Gas chromatography‐mass spectrometry evidence is presented for the presence of both phenylacetic acid (PAA) and 3‐indoleacetic acid (IAA) in vegetative and fertile tissues of the sporophyte of the ostrich fern [ Matteucia struthiopteris (L.) Todaro]. 3‐Indolepropionic acid, tryptamine and 3‐indoleacetonitrile were not found in tissue extracts, although small amounts of 3‐indolebutyric acid and tryptophol may have been present. PAA was present in amounts higher than those found in flowering plants, while LAA levels fall within the angiosperm range. The levels of both auxins were higher in the younger vegetative tissues than in mature vegetative or fertile pinnae. Recent evidence for the occurrence of angiosperm growth hormones in ferns is discussed.
