Whereas knowledge on the mechanisms and consequences of sexual reproduction in the Orchidaceae increases rapidly, the role of asexual reproduction on lineage diversification and speciation remains as one of the most challenging questions to be answered. In this context the 'Zygopetalum maculatum' species complex emerges as a potential model for study. This group is unique among orchids fo…
Polyploidy affects biological interactions and, therefore, may determine the reproductive isolation of cytotypes. Mycorrhiza is a key interaction for all orchid species. The spatial distribution of mycorrhizal fungi may determine the geographical distribution of orchid populations and the spatial isolation of individuals within populations. However, we have little knowledge on the role of…
The genus Brasiliorchis is a monophyletic group with 14 species recently segregated of Maxillaria. Although morphologically easy to recognize, Brasiliorchis contains some of the most taxonomically difficult groups of Brazilian orchids, one of them being the Brasiliorchis gracilis complex. These are small-median size orchids found in high altitudes of the Serra do Mar and Serra da Mantique…
