This study concerns the apomictic development of six bryophytes which has been carried out in a series of experiments in vitro under a controlled enivronment. It revealed that the filamentous gemmae of both Cyathcphorella japonica and Trachyloma indicum could produce protonemata and leafy gametophytes in aseptic cultures, in about 4 weeks. Schistochila fcrmrsana, a hepatic, generally reproducing by spores could also produce filamentous gemmae and from their tapering ends protonema was produced and thenceforth leafy buds. The seta of Trematodon longiccllis and Funcria hygrome-trica possess a high potential for developing apomictic gametophytes, so do the leaves of Pottia recta and Funaria hygrometrica and the calyptra of Trematodon. Products of these asexual bodies underline the capacity for apomixis, carrying with them their specific characteristics which are not easily changed by environmental factors.
