Two plant species belonging to the genus Brunfelsia, commonly known as “Yesterday-Today-and-Tomorrow”, are closely related, however, differ by their flower fragrance. Flowers of Brunfelsia australis present a pleasant fragrance, whereas flowers of Brunfelsia pauciflora are scentless. SPME/GC/MS analysis on flower samples of both species of Brunfelsia indicated that flowers of B. australis emitted a fresh flowery fragrance, essentially comprising two monoterpenic compounds (linalool and (E)-ocimene). B. pauciflora, on the other hand, produced only a few sesquiterpenoids. These results are considered in an ecological and evolutionary context.
