Evolution of Hawaiian volcanoes went through the rejuvenated stage, while its younger neighbors, East Molokai and West Maui, have evidently done so. It is currently unknown what stage of development the submerged volcano of Penguin Bank is in. In recent years research at other seamounts, for instance Jasper Seamount, has confirmed that the Hawaiian model applies to other seamounts as well. Evolution of Hawaiian volcanoes The fifteen volcanoes that make up the eight principal islands of Hawaii are the youngest in a chain of more than 129 volcanoes that stretch across the North Pacific Ocean, called the Hawaiian-Emperor seamount chain. Hawaii's volcanoes rise an
Hawaiian lobelioids Hawaiian lobelioids The Hawaiian lobelioids are a group of flowering plants in the bellflower family, Campanulaceae, all of which are endemic to the Hawaiian Islands. This is the largest plant radiation in the Hawaiian Islands, and indeed the largest on any island archipelago, with over 125 species. The six genera can be broadly separated based on growth habit: "Clermontia" are typically branched shrubs or small trees, up to tall, with fleshy fruits; "Cyanea" and "Delissea" are typically unbranched or branching only at the base, with a cluster of relatively broad leaves at the apex and fleshy fruits; "Lobelia" and "Trematolobelia"
