* This Clavis is not intended to supersede the study of a proper Work on the Natural Orders, such as Lindley’s 
* Vegetable Kingdom,” but only as an aid to the Tasmanian botanist. A full and sufficient account of the Tasmanian 
Orders would be far too extensive for the limits of this volume, and properly belongs to introductory works on Botany.
