APPENDIX.

Some genera with conglomerated capitula also occur, such as Cylindrosorus and Myriocephalus of Bentham, but they are of no beauty. Several Asteroideæ are found here, many of which belong to the inconspicuous genera Brachycome and Lagenophora; an Eurybia has also been described, and there is a genus nearly allied to Francœuria, the Asteridea pulverulenta,98 a plant of some beauty, with the appearance of an Aster Novæ Angliæ; it is not a little remarkable that with these there also occurs a plant of the genuine genus Aster,99 and of the Alpigenous section, with altogether its habit. The nearest approach to the vegetation of Cape Compositæ is met with here, in the case of Eriocladium pyramidatum,100 a plant related to Morysia, but very different in structure. There is even an imitation of the American Labiate Compositæ in the form of Amblysperma scapigera, Benth. a very handsome plant, with very large pale yellow or white flower-heads placed on a scape from a foot to a foot and half high; it is one of the finest plants of the order found on the continent of Australia.
