  Introduction and Aims. Anthurium is the largest genus of Araceae, with 950 species distributed in the neotropics. Despite the great diversity of the genus, the knowledge of its floral vasculature is based on observations in only two species, viz. A. denudatum and A. lhotzkyanum, with remarkable variation in vascular carpellary supply: carpels are either vascularized by ventral bundles alo…

• Abstract

  The use of various data sources in an integrated manner has facilitated the understanding of interspecific group limits, mainly in the Neotropical region with its great biodiversity and related evolutionary diversification processes. Epidendrum L. is the largest genus of orchids in the Neotropics; E. secundum and E. xanthinum, belong to the entitled "E. secundum complex" with disjoint dis…

• Abstract

  Anthurium comprises approximately 130 species in Brazil mainly circumscribed within A. sect. Pachyneurium and A. sect. Urospadix. Apart from those sections, A. sect. Tetraspermium is also important by the occurrence of its representatives - 50% of its species occur in Brazil. The infrafamiliar systematics is still discussed in Anthurium, especially due to circumscriptions based on morphol…

• Abstract

  Bulbophyllum Thouars, with 1879 espécies, is the second largest genus of angiosperms and is represented by six sections in the Neotropics. Within the sections, floral morphology varies probably due to environmental pressures and pollinators specificity. The aim of this study is to answer the following questions: a) Which of the floral morphological and anatomical characteristics vary due …

• Abstract

  Epidendrum Lindl. is the largest genus of orchids in the Neotropics; E. secundum and E. xanthinum belong to the entitled "E. secundum complex" and both species have disjoint distribution in the Espinhaço Range and Serra do Mar in Brazil. The taxonomic delimitation problems in the complex are due to the large polymorphism as the size and shape of flowers, resulting in discussion about the …

• Abstract

  Bulbophyllum Thouars is the second largest genus of Angiosperms and is divided in six sections in the neotropics. Floral morphology varies between the sections, probably due to environmental pressures and pollinator specificity. The aim of this is study is to answer the following questions: a) Are there floral morphoanatomical synapomorphies for Bulbophyllum sections Didactyle and Micrant…
