Article presents some rare cone formations found from a small spruce in region of Punkaharju, Finland. In this case all the scales have developed into perfect, green needle leaves. Instead of a normal scale of a cone there are formations of buds that on the basal part of a cone resemble a normal bud, and hence develop into a branch. On the upper part of the cone formation the bud develops into scale of a cone.
The morphological form of the cones has been interpreted many ways. These anomalies resemble earlier observations and hence support the former theory of inflorescence. According the theory, the scales and scales of a cone are separate leaves, the scale corresponding to one leaf, the scale of a cone corresponding to two leaves. A cone is hence rather to be compared with a branching inflorescence than only one flower.
