Resumo

Sporophyte morphology has been traditionally used in pleurocarpous moss taxonomy. However, in the Pilotrichaceae gametophytic morphology still holds interesting and under-investigated characters. We investigated in greater depth the morphology and development of leaf papillae in the family and assess their usefulness to infer the family’s evolutionary history. Specimens were observed under the scanning electron microscope and seven morphological kinds of papillae were identified, as well as two different pathways of development. Results suggest that papilla morphology and development are phylogenetically informative in the Pilotrichaceae.
