A SEM survey of seed, stem, stomata, andfruit characters was conducted to investigate patterns of infraspecific variability inRhipsalis baccifera. New and Old Worldseeds were analyzed to assess the taxonomicvalue of their morphological features andthe presence of gigas characters in polyploidversus diploid subspecies. The seeds aremussel-shaped and correspond to the Rhipsalis-type. Old World representatives haveprimarily oval seeds, whereas narrowly ovalto oval seeds are more common in NewWorld accessions. The seed coat is glossy,smooth, and without secondary sculpturing.The cell outline is slightly irregular with anoverall elongate to rectangular shape. Cellsize increases from the hilum-micropylarregion to the apical portion of the seed.Se...
