At first sight this looks very much like Achyrocline capitata, Baker, from the mountains 

 of Brazil, but a closer comparison proves them to be distinct. Achyrocline capitata has 

 much thicker, almost coriaceous leaves, furnished with a short hard mucro ; narrower, 

 white involucral bracts and muricate achenes. It appears also to be of a more woody 

 nature thau our plant. The small specimen in Kew Herbarium was communicated by 

 Dr Buchenau for determination, and he was informed that it was a species of Achyro- 

 cline closely allied to Achyrocline capitata. In an enumeration (Abhandl. naturwiss. Ver. 

 Bremen, vii. p. 277) of the plants collected by Dr Copeland, Dr Buchenau records it as 

 Achyrocline capitata, Baker, with the remark, " Probably only a starved form of this 

 species, but possibly a distinct variety of it, or a very closely allied species." But from 

 Dr Copeland's narrative there is no reason to suppose that the plant was starved or 

 stunted ; on the contrary, he states that it grew abundantly and gregariously.

The castor-oil tree is now found in nearly all warm countries, but it is believed to be 

 indigenous only in the Old World, and most likely only in Tropical Africa.
