Abstract
The habit is described of a number of species of Elaphoglossum collected in Jamaica. Species were present with creeping horizontal rhizomes, shortly creeping or ascendent rhizomes, and one species with an ascendent or upright rhizome. The stelar structure of these rhizomes is described and it is shown that it bears a relation to the habit of the rhizome. A preliminary examination of the apices has shown that the symmetry of the rhizome is determined in the initiation of the primordial tissues; it is not secondarily induced by the habit of the rhizome. The occurrence of dormant buds is noted in all the species examined.
