摘要:

SUMMARYNew observations on the fern genusHelminthostachysKaulfuss (Ophioglossales) are presented. Tetrarchy of the stele in the root is confirmed. The stomata inHelminthostachysare similar to those inOphioglossum palmatum. The unusual structure of the vegetative laciniae found at the distal end of each sporangiophore is again emphasized. In the rhizomes the presence of a periderm could be demonstrated.

SUMMARYA bridge was found to connect the dorsal side of the ovule with the ovary wall ofMangifera indicaL. (the mango). This bridge, termed aponticulus, is formed after pollination by the fusion of both an ovary protuberance and a protuberance of the ovule.
