Chromatographic and spectrophotometric methods were used to identify the floral anthocyanins of Broughtonia domingensis, B. negrilensis, B. sanguinea, Brassotonia ‘John Miller,’ Diabroughtonia, Brassavola nodosa, Cattleyopsis lindenii , and Cattleytonia ‘Rosy Jewell’ for the purpose of establishing chemotaxonomic relationships and inheritance patterns. Flowers of Brassavola nodosa were found to contain raphanusin C, an anthocyanin not present in Cattleyopsis lindenii or in any of the Broughtonia species and hybrids. Pelanin is present in flowers of Broughtonia domingensis and B. negrilensis , but not in those of B. sanguinea . Raphanusin B, raphanusin D, and pelargonidin‐3‐glucoside, 5‐sophoroside which are present in B. sanguinea were also found in its intergeneric hybrids with Diacrium and Brassavola . These findings suggest that Cattleyopsis lindenii should not be transferred to Broughtonia and that B. domingensis, B. negrilensis , and B. sanguinea are separate species.
