Gladly would I, in describing tbis curious plant, have adopted the very 



expressive name given by its meritorious discoverers, were it not that i 



unquestionably belongs to the genus Gyrostemon of Desfontaines, who has, firs* 



in 1820, published one species {G, ramulosum) in the Memoires da Museam 



d'Histoire Naturelle, v. 6; and again a second species {G. cotin'ifolium) in the 9th 



vol. of the same work. Both are remarkably different from our present species. 



The first was detected during Capt. Baudin's Expedition, on the " h^^^ 



Steriles," the second during Capt, Freycinet'a Voyage, at the " Bale des Chieos- 



marins," by Gaudicbaud. In the last memoir on the subject, M. Desfontaines 



seems disposed to arrange the plant with the Malvace<Ey though he is aware of its 



affinity with the genus Ilura, (in E uphorbiace<s,) in what concerns the general 



structure of the capsule. In the plate given of the genus in the Diet, des Sciences 



Katurelles, it is confidently referred to the EuphorliacecE, I am most disposed to 



concur with the opinion of those who have gathered the present species, '" 



considering it allied to the Urticea:. I regret that I have not the rJp« 



seeds, nor the male flowers, nor young female ones. My character, iW^' 



fore, under the genus, of the Embryo and Albumen, is copied from that of W'
