Abstract: | A phytochemical survey of the species of Bommeria showed that foliage of the members of this genus contains a variety of flavonol and flavone glycosides. The distributions of chemical and morphological characters in Bommeria correlated to circumscribe infrageneric affinities: B. hispida and B. subpalaecea comprise one evolutionary line, while B. pedata and B. ehrenbergiana form a second. Flavonoid data may also be applied in concert with spore morphology in defining intergeneric species groups within Bommeria and Hemionitis. |
