Quizplus · Accepted Answer

Hawaiian silverswords exhibit extraordinary morphological diversity, with different species exhibiting different shapes and sizes, ranging from small rosettes to large shrubs. While they are genetically diverse within each species, they are not as genetically diverse across different species. Their opportunities to exploit the "tree" way of life have not been preempted, as they have evolved to fill many different niches on the Hawaiian islands. They share a very distant common ancestor with plants in North America and South America, not Asia.
