Abstract

The gemmae of Oedipodiella australis (Wag. & Dix.) Dix. are multicellular, lenticular diaspores (250-300 µm in diameter) and are found at the apices of gametophores which may also produce gametangia. The gemmae form rhizoids and one or two gametophores without an intermediate protonemal phase. Gametophores are produced from centrally positioned apices on opposite sides of the gemmae. Both sides must receive light in order to initiate apical growth and development into gametophores.
