The compounds of formula a. ##STR1## wherein symbol X represents a --CHO group or a group of formula ##STR2## in which symbols R', taken separately, represent each a C.sub.1 to C.sub.4, linear or branched, saturated or unsaturated alkyl radical, or taken together represent a substituted or unsubstituted C.sub.2 to C.sub.4 alkylene radical; symbol R.sup.2 represents a hydrogen atom or a methyl radical; and R.sup.1 and R.sup.3 are different and represent each a hydrogen atom or a methyl radical; or of formula b. ##STR3## wherein the tert-butyl radical is located in position 5 or 6 of the aromatic ring and, either Y represents hydrogen and X and R.sup.2 have the meaning indicated above, or X and R.sup.2 represent each a hydrogen atom and Y represents a --CH.sub.2 CHO group or a group of formula ##STR4## in which R' is defined as in a.; or of formula c. ##STR5## wherein X and R.sup.2 have the meaning indicated in formula (Ia) and R represents a hydrogen atom or a methyl radical, the groups R being identical or different, are useful as perfuming ingredients for the preparation of perfuming compositions and perfumed articles to which they impart floral odor notes.
