the West. This is ...
متن کاملAnalysis of genetic diversity of Laeliinae (Orchidaceae) in the State of Sergipe using ISSR markers.
The Orchidaceae represent one of the largest and most diverse families on the planet. However, this family is constantly threatened by predators and by the advancement of urban centers over its natural habitats. The objective of this study was to use inter-simple sequence repeat markers to evaluate the genetic diversity between orchid accessions of the Laeliinae subtribe, which comprise part of...
متن کاملInterploidy hybridization in sympatric zones: the formation of Epidendrum fulgens × E. puniceoluteum hybrids (Epidendroideae, Orchidaceae)
Interspecific hybridization is a primary cause of extensive morphological and chromosomal variation and plays an important role in plant species diversification. However, the role of interploidal hybridization in the formation of hybrid swarms is less clear. Epidendrum encompasses wide variation in chromosome number and lacks strong premating barriers, making the genus a good model for clarifyi...
