The postgenital fusion of the carpel margins of the gynoecium of Laburnocytisus adamii (Poit.) Schneid. is described in detail using light and electron microscopy. In this species, the cells of dermal origin are characterized by osmiophilic bodies, facilitating the localisation of the enclosed dermal tissue at the site of fusion. The osmiophilic bodies are abundant in the outer epidermis and decrease in number and size towards the inner part of the enclosed dermal tissue. They are absent from the inner epidermis. Reasons for this distribution pattern are discussed. Variation in cell configuration and width of the enclosed dermal layer are probably caused by differences in growth rate between dermal and subdermal tissue.
