These pictures show different aspects of the tropical rainforest fern Didymochlaena (Athyrium) truncatula as it was growing in Cairns Botanic Gardens, Queensland, Australia. There are very many different species of fern and they are distinguished from each other by such characteristics as subtle details of the shape of the fronds and pinnules, and by the specific arrangement and pattern of the spore-producing bodies on the undersides of the pinnules.
