APPENDIX. XXXlll 



the circumstance of the flowcr-heatls beiiia' formed in whorls 

 equal in power to that of the leaves ; so that as the latter 

 grew in threes the flower-head would necessarily consist of one 

 flower or of three and one, or of six and one; the first and the 

 third cases he knew, and he conjectured that the second 

 would be one day discovered. Although the Swan River 

 species is not referable to the second case, yet it confirms the 

 correctness of Dr. Brown's views, for the increased number 

 of flowers found in its heads is constantly some new power 

 of three ; in some specimens they are 3 x 4 + 1 = 13, and in 

 others 3x6+1 = 19; and to this I perceive no exception. 



Dryandras abound. In addition to D. Jiorihunda, ner- 

 vosa, bipinnatijida, and the elegant D. Frazeri^ whose leaves 

 are divided into fine awl-shaped lobes, there are the follow- 

 ing new ones ; viz. D.favosa^^'^^o. species near D. armata, 

 but the leaves have no hairs in their lacunae, except when 

 very young, the flower-heads are much smaller, and the 

 stigma is obtuse, not subulate ; D. carduacea^^^ a charming 

 species, with leaves like those of a Carthamus; D. stuposa,^^^ -d. 

 plant near D. formosa, and quite as handsome ; D. nohilis^^^ a 

 most splendid plant in the way of D. lomfifolia and tenuifolia, 

 with leaves from a foot to a foot and half long ; and finally 

 D. proteoideSy^^^ which has much the look of a Cape Protea.
