Energy dispersive X‐ray fluorescence spectroscopy of thin sections of Laurencia snyderae Dawson shows bromine is concentrated in a cytoplasmic vesicle, the corps en cerise, a previously described structure characteristic of this genus. The presence of the brominated natural product β‐snyderol is shown to be related to the presence of corps en cerise in cortical cells. The presence of halogenated sesquiterpenoids in the corps en cerise of various Laurencia species is inferred from these data.
