I saw it in unfrequented spots in Chile, Entre Rios, and Banda oriental. In the latter country alone, very many (probably several hundred) square miles are covered with one mass of these prickly plants, and are impenetrable by man or beast. Over the undulating plains, where these great beds occur, nothing else can live. Before their introduction, however, I apprehend the surface supported as in other parts a rank herbage. I doubt whether any case is on record of an invasion of so grand scale of one plant over the aborigines”. speciation. Miss Amy Heeraman Form 5 Biology Friday 30. th. January 2015. VIDEO . .
