The symbiotic association between the supposed parasite Janczewskia gardneri Setchell & Guernsey and its host Laurencia spectabilis Postels & Ruprecht was investigated. Mature plants of J. gardneri were pigmented, contained “typical” red algal chloroplasts when viewed by electron microscopy, and were capable of photosynthesis. Both J. gardneri and L. spectabilis incorporated 14 C‐label from NaH 14 CO 3 into similar compounds, including sugars (floridoside, isofloridoside, galactose, glucose) and amino acids (alanine, aspartic acid, glutamic acid, glycine, serine). Translocation of 14 C‐labeled photosynthetic products between mature J. gardneri and its host did not occur. This research suggests that mature individuals of J. gardneri are obligate epiphytes.
