Abstract

The inflorescence in all species of Salacca is enclosed in a chamber within the leaf base and is exserted through a slit on the abaxial surface of the leaf base. The inflorescence bud is interpreted ds an axillary meristem that becomes radially displaced by adaxial growth of the leaf primordium. A fine channel is produced from the leaf axil to the base of the inflorescence and persists at maturity. The channel and the bud chamber enlarge as the leaf elongates. They are lined by an epidermal layer. There is no cellular breakdown until the collapse and tearing of tissues of the leaf during inflorescence enlargement late in ontogeny. The vegetative bud is positioned about 1300 from the axil of its subtending leaf and lies directly below the abaxial inflorescence slit of the leaf above. Vegetative bud development was not observed, hut there is a suggestion of relatively late initiation. The separation of. Eleiodoxa from Salacca is supported by differences in the development of inflorescence and vegetative buds.
