original home. It is not a common plant in oceanic islands, though it is one of the few 

 collected in South Trinidad by Dr Copeland. Seemann states that he found it far in the 

 interior of Viti Levu, but he adds that it is in none of the older Polynesian collections, 

 nor is it alluded to by the older botanists as existing in any part of Tropical Polynesia. 

 Jouan, loc. cit., states that Dr F. D. Bennett signalised the existence of a species of Ricinus 

 in the Marquesas Islands, where the natives called it " Toi," and that the same was very 

 common in the Sandwich Islands. Nadeaud does not include Ricinus in his Enumeration 

 of Tahitian plants, nor is it given in Bentham's Flora Australiensis ; but Bennett 

 (Gatherings of a Naturalist in New South Wales, p. 332) mentions that it grew commonly 

 in New South Wales, propagated by self-sown seeds, or conveyed by birds.
