Germination of Jedda multicaulis Clarkson,J.r. (Thymelaeaceae). An Example of Cryptogeal Germination in the Australian Flora

Abstract

The germination of Jedda multicaulis is figured and described. It provides the first record of cryptogeal germination for a member of the family Thymelaeaceae and demonstrates the habit for the first time in a woody dicotyledonous member of the Australian flora. Anatomical studies show the burying of the plumule is the result of a modification of the cotyledonary petioles. The germination pattern is considered to be primarily an adaptation to fire. It also provides a mode of recovery following grazing or trampling.
