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.
