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

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

 unquestionably belongs to the genus Gi/rostemon of Desfontaines, who has, first 

 in ISiiO, published one species [G. ra7nuIosuni) in the Memoires du Museum 

 d'llistoire Naturelle, v. 6; and again a second species (G. cotinifolium) in the 8th 

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

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

 Steriles," the second during Capt. Freycinet's Voyage, at the " Bale des Chiens- 

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

 seems disposed to arrange the plant with the Muhacca, though he is aware of its 

 affinity with the genus Hura, (in F uji/iorbiaccce,) in what concerns the general 

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

 Naturelles, it is confidently referred to the Euphorbiacea. I am most disposed to 

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

 considering it allied to the Uriicecr. I regret that I have not the ripe 

 seeds, nor the male fiowers, nor young female ones. My character, there- 

 fore, under the genus, of the Emhryo and Albumen, is copied from that of M.
