173 FLORA OF TABLE CAPE by J.H. Willis (with two plates and an appendix) Historical notes are provided on the original vegetation of Table Cape before its alteration by extensive agricultural clearing, as well as a description of the current vegetation. Floristic details of the four major current habitats arc given. A census is presented of 248 species of vascular plants, bryophytes and lichens, including exotics, recorded at thc Cape bctwccu 1832 and 1967. Key Words: flora, Table Cape, early vegetation, vascular plants, bryophytes, lichens, Tasmania. In BANKS, M.R. et al.

Hobart: 173-178. https://doi.org/10.26749/rstpp.124.2.173 INTRODUCTION The northwestern coast of Tasmania, between Burnie and Robbins Island, is interrupted by three bold equidistant bluffs - Table Cape near Wynyard, Rocky Cape, and Circular Head (or The Nut) at Stanley; all were given these names by Captain Matthew Flinders on 5 December 1798 (Flinders 1814). Table Cape and The Nut have much in common, both consisting of basalt, rising about 150 m above the sea and formerly carrying lofty eucalypt forest. Intervening Rocky Cape is quite different - white quartzite of Precambrian origin, with a predominantly heathland flora rich in species (at least 260 indigenous kinds, including 46 orchids). Floristic accounts of the vegetation on The Nut and Rocky Cape were published by Willis (I 966) and Firth (1969) respectively. It is, thus, appropriate that some record be made of the plants, both native and naturalised, known to inhabit the Table Cape promontory. HISTORICAL NOTES Settlement at Table Cape, with the consequent impact on the pristine vegetation, did not commence until the early l 850's - some 25 years after Van Diemens Land Company settlement at and around The Nut in 1826. Visiting missionary-botanist James Backhouse (1843) had given the first description of the Cape in its natural condition. Coming from Circular Head, doubtless along PLATE I the VDL Company's rough bush track, he ascended the Musk daisy-bush (Olearia argophylla), now extremely summit plateau on 14 November 1832 and was rare at Table Cape. (Photo: Fred Bishop.) impressed by the "luxuriant vegetation" which included "Stately Stringybarks and White Gums, attaining to Mercer (1963---64)described the activities of pioneer about 200 feet in height"; he specifically mentioned settlers in the area.
