Spermatophyte plants that have unenclosed, "naked seeds": The fifth extant division is the flowering plants, also known as angiosperms or magnoliophytes, the largest and most diverse group of spermatophytes. Angiosperms possess seeds enclosed in a fruit, unlike gymnosperms. In addition to the taxa listed above, the fossil record contains evidence of many extinct taxa of seed plants. The so-called "seed ferns" (Pteridospermae) were one of the earliest successful groups of land plants, and forests dominated by seed ferns were prevalent in the late Paleozoic. "Glossopteris" was the most prominent tree genus in the ancient southern supercontinent of Gondwana during the Permian
Seeds of Diversity become prone to colony collapse disorder, which threatens the production of many insect-pollinated crops. Native bees are also in decline, which is partly due to loss of nesting sites in plant debris and in open untilled ground, and partly due to reduced diversity of food plants. Seeds of Diversity initiated a project called Pollination Canada with the aim of increasing awareness of native bees and alternative pollinating insects in order to protect them, so that farmers and urban gardeners can decrease their dependence on honey bees. Pollination Canada has 28 other partner organizations. In February 2013, Gretchen Bauta, Canadian philanthropist
